Wound-rotor motors are a common type of motor with a complex internal structure that requires correct wiring to work properly. This article will introduce the wiring method and wiring diagram of wound-rotor motors to help you connect correctly and avoid motor damage or circuit failure.

1. Basic structure of wound-rotor motors

Wound-rotor motors are composed of stators, rotors, end covers, etc., of which the stators and rotors are the key components of the motor. The stator is composed of multiple coils, and the wires in the coils are wound into rings to form an electromagnetic field. The rotor is the moving part of the motor, which drives the motor to rotate through the action of electromagnetic force.

2. Wiring method of wound-rotor motors

1. Wiring method of single-phase wound-rotor motors

Single-phase wound-rotor motors are a common type of motor with a relatively simple wiring method. The wiring method is as follows:

(1) Label the three terminals of the motor as 1, 2, and 3 respectively.

(2) Connect the phase wires of the power supply to terminals 1 and 2 respectively.

(3) Connect the neutral wire of the power supply to terminal 3 of the motor.

(4) After the connection is completed, use a multimeter to check whether the insulation resistance of the motor is normal, and then perform a power-on test.

2. Wiring method of three-phase winding motor

Three-phase winding motor is a commonly used type of high-power motor, and its wiring method is relatively complicated. Its wiring method is as follows:

(1) Label the three terminals of the motor as U, V, and W respectively.

(2) Connect the three-phase wires of the power supply to the three terminals of the motor respectively, with phase A connected to the U terminal, phase B connected to the V terminal, and phase C connected to the W terminal.

(3) After the connection is completed, use a multimeter to check whether the insulation resistance of the motor is normal, and then perform a power-on test.

IV. Precautions for winding motor wiring

1. Before wiring, carefully check the motor mark to ensure that the wiring is correct.

2. During the wiring process, pay attention to the insulation resistance of the motor to avoid damage to the motor due to poor wiring.

3. After the wiring is completed, a power-on test should be performed to ensure that the motor can operate normally.
