Can a 220 volt motor be connected to a 380 volt?

A 220 volt motor cannot be connected to a 380 volt voltage because of the voltage level.

No, it will burn out the motor.

Motor Wiring Specification:

1) Motor wiring.

1: The stator of the AC motor before the motor is wired.

The coil should measure the insulation resistance value or absorption ratio.

1000V shake table for low-voltage motors.

The insulation value should not be less than 1 megaohm, and if it does not meet the requirements, it will be dried according to the actual situation.

2: The cable core connected with the low-voltage motor should be connected with the terminal lugs of the specifications, and be bolted with the motor lead-out wire, which should be firmly connected and the phase correct. At the bolt connection between the cable core and the motor lead-out wire, wrap it with self-adhesive tape first, and then wrap a layer of PVC tape on top of the self-adhesive tape after reaching a certain thickness.

3: When the cable enters the motor junction box, there should be a waterproof bend.

4: All motors should be reliably grounded, and share a grounding system, grounding resistance.

No more than 4 ohms.

2) Motor trial operation.

1: Before the motor starts, check whether the coupling is disconnected, and if it is really unable to be disconnected, it should be tested together with the mechanical part of the no-load after obtaining the consent of the factory.

2: When the motor is started for the first time, it should run for 2 hours under no-load conditions, record its no-load current and compare with its factory technical data, there should be no obvious difference between the motor and its factory technical data, the motor has no abnormal sound, and the temperature of each part of the motor should not exceed the provisions of the technical conditions of the product, for sliding bearings.

The temperature should not exceed 80 degrees, rolling bearings.

The bearing temperature should not exceed 95 degrees.

Can't connect, the voltage is too high.

Not to mention the difference between single-phase electricity and three-phase electricity, the key is how you connect the missing wire.

Summary. Hello dear, very happy to solve the problem for you :

The 380-volt motor can be changed to 220 volts, how to change it, which should be based on the original working wiring method of the existing equipment, such as the motor, the original connection method is a star connection, just change the star connection method to the delta connection method, with a split-phase capacitor, a starting capacitor, so that the original three-phase 380-volt three-phase electric motor, can be connected to the 220 volt single-phase power supply to work normally.

Can a 380 volt motor be changed to 220 volts?

Hello dear! I have seen your question here, and I am trying to sort out the answers of several friends, and I will give you a reply in five minutes, please wait a moment! ^

Dear, hello, very happy to solve the problem for you: 380 volt motor can be changed to poor such as 220 volts, how to change, this should be based on the original working wiring method of the existing equipment, such as the virtual guess of the motor, the original connection is a star connection, just change the star connection to the triangle connection, with a split phase capacitor, a starting capacitor, so that the original three-phase 380 volt three-phase electric motor, it is known that it can be connected to the 220 volt single-phase power supply to work normally.

Can a 380 volt voltage be connected to a 220 volt electrical appliance? Hello dear, 380 volts can not be connected to 220 volt electrical appliances, this is because the rated voltage of 380 volts is greater than the rated voltage of 220 volt electrical appliances, the rated voltage between the two can not be matched, and the voltage of 380 volts is three-phase electricity, 22o volt electrical appliances are two-phase electricity for household use, if the voltage of 380 volts is connected to 220 volts electrical appliances, the electrical appliances will be burned out. I hope it can help you.

If my answer is helpful to you, please give a thumbs up (in the lower left corner), I look forward to your like, your efforts are very important to me, and your support is also the motivation for my progress. Finally, I wish you good health and a good mood!

The 380V voltage can be connected to 220V electrical appliances, but it needs to be modified.

The voltage between the live wire and the neutral wire is 220 volts, and the voltage between the live wire and the ground wire is also 220 volts. Temporary electricity can be made as a ground pile, and the ground pile must be done by professionals, safety first.

Transformation method: pseudo-zero line.

Precautions for ground piles: use No. 4 galvanized angle steel to sharpen one end as the grounding electrode, the depth of vertical driving into the ground should not be less than 2 meters, galvanized flat steel for connection, and its grounding resistance is required to be less than 4 ohms after it is done.

Summary. 1: If the original three-phase motor itself is triangulated:

Connect any two of them to the 220V incoming line, and the remaining one binding post is connected to one end of the capacitor, and the other end of the capacitor can be arbitrarily connected to one end of the incoming line. But then the power will be reduced a lot.

2: If the motor is originally a star connection, the original star connection of the motor can be changed to a triangle connection, and then the above wiring method can ensure that the original motor power remains unchanged.

3: The capacitor can be selected according to 20UF per kilowatt, and the withstand voltage is higher than 630V.

How to change a 380-volt motor to a 220-volt motor.

1: If the original three-phase motor itself is triangular: connect any two of its fingers to the 220V incoming line, and let a binding post be connected to one end of the capacitor, and the other end of the capacitor can be arbitrarily connected to one end of the incoming line.

But then the power will be reduced a lot. 2: If the motor is originally a star connection, the original star connection of the motor can be changed to a triangle connection, and then the above wiring method can be used to protect the original motor power of this bureau.

3: The capacitor can be selected according to 20UF per kilowatt, and the withstand voltage is higher than 630V.

Do you use a starting capacitor or a running capacitor?

When it comes to operating capacitors, they are often associated with starting capacitors. The single-phase current flowing through the single-phase motor cannot produce a rotating magnetic field, so the single-phase motor must add a starting winding to use capacitors to separate the phases, so that the current in the two windings produces a phase difference of nearly 90 to produce a rotating magnetic field. The starting winding of the single-phase motor is mostly used when starting, once the motor starts the delay, the centrifugal switch makes the starting capacitor and the power supply out of the yard, so as to disconnect the starting winding.

However, there is also a mode of operation, next to the starting capacitor, another capacitor (running capacitor) is connected, the motor is started, and when it is in normal operation, the centrifugal switch cuts off the starting capacitor, but does not cut off the running capacitor and the starting winding, that is to say, the starting winding participates in the normal operation of the motor, and this capacitor is called the running capacitor. In this way, the output power of the single-phase motor can be increased. After the motor starts, the starting capacitor is disconnected by the separation switch, and the running capacitor participates in the operation with the starting coil.

The starting capacitance capacity is large, about 200 microfarads, and the operating capacitance capacity is small about 20-30 microfarads. There is also a single-capacitor motor, which shares a capacitor for phase shifting and operation, and participates in the operation itself after starting. Its capacity is determined according to the power of the motor.

Generally between 8-20 micro-methods. What is the function of the operating capacitor? In fact, in simple terms, this is the capacitor that ensures that the capacitor can operate properly.

For the starting capacitor, it can be simply understood as a starting function, in the case of normal operation after starting, the starting capacitor will stop working, and the running capacitor will maintain the normal operation of the equipment.

Hello dear<> can a 380 volt voltage be connected to a 220 volt electrical appliance? The 380V power supply can be connected to a 220V electrical appliance, but it should be used in the case of three phases and four wires. In fact, what we call 220V is itself part of a three-phase 380V power supply.

If it is a three-phase three-wire, there is no neutral line, and 220V will appear in the "Y" connection in a completely balanced state, but 220V electrical appliances cannot be used in this way.

The three-phase alternator uses the principle of electromagnetic induction, in which the electric potential is induced by the wire-cut magnetic field line, and the mechanical energy of the prime mover is converted into electrical energy output. The synchronous generator consists of two parts: a stator and a rotor. The stator is the armature that emits electricity, and the rotor is the magnetic pole.

The stator is composed of an armature core, a uniformly discharged three-phase winding, a base and an end cover.

As long as the output of the three-phase generator has a neutral (neutral wire), a voltage of 220 V can be output.

Three-phase alternating current is a form of transmission of electrical energy, referred to as three-phase electricity. Three-phase AC power supply is a power supply composed of three alternating currents with the same frequency, equal amplitude, and 120° difference in phase. Three-phase alternating current has many uses, and most of the alternating current electrical equipment in the industry, such as motors, use three-phase alternating current, which is often referred to as the three-phase four-wire system.

In daily life, single-phase power supply, also known as lighting electricity, is mostly used. When lighting electricity is used, one of the three phases is used to supply power to the consumer, such as household appliances, and the other wire is the fourth wire in the three-phase four-wire, that is, the neutral line, which leads from the neutral point of the three-phase electricity.

If the voltage between the phases emitted by the three-phase generator is 380V, then the voltage between each phase and zero is 220V.

Hello:——As long as there is a neutral wire (neutral wire) at the output end of the three-phase generator, it can output 220 V voltage: any live wire and neutral line of three-phase 380 V is 220 V, and their relationship is:

380 v ＝ 220 v 。

Yes, as 220V is usually required; Product information can be found for details.

Hello dear, I'm honored to answer for you! There are many ways to change the 380-volt motor to 220 volts, and here we focus on the method of changing the 220-volt in the absence of three-phase electricity. Any two of the three outlets originally connected to the three-phase motor are connected to the two ends of the power supply (L-live wire, N-neutral wire) respectively, and the remaining one is connected before the capacitor.

2. The other end of the capacitor is connected to one end of the power supply, and it is connected to the live wire or the neutral wire, depending on the required steering, and the steering is different for different connections. Another more secure way is to install a single-phase 220-volt input three-phase 380-volt output inverter, so that the motor does not need any changes.
