What should I do if the motor is short circuited? How do you know if a small motor is short circuite

1) The grounding caused by moisture in the winding should be dried first, and when it is cooled to about 60-70, it should be poured with insulating paint and then dried.

2) When the insulation at the end of the winding is damaged, re-insulate at the grounding place, paint it, and then dry it.

3) When the winding grounding point is in the slot, the winding should be rewound or part of the winding components should be replaced.

Finally, a different megohmmeter is applied.

Measurements are taken to meet the technical requirements.

When the motor winding is short-circuited, due to the uneven distribution of the magnetic field of the ions, the three-phase current is unbalanced, and the vibration and noise of the motor are aggravated during operation, and the motor cannot be started when it is serious, and a large short-circuit current is generated in the short-circuit coil.

Causes the coil to heat up quickly.

And burned.

If the motor is short-circuited, the first thing to do is to stop the work of the motor in time to prevent more serious consequences.

Then, the cause of the short circuit needs to be found. This may involve checking whether the insulation of the motor circuit is broken, whether the motor is overloaded, whether the operation of the motor controller is normal, and whether there are any anomalies in the environment in which the motor is installed, etc.

Once you have found and resolved the cause of the short circuit, you can try restarting the motor, but make sure that all the issues have been thoroughly resolved before attempting to start to prevent the short circuit from occurring again.

First see if the motor has any traces of burning and blackening, smell whether there is a mushy smell inside, if it is a short circuit in the external wire, it will not burn the motor, it will only cause tripping.

If the accident has been a long time, and the external wires of the motor are not damaged, it is recommended to use a multimeter to measure the resistance of the motor winding, the normal resistance is basically zero, otherwise the winding itself is burned out, and then measure the resistance between the three-phase windings, the normal is infinite, otherwise the windings are burned out.

If these are normal, then check the resistance between the three-phase and the case, the normal is infinite, otherwise it is a short circuit between the phase wire and the case.

If it's okay, it's your empty opening problem.

Why does the motor coil not short circuit when connected to power, hello! When there is a current in the wire, it will produce a magnetic field around the wire, and this magnetic field will hinder the current change in the wire, but the single strand wire has a very small effect on the obstruction section in the air, so the voltage is directly added to the wire, which will produce a large current, resulting in a short circuit, and the wire is coiled around the wire, which is equal to gathering the magnetic field around the wire, the more turns, the stronger the obstruction effect, and the magnetic permeability of the iron core is much better than that of air. It is understood that the addition of the iron core can greatly improve the hindrance effect of the magnetic field on the current change, so the motor winding will not cause a short circuit when the power is turned on. But everything has a quantity problem, if the structure of the motor or the data setting is not reasonable, there will still be problems.

Hope it helps!

1. Use the shake meter, that is, the megohmmeter, to measure the insulation resistance of the motor between phases and to the ground, and you can judge whether there is an interphase open circuit and a ground short circuit fault. 2. The interphase short circuit should be untied after the neutral point is unlocked, and the phase-to-phase resistance should be measured with a shake meter, and the triangle should be disassembled and measured. 3. The inter-turn short circuit should use the balance bridge DC resistance tester, and you will know it when you test it.

4. In the case of three-phase voltage balance, the three-phase current of the basic balance of the original and the distribution disorder gradually or suddenly becomes very unbalanced, and at the same time, the temperature rise of the motor increases and the load capacity decreases, and the short circuit between turns of the stator winding of the machine can be preliminarily determined. 5. Test the DC resistance with a bridge, the unevenness of the three-phase DC resistance is large, that is, an inter-turn short circuit occurs in a phase change ** Ming Sell Number: under normal circumstances, the three-phase DC resistance imbalance is 1%, and if it exceeds this value, it means that the coil has the possibility of inter-turn short circuit.

Summary. Hello, glad for your problem, the three-phase motor bearing is broken and causes a short circuit, first of all, you can check the connection inside the machine, if there is an abnormality, you can try to repair the connection or replace the parts to avoid a short circuit. In addition, it is also possible to check the fuse of the machine for damage, and if it is damaged, it should be replaced as soon as possible.

Hello, very happy for your problem, the three-phase motor bearing is broken and causes a short circuit, first of all, you can check the connection inside the machine, if there is an abnormality, you can try to repair the connection or replace the parts to avoid a short circuit. In addition, it is also possible to check whether the fuse of the machine is damaged, and if it is damaged, the limb should be replaced as soon as possible.

Fellow, I really didn't understand, I can be more specific.

Of course, if the three-phase motor in the town is broken, it may cause a short circuit. At this time, the short-circuit circuit should be checked in time, and it should be cleaned up, and then the new bearing should be replaced in time to ensure the normal operation of the three-liquid rolling coarse phase motor.

If the motor with brake cannot move after the circuit is short-circuited, it may be caused by the damage to the motor controller or the motor stops working due to the short circuit. The exact cause requires further investigation.

First of all, you can check whether the circuit is short-circuited, if there is a short circuit, you should immediately cut off the power supply. Then, check whether the cable connection between the motor control base source and the motor is loose or damaged. If the connection is loose or damaged, it should be repaired or replaced in time.

If there is no short circuit in the circuit and there is no problem with the cable connection, you can check if the motor is working properly. You can use a tool such as a multimeter to check if the motor has a current output. If the motor does not have a current output, it may be that the motor itself is faulty and needs to be inspected and repaired with professional equipment.

In addition, if the motor with brakes suddenly stops working under load, it may be due to the protective measures caused by the motor overheating. At this point, you can wait for the motor to cool down and then try to start again.

In short, the failure of the motor with brake after the circuit short circuit may be caused by a variety of reasons, which need to be checked and checked one by one, and corresponding maintenance measures should be taken. It is recommended that you take your vehicle to a professional repair shop for repair.

After the circuit is short-circuited, the motor with brake cannot move, which may be one of the following reasons:

1.Brake system failure: A failure of the brake system may cause the motor to fail to brake. For example, problems such as brake failure, insufficient brake fluid, or clogged brake ducts can cause the motor to fail to brake.

2.Motor failure: Motor failure may also lead to motor cavity-free braking. For example, problems such as motor overheating, insufficient supply voltage, or damaged motor coils can cause the motor to fail to brake.

3.Wrong circuit connection: If the circuit is connected incorrectly, it may cause a short circuit in the circuit, which will cause the motor to fail to brake.

In order to solve the problem of counting shirts, the following measures are recommended:

1.Check that the brake system is working properly and replace the faulty part.

2.Check if the motor is working properly and replace the faulty part.

3.Check that the circuit connection is working properly and repair any damaged circuits.

If the above measures do not solve the problem, it is recommended to seek professional help to ensure the safety of the circuit and motor.

Answer: The reason why the brake motor cannot move after the circuit is short-circuited is that the circuit short-circuit will cause the current to be too large, and the motor protector may automatically trip, so as to prevent the motor from being damaged. After the circuit is short-circuited, the brake motor may be prohibited from running by the protector, so it is necessary to solve the circuit short-circuit problem first, and then reset the protector after the limb posture to make the brake motor run again.

Explanation: Circuit short circuit refers to the direct connection between two or more conductors in the circuit, so that the current is in the short circuit part**, which can easily lead to circuit overload, and the motor protector automatically trips to protect the motor from damage. When a short circuit in the circuit occurs, the brake motor may be prohibited from running by the protector, which is a normal protective measure.

Solution: First of all, you need to check whether the circuit is short-circuited and solve the short-circuit problem. Then you need to reset the motor protector, the specific method can refer to the motor manual or ask the professional technician. If the problem cannot be solved, it is recommended to contact professional maintenance personnel for maintenance.

In conclusion, circuit short-circuits are a common problem that needs to be solved in time, otherwise it may lead to damage to the motor. Therefore, it is necessary to pay attention to safety when using the electric core machine, and carry out regular maintenance to ensure that the circuit is unimpeded.

The reason why the motor with brake cannot move after the circuit is short-circuited may be that the motor is subjected to excessive current, resulting in internal damage to the motor or the protection measures are activated. If the circuit is short-circuited and the motor cannot work normally, you can first check whether the circuit has obvious line faults, such as wiring errors, short circuits and other problems. If there is no problem with the circuit, you can try to remove the brakes and see if the motor can work properly.

If the motor still does not work properly, it is recommended to replace the motor or seek professional repair from the trace.

Extended supplement: The motor needs a certain current when it is running, but if the circuit is short-circuited or the voltage is too large, the motor will be subjected to excessive current, resulting in heating, damage and even **. In order to protect the motor, components such as fuses and fuses are usually added to the circuit to prevent excessive current.

In addition, the motor may also fail due to long-term use or quality problems, and the motor needs to be replaced or repaired in time to ensure the normal operation of the equipment.

A short circuit in the circuit may cause the motor to not work properly, including the situation where the brake motor does not work properly. This situation may be caused by insufficient power supply of the main circuit due to a short lead circuit or a failure of the brake motor.

Here's how to fix it:

1.Check the circuit for short circuits. If a short circuit is found, you need to solve the circuit short circuit problem first to ensure that the power supply of the circuit is normal.

2.Check the brake motor for damage. You can judge whether the motor is damaged by checking whether the motor has abnormal sounds, inflexible rotation, etc. If the motor is damaged, a new one needs to be replaced.

3.Check if the motor connection is loose or damaged. If the motor connection is found to be loose or damaged, the motor connection needs to be re-fixed or replaced.

4.Check the controller for damage. If the above methods do not solve the problem, the controller may not be faulty and you need to replace it with a new controller.

In short, a short circuit in the circuit is a cause for the brake motor to not work properly, and the circuit and motor need to be carefully inspected to find the old stool and repair the obstacle. If you are unable to resolve the issue, it is advisable to seek professional technical support.

If the motor with brake cannot move after the circuit is short-circuited, it may be because the circuit is short-circuited and the motor cannot work normally. Collapse motors with brakes are usually composed of a motor and brakes, and if the circuit is short-circuited, the motor will not work properly and the brakes will not be released, resulting in the motor not being able to rotate.

The way to solve this problem is to first rule out the cause of the short circuit seepage, check whether there is a short circuit in the circuit, and if so, the circuit needs to be repaired. If there is no problem with the circuit, then it is possible that the motor or brake itself is faulty and needs to be replaced or repaired. It is recommended that you go to a professional car repair shop or 4S shop for overhaul and repair to ensure safety and reliability.

A short circuit in the circuit may cause the motor to not work properly, while a motor with brakes will automatically brake when it stops working, preventing the motor from continuing to run. Therefore, if the motor does not work after the circuit is short-circuited, it may be caused by the motor braking system being activated.

In this case, it is necessary to eliminate the problem of short circuit in the circuit, find the cause of the short circuit and solve it. Then, inspect the various parts of the motor and brake system to determine if there is any problem with the brakes, such as whether the brakes are locked or if the motor rotor is stuck. When the troubleshooting is done, re-test the circuit and motor to see if it is working properly.

If the above methods do not work, it may be necessary to further check the relevant parameters of the circuit and motor, such as voltage, current, resistance, circuit layout, etc., to stimulate this to determine the possible cause of the fault and take appropriate measures to repair it.

Answer: A short circuit in the circuit will cause excessive current, and the brake motor may stop working due to current overload, resulting in a situation where power cannot be driven.

Explanation: A brake motor is an electric motor that is used to brake a vehicle. When the circuit is short-circuited, the current will increase suddenly, which may exceed the bearing range of the brake motor, causing the motor to not work properly. Brother cavity.

Solution: First of all, you need to check whether the circuit is short-circuited, find the location of the short-circuit and repair it. Then you can try to replace a brake motor with a higher load capacity to avoid problems caused by current overload.

In addition, electronic components such as overload protectors can be considered to protect the safety of the brake motor and the entire circuit.

In short, a short circuit in the circuit may have a negative impact on the brake motor, and it is necessary to repair and strengthen protection measures in time to ensure the normal operation of the vehicle and the safety of driving.
