Can any AC motor 220 and 380V control positive inversion? What are the conditions?
There are commonly used reverse switch control (Figure 1), switching control (Figure 2) and AC contactor controlSingle-phase series motor (portable electric tools) can be 2 lines of stator winding connected between the carbon brush can brush with control of the motor is reverse.Single-phase shaded pole motor with self shading coil can not change the position of the short circuit and embedded in the stator slots, the motor is not reversed.
Single phase motor has two coils, three heads, two ends of the coil and connected together to a head (public side), the starting coil of a head, a head coil operation, starting capacitor connected between the operating coil and start coil, the power supply is connected in common end and operation coil when the motor is transferred, connected to the power supply public end and start winding motor reversal.
All three phase motor, the 3 phase line in any two lines can be switched to control the motor positive and reverse, commonly used AC contactor control, reverse switch control (small capacity) and so on.Single-phase capacitor running motor ends of the main winding or secondary winding can be controlled on the motor is reverse.
