Motor with high starting torque

Technical Field

The utility model relates to a motor technical field, in particular to motor of high starting moment.

Background

The shaded pole motor is a motor with a simpler structure in a single-phase alternating current motor, and mainly comprises a rotor assembly, a stator assembly, a solenoid assembly, a support assembly and a connecting fastener. The stator structure is provided with a short circuit ring, also called an electrode shaded pole ring, after the motor is electrified, induced current in the winding generates an induced magnetic field which is transmitted through a stator iron core with magnetic conductivity, and the magnetic field generated in the iron core generates induced current in the short circuit ring, so that the part of the magnetic pole covered by the magnetic field generates a magnetic field which is delayed by a little compared with the part of the magnetic field which is not covered by the magnetic field, thereby forming a rotating magnetic field and enabling the motor to rotate. At present, the common torque increasing mode needs more cost increase and is inconvenient to operate.
