What are the stator and rotor functions of an alternating current motor?
If it is a three-phase AC motor, the stator generates a rotating magnetic field to drive the rotor. If it is a single-phase AC motor, the stator generates an alternating magnetic field with a magnetic field phase difference of 90 degrees to drive the rotor. The action of the rotor is that, in the case of an asynchronous motor, it produces an electric current in the stator rotating magnetic field. According to the principle of the right-hand rule, it will operate in the direction of the rotating magnetic field at a speed less than the rotation of the rotating magnetic field. And the mechanical energy generated is transmitted to the dragging device.
The role of the rotor of an AC motor is:The rotor is a part of the magnetic circuit of the motor, which forms the whole magnetic circuit of the motor together with the stator core and the air gap. The rotor iron core is generally laminated with 0.5mm thick silicon steel sheets. The rotor cores of medium and small AC motors are mostly installed directly on the motor shaft. The rotor core of the large AC motor is mounted on the bracket, and the support is sheathed on the shaft.
The role of the stator of an alternating current motor is:As part of the magnetic circuit of the motor and embedded stator windings. The stator core is laminated by 0.5mm thick silicon steel sheet, and the two sides of the brick and steel sheet are coated with insulating paint to insulate the sheets and sheets so as to reduce the core loss caused by the rotating magnetic field in the stator core. A plurality of same grooves are punched inside the stator core to be inserted into the stator winding.
