Abstract

The invention relates to a commutating structure for a disc type permanent magnet motor, which comprises an electric brush and an armature winding, wherein the part of a conductor of the armature winding is formed by stacking, pressing and connecting formed coils in series, and the electric brush comprises a positive pole and a negative pole, is arranged at the center of the armature winding and is in contact with coil edges of the formed coils. The commutating structure can change the traditional armature winding structure, carry out current commutation by subtly utilizing the formed coils of the armature winding to be in direct contact with the electric brush, simplify the structure and the shape of the motor, and reduce the external dimension and the weight of the whole machine, thereby having the advantages of small size, compact structure, low cost and the like.

Description

technical field [0001] The invention relates to a commutation structure of a motor, in particular to a commutation structure of a disc permanent magnet motor. Background technique [0002] At present, the existing disc permanent magnet motor usually uses a commutator to realize the commutation of the current. Since the commutator is installed in the permanent magnet motor, the overall structure and shape of the motor are complicated, and the weight of the motor is increased. size and cost. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a commutation structure of a disc permanent magnet motor, which simplifies the overall structure and shape of the motor. [0004] The technical solution adopted by the present invention to solve the technical problem is to provide a commutation structure of a disc permanent magnet motor, including brushes and armature windings, and the conductor part of the armature windings is f...
