An electric motor, an end cap thereof and a manufacturing method of the end cap are provided. The end cap includes an insulating body and a filter circuit board mounted to the insulating body. The filter circuit board includes at least two power conductors for receiving an external power source, an insulating support frame integral with the at least two power conductors, and at least one filter element. One end of the at least one filter element is connected to a corresponding power conductor, and the other end of the at least one filter element is grounded.

Motor, end cap and manufacturing method thereof

A motor, a rotor and a sleeve are provided. The motor includes a stator and a rotor which includes a shaft, a rotor core, a sleeve, a commutator, and a rotor winding wound on the rotor core. The sleeve is arranged between the rotor core and the commutator. The sleeve includes a first end portion close to the commutator, a second end portion close to the rotor core, and a middle portion therebetween. An outer diameter of the first end portion is smaller than an outer diameter of the middle portion, and the outer diameter of the middle portion is smaller than an outer diameter of the second end portion. An end of the commutator close to the sleeve has a groove, and the first end portion of the sleeve is placed in the groove. The rotor has a good seismic performance.
