Abstract

A rotor of a permanent magnet DC motor provided by the present invention, the rotor uses an even group of coils, and y1 is N is a natural number, so as to realize short wire winding; there are two hooks on each commutator piece, so as to reduce the number of commutator pieces, and also realize flexible winding and symmetrical winding. Moreover, the size of the end portion is also small, the processing time is short, the power density of the whole machine is high, the noise and vibration are small, and the manufacturing cost is low, and it can be applied to all even-numbered slot connections.

Description

technical field [0001] The invention relates to the field of motors, in particular to a rotor of a permanent magnet DC motor. Background technique [0002] Permanent magnet DC motor is a kind of DC motor that uses permanent magnets to establish a magnetic field. It has good mechanical characteristics and adjustment characteristics, and is widely used in the automobile industry. The permanent magnet DC motor is mainly composed of a stator, a rotor and a brush commutator. The rotor is composed of stacked armature punches. The punches can be divided into odd slot punches and even slot punches according to the number of slots. Odd slot punching can reduce the positioning torque generated by the armature teeth, but this structure has a large unilateral magnetic pull, which is likely to cause noise and vibration problems. It is necessary to consider optimizing the stator magnet or armature to weaken the magnetic pull, but The effect is limited. Even-numbered groove punching has ...
