[0002] The shielded pole motor is the simplest one among single-phase alternating current motors, and its structure and process are relatively simple. Unlike general alternating current motors, the shielded pole motor is mostly a two-pole motor, and has a short circuit ring on the stator structure. The short circuit ring is actually equivalent to the starting winding of the motor. When the motor is powered on, the induced current in the winding generates an induced magnetic field, which is transmitted through the stator core with magnetic conductivity. The magnetic field generated in the core produces an induced current in the short circuit ring, thereby causing the part of the magnetic pole covered by the shield to generate a magnetic field that lags behind the part of the magnetic field that is not covered, thereby forming a rotating magnetic field to make the motor rotate. The short circuit ring needs to be welded during processing.
