What about a single phase AC motor reversing?
The steering of a single AC motor has different rotating principles according to the structural differences. The following is a reference for professional data:Single phase motors are usually divided into four types: split phase, push cabinet, hood type and ordinary series excitation type. Since the structure of the four is different, the method of changing its rotation direction is also different
Landlord is not the end of the motor cover installed, or change the end of the motor cover, or change the location of secondary winding joints, you can achieve the steering transform
(1) the split phase motor consists of two sets of coils, one is a running coil, and the other is a starting coil with higher resistance. Reversing the two line ends of any of the two sets of coils allows the motor to rotate in reverse direction.(2) there is a set of armature coils, a commutator and a group of brush holders, which are approximately the same as the direct current motor, but the brush is shorted by the centrifugal switch. Usually, the relative position of the moving brush on the commutator can change the rotation direction of the motor.(3) since the pole motor is operated by only one set of coils on the AC power supply, the rotation direction of the motor can not be changed by reversing the line ends. Usually, the stator core is removed and the motor is reversed in one direction.(4) the rotation direction of the motor can be changed by changing the power head of an armature or a magnetic field of an ordinary serial excited motor, and the principle is the same as that of a serial excited DC motor.
