Problems solved by technology

Since the motor has only one rotor, it can only achieve single-speed single-axis output
In applications such as torpedo propulsion, electric vehicles, and wind power generation, the motor is required to have a dual-axis output capability that provides two independent speeds, which cannot be achieved by traditional motors
[0003] In the existing dual-rotor motors, such as the dual-rotor hybrid compound permanent magnet motor disclosed in the application number 200510014393.2, there are brushes and slip rings, resulting in low efficiency and reliability
For example, the brushless dual-rotor motor disclosed in the application number 200610014350.9 realizes brushless and improves reliability. Because it adopts double-feed technology, the outer rotor is composed of windings, resulting in large copper loss. Manufacture or repair of outer rotor windings It is also very inconvenient, and its overall weight and volume are relatively large
Such as the application number is 200910179233.1 disclosed brushless feed double rotor motor has been improved and improved in terms of efficiency, maintenance, reliability, but because its three-phase stator winding, claw pole outer rotor, magnetic steel inner rotor are independent, so The utilization rate of the inner and outer rotors and the magnetic steel is only 2 / 3. In addition, the winding is inconvenient to embed, making it difficult to mass produce, and it is also inconvenient to repair and replace the intermediate phase winding.

Abstract

The invention discloses a brushless disc type double-rotor motor, which comprises a motor housing, a stator fixedly arranged inside the axial ends of the motor housing, an outer rotor arranged in the motor housing and matched with the stator, and One end of the motor housing is rotatably connected to the outer rotor output shaft fixedly connected to the outer rotor, and the inner rotor arranged in the motor housing and matched with both the stator and the outer rotor is rotatably connected to the other end of the motor housing and connected to the inner rotor. The output shaft of the inner rotor is fixedly connected, and the inverter is electrically connected to the stator. The present invention has the characteristics of a disc-type permanent magnet motor, the stator is fixed on the inner side of the end covers at both ends, the permanent magnet inner rotor is fixed on the inner rotor output shaft to rotate together, the claw pole rotor is located between the two-phase stator and the inner rotor, and They form an electrical angle of 90° to each other, and are fixed on the output shaft of the outer rotor to rotate together. Only a set of two-phase inverters can be used to coordinate the work to realize brushless power feeding and the speed / torque difference between the two shafts. adjust.

Description

technical field [0001] The invention relates to a double-rotor motor, in particular to a brushless disc-type double-rotor motor. Background technique [0002] Traditional motors generally consist of a stator and a rotor. Since the motor has only one rotor, it can only achieve single-speed single-axis output. In applications such as torpedo propulsion, electric vehicles, and wind power generation, the motor is required to have dual-axis output capabilities that provide two independent speeds, which cannot be achieved by traditional motors. [0003] In the existing dual-rotor motors, such as the dual-rotor hybrid compound permanent magnet motor disclosed in the application number 200510014393.2, there are brushes and slip rings, resulting in low efficiency and reliability. For example, the brushless dual-rotor motor disclosed in the application number 200610014350.9 realizes brushless and improves reliability. Because it adopts double-feed technology, the outer rotor is comp...
