Wound rotor self-starting permasyn motor

The invention relates to a wound rotor self-starting permasyn motor, which belongs to the technical field of permanent magnet motors. The wound rotor self-starting permasyn motor comprises a fan housing, a fan, a front bearing end cover, a front bearing, a front motor end cover, a rear bearing end cover, a stator winding, a shell, a stator core, a permanent magnet, a rotor core, a rotating shaft, a rotor winding, an electric brush, a slip ring, a rear motor end cover, a rear bearing and a magnetic shielding bridge. The wound rotor self-starting permasyn motor has the following advantages: a wound rotor structure can improve the starting performance of the permasyn motor, namely the starting torque, reduce the starting current, improve the force-energy index, and simultaneously reduce the motor slip ratio by removing the rotor resistance gradually, improve the capability of pulling into synchronism to adapt to the operating condition requirement on low speed and large torque of overload starting, prevent impact to an electric network due to overlarge starting current or the incapability of starting the motor due to undersize starting torque, and ensure the smooth pulling into synchronism of the motor at the same time.
