Not enough force in the stepper motor? When the stepper motor is used, it is not energetic, and it o

Stepper motors. There may be many solutions to the insufficient torque of the speed, which solution is cheaper, depending on the specific situation, and the increase in the driving voltage you mentioned is also one of the solutions. Since you don't know your specific situation, you can only analyze some solutions to the idea, you analyze according to the specific situation, consider the solution and verify.

First of all, look at the parameters of the motor and your working speed is very matched, the high speed to choose the low inductance, the low speed to choose the large inductance, the specific to see the motor distance frequency chart and your actual working speed range to consider. It is important to note that some users opt for a 6-wire stepper motor (i.e., a two-phase stepper motor with a unipolar drive) and use a bipolar driver.

4 wires) to drive, the wiring method is not the same, the characteristics will change greatly, simply put, the semi-winding wiring method is suitable for running high speed, and the large winding wiring method is suitable for running low speed and high torque, you need to learn more about it, you can search for articles specially introduced in this regard. Victor Electromechanical has rich experience in selection, please communicate separately if needed.

If there is no problem in matching the inductance parameters and the speed, the current is sufficient, or the high-speed torque is not enough, you can try to increase the driving voltage.

It is necessary to analyze the cause and related countermeasures based on the specific alarm information. For example, NEM556 has three kinds of faults: 1. The fault indicator flashes 1 time, indicating that the driver has a short circuit or overcurrent fault, and there are two reasons to cause: a. The wiring of the motor is wrong or the winding insulation is not enough; b. The power start or current sampling circuit of the driver is faulty; 2. The fault indicator flashes 2 times, indicating the voltage overvoltage fault, the main reason is that the rated working voltage of the driver does not match the power input voltage, for example, the rated working voltage of NEM556 is 50VDC, when the 48V linear power supply is used for power supply, the fluctuation of the mains power and the emergency stop of the motor are more likely to lead to the corresponding overvoltage fault.

3. The fault indicator flashes 4 times, indicating that the motor is out of phase fault, which is mainly caused by unreliable motor wiring and unequal motor wiring.

The power of the progressive motor is not enough, so where do you use the motor? How big the load, how big the motor should be, maybe your load is too large, the motor is not enough, you have to choose the right motor for your load.

The force of the stepper motor is not enough, I think the force of the stepper motor is not enough, you can ask others to buy more force, you can check the phone.

Not only is the power of electricity insufficient, but it depends on his reason, you can find out what the specific reason is, and you can transfer it to a special master to deal with this kind of person.

If the voltage of the motor is not enough, then there should be a problem with the hardware, and you need to replace it and buy a new one.

The torque output of the stepper motor is not a constant torque output, and the output torque will decrease with the increase of speed, so when designing and selecting, the moment frequency curve of the motor must be considered to leave enough output torque, otherwise there may be insufficient torque. You can refer to the formula in the article for calculation.

Stepper motor selection calculation table.

1: Installation and selection problems. There is not enough room for selection or the running speed is too fast.

4: The stepper motor is damaged, or the driver is damaged.

Related Notes:

1. The use environment should always be kept dry, the surface of the motor should be kept clean, and the air inlet should not be hindered by dust and fibers.

2. When the thermal protection of the motor is continuously activated, it should be found out whether the fault comes from the motor or the overload or the setting value of the protection device is too low, and the fault can be put into operation only after the fault is eliminated.

3. Good lubrication of the motor during operation should be ensured. The general motor runs for about 5000 hours, that is, the grease should be supplemented or replaced, and when the bearing is found to be overheated or the lubrication deteriorates, the hydraulic pressure should change the grease in time. When replacing the grease, the old lubricating oil should be removed, and the oil groove of the bearing and bearing cover should be cleaned with gasoline, and then the ZL-3 lithium grease should be filled with 1 2 (2 poles) and 2 3 (opposite poles) of the cavity between the inner and outer rings of the bearing.

The current setting is smaller, or the motor is smaller.

If the torque is not enough, you can try to adjust the drive, and if it doesn't work, change to a more torque.

Stepper motors. There are many reasons for not turning, and it is necessary to quickly determine the cause and maintain it accurately at the equipment application site to reduce the economic loss caused by the shutdown of the equipment. There are 2 reasons why motors are applied in the field:

1. For the problem of the motor, if there is a drive product of the same specification on the equipment at the application site, the driver can be selected to work normally.

To drive the motor of the bad shaft, if the motor can work normally, it can be ruled out that it is the fault of the motor, and it can be judged that it is the problem of the drive, on the contrary, if the motor does not work normally, it can be judged that the motor is bad and the motor needs to be replaced. 2. The problem of the drive can be roughly judged to be the problem of the driver through the first step. You can then connect the bad driver to the motor and power on, if the power light of the driver is not on (the driver of Norco Technology has a green power indicator), you can use a multimeter.

Measure the voltage of the power input terminal of the driver, if the voltage is abnormal, you can judge that the power supply is faulty, you can replace the power supply, if the power supply voltage is normal, you can judge the fault of the internal circuit of the driver, it is recommended to replace the driver or return to the factory for maintenance. If the power supply voltage is normal, and the power indicator of the driver is also normal, you need to see whether the fault indicator of the driver is alarmed, if it is not alarmed, you can use the shaft of the motor to screw whether it is forced, if the motor shaft is not forced, you can use a multimeter to test whether the ENA signal is normal, if the driver is enabled.

Effective, but not forced, judging that the driver may be faulty, it is recommended to replace the driver or return to the factory for repair. If the motor is normally forced, the pulse signal needs to be checked.

Whether the wiring is normal can be judged by the multimeter, and if the control pulse wiring is normal, it can be judged that the internal circuit of the driver is defective, and it is recommended to replace the driver or return it to the factory for repair. If the fault light of the driver flashes, the user can troubleshoot according to the fault prompt, for example, the NDM552 flashes 4 times, which is the motor phase loss fault, and the user can check whether the motor wiring is loose; Flashing 2 times, for the overvoltage fault, the user needs to check the voltage of the power supply, the driver in the working process, to ensure that the bus voltage of the driver does not exceed the rated working voltage of the driver, to reserve a certain safety margin.

The circuit problem is generally reflected in the old equipment, because the circuit is easy to ignore the problem, based on the signal and the motor circuit are possible, first to eliminate the method. 1: Both stepper motors do not rotate.

It is necessary to consider the power supply circuit. Control the signal input circuit, because the problem of the motor circuit can be basically eliminated. (It would be much easier if only one could work).

2: The power supply problem is also relatively simple, break the power supply of a group of drives v+, v-, if the power supply power is not enough, there is basically no problem with one. It is caused by the aging of the general power supply.

3: The line problem is much more complicated. But it's also intuitive, whether there are occasional glitches before the problem occurs.

It's just that the machine is good and bad. If there is, you are 100% sure of what the problem is. 4：

The signal problem is more complex, but there is less chance of two pulses being absent, and this is more common if one pulse controls two drivers (but it is rarely used). 5: Emergency stop switch problem.

If the emergency stop switch is broken, the motor will not move. I'm not a master. I can only roughly analyze the reasons.

And I don't need to be paid. Because I'm not professional enough.

Stepper motors. There will also be some faults or problems in the process of use, such as when you have connected the power supply, but the motor of the stepper motor does not rotate, which is one of the fault phenomena. So do you know what causes the stepper motor motor does not rotate, and how to solve it, the following I will answer you one by one for different possible reasons.

2. The subdivision is too small: then this one must choose the right subdivision, and the appropriate subdivision can be.

3. Whether the current setting is too small: this requirement selects the current when selecting the current.

4. a drive.

Protected: Power on again, if it can't be solved, refer to the description of the alarm indicator box.

5. Enable terminal level.

High: Controls the level of the enable port on the drive side to be low or to float it.

6. Whether the motor torque is large enough and whether it can drive the load, so we generally recommend that users choose a motor with a torque greater than the actual need of 50% 100% when selecting the motor, because the stepper motor cannot run under overload, even if it is instantaneous, it will cause out of step, and when it is serious, it will stop or move irregularly in place.

7. The input step of the upper controller.

Whether the current of the pulse is large enough (generally 10mA) to make the optocoupler.

Stable on, if the input frequency is too high to cause the receiver to be unreceived, if the output circuit of the upper controller is a CMOS circuit.

CMOS input drivers are also used.

8. Whether the starting frequency is too high, whether the acceleration process is set on the starting program, it is best to start accelerating to the set frequency from the starting frequency specified by the motor, even if the acceleration time is very short, otherwise it may be unstable or even inert.

9. Unable to respond to the control signal: increase the amplitude of the control signal, so that the high and low level time of the control signal are in line with the description of the manual.

When the stepper motor fails, we first have to analyze, and then look at the performance of the phenomenon according to the actual performance and experience to judge which reasons may be caused, find the cause of the failure and then determine it in a targeted manner, so as to better solve the problem. Reasons why the stepper motor does not rotate and solutions.

Problems with the motor or poor wiring of the motor winding, problems with the driver, problems with the control signal, problems with the connection between the motor and the transmission structure, etc., will cause the motor to run abnormally.

The stepper motor is boring when it is used, hello dear, I am happy to answer for you. There are the following reasons why the stepper motor is not strong when it is used:1:

Installation and selection issues. There is not enough room for selection or the running speed is too fast. 2：

The driver parameter setting is incorrect, and the startup frequency in the controller is too high in the parameter setting. The above (you can run it by reducing the speed, you can find out whether it is a selection or a program problem) 3: If the equipment is in use, after a period of time, the friction of the finch-cracked structure load increases or there is a sudden increase in external resistance.

Especially after the structure is damaged by grinding lead). Check whether the structure runs smoothly after power failure. 4：

The stepper motor is damaged, or the driver is damaged. The above is all the answers of the answer, I hope it can help you, and I wish you a happy life

1. Check the line, if it is the first time to wire, be sure to confirm the phase line of the motor, or wire according to the drawing. Pay attention to the wiring of the driver with reference to the statement on the first floor, don't make a mistake; If this problem occurs with the motor in use, first check whether the motor circuit is damaged and disconnected, if it is disconnected, it will also cause the situation you said.

2. Check the load, the motor is disconnected from the load to check if the load is too heavy.

3. Check the frequency of the input pulse, the input frequency of the stepper motor should not be too high, and if it is too high, it will also cause the motor to only ring but not rotate.

The stepper motor is an open-loop control motor that converts the electrical pulse signal into angular displacement or linear displacement, and is the main actuator in the modern digital program control system, which is extremely widely used.

In the case of non-overload, the speed of the motor, the position of the stop only depends on the frequency of the pulse signal and the number of pulses, and is not affected by the change of load, when the stepper driver receives a pulse signal, it drives the stepper motor to rotate a fixed angle in the set direction, called the "step angle", and its rotation is to run step by step at a fixed angle. The angular displacement can be controlled by controlling the number of pulses, so as to achieve the purpose of accurate positioning; At the same time, the speed and acceleration of the motor can be controlled by controlling the pulse frequency, so as to achieve the purpose of speed regulation.

Stepper motor is a kind of induction motor, its working principle is to use electronic circuits, direct current into time-sharing power supply, multi-phase timing control current, use this current to supply power to the stepper motor, stepper motor can work normally, the driver is for stepper motor time-sharing power supply, multi-phase timing controller.

Although stepper motors have been widely used, stepper motors cannot be used under conventional conditions like ordinary DC motors, AC motors. It must be composed of a double ring pulse signal, a power drive circuit, etc., and the control system can be used. Therefore, it is not easy to use stepper motors well, and it involves many specialized knowledge such as machinery, motors, electronics, and computers.

As an actuator, stepper motor is one of the key products of mechatronics, which is widely used in various automatic control systems. With the development of microelectronics and computer technology, the demand for stepper motors is increasing day by day, and they are used in various fields of the national economy.
