Title:
DIRECT CURRENT MOTOR
Document Type and Number:
WIPO Patent Application WO/2020/073405
Kind Code:
A1
Abstract:
Provided in the present invention is a direct current motor, comprising a housing; m pairs of brushes fixed inside the housing; a stator arranged inside the housing, containing m pairs of main magnetic poles corresponding to the m pairs of brushes and containing n excitation winding portions; and a rotor arranged inside the stator. The direct current motor has such features as: each pair of main magnetic poles contains an S-polarity main magnetic pole and an N-polarity main magnetic pole, and the polarities of two adjacent main magnetic poles are different; the positions of two brushes in each pair of brushes are adjacent, and each pair of brushes contains an S-polarity corresponding brush corresponding to the S-polarity main magnetic pole and an N-polarity corresponding brush corresponding to the N-polarity main magnetic pole; and each excitation winding portion contains m excitation winding units, the m excitation winding units respectively correspond to the m pairs of main magnetic poles, and each excitation winding unit is formed by respectively manufacturing excitation coils on a corresponding pair of main magnetic poles by means of an insulating conductor strip composed of a metal line wrapped with an insulating layer, with m being a positive integer not less than 2, and n being 1 or 2.
