Motor with magnetic steel sheet motor rotor and motor stator using double-coil double-group winding method

Abstract

The invention discloses a motor with a magnetic steel sheet motor rotor and a motor stator using a double-coil double-group winding method, belonging to motor structure. The motor adopts the structure that a groove hole is opened on a silicon steel sheet of a motor rotor, and a magnetic steel sheet is fixedly installed in the groove hole; and an A phase, a B phase and a C phase of a motor stator are respectively wound in double groups by double coils. After the non-magnetic resistance magnetic circuit design is combined with a new-method wire inserting technology of the stator, the invention has low full groove rate, easy wire insertion, simple production process, easy assembly and high finished product ratio, can be widely applied to the drive on electric automobiles, electro-tricycles, electric motorcycles, electric bicycles, and the like and has the advantages of small vortex and discharging current, high acceleration, low temperature, large torque, electricity-saving slide, and the like.

Description

technical field [0001] The invention relates to the structure of a motor, in particular to a motor in which a magnetic steel sheet is added to the rotor of the motor and the stator is wound in two groups with double coils. Background technique [0002] The structure of the brushless motor for electric vehicles in the prior art is the same as that of the common brushless motor, but the difference mainly lies in the integrated design of the motor controller, the connector and the brushless motor. Since the current electric vehicle brushless motor is difficult to meet the needs of high speed, there are disadvantages such as large resistance, large eddy current, high temperature, large discharge current, and inability to coast. [0003] Retrieval of relevant materials including Chinese patents shows that there are currently more than 500 related reports in Chinese patents, including nine reports on brushless motors for electric vehicles, but no relevant content with structural i...
