Abstract

The invention discloses a three-phase separation stator yoke-free modularized axial magnetic flux permanent magnet disc type wheel hub direct-driven motor, and belongs to the field of brushless direct-current motors. The problem of an existing wheel hub motor is solved. The three-phase separation stator yoke-free modularized axial magnetic flux permanent magnet disc type wheel hub direct-driven motor comprises an outer rotor, an inner stator and a fixed shaft, wherein three groups of stator supports of the inner stator are arranged on the fixed shaft in parallel; 2p iron core mounting holes are uniformly formed in the stator support in the circumferential direction and are used for mounting a stator iron core module which enwinds a stator winding 5; a rotor support of the outer rotor is provided with a rotor connecting outer tube and four circular ring rotor back irons, so that three annular chamber areas are formed; a group of stator supports is accommodated in each of the annular chamber areas; 4p permanent magnets are uniformly arranged on the two inner end faces of each of the annular areas; the permanent magnets are magnetized in the axial direction, the magnetized directionsof the two adjacent permanent magnets on the same end face are opposite to each other, and the magnetized directions of the permanent magnets which are arranged in the same annular chamber and positioned on the two end faces are opposite, and the permanent magnets of the three annular chambers are distributed sequentially at different electrical angles of 120 degrees in the circumferential directions.

Description

technical field [0001] The invention belongs to the field of brushless DC motors. Background technique [0002] Energy and environmental protection are major problems facing the development of the world today. Electric vehicles are gradually recognized by the market due to their zero emissions and environmental friendliness. Most of the electric drive systems used by electric vehicles on the market today mainly adopt centralized The drive system is similar to traditional gasoline and diesel engines. The drive motor is placed on the front or rear of the chassis of the car, and the power is transmitted to each wheel through the drive shaft. The hub motor can flexibly arrange the drive system on the The drive wheel of the car is ingeniously integrated with the wheel, and can independently control each wheel hub motor, so that the system control efficiency can be effectively improved. [0003] With the continuous progress of the design, the hub motor of the conventional permane...
