Brushless-fed dual-rotor motor

Abstract

The invention relates to a brushless-fed dual-rotor motor, belonging to the technical field of a permanent magnet motor. The brushless-fed dual-rotor motor solves the problems that the traditional motor only can realize single shaft output with a single speed, while the existing two-speed double-shaft output motor needs an electric brush slip ring to feed a winding, so that the operating efficiency is reduced, the reliability is lowered, the parts such as an electric brush and the like are needed to be maintained frequently, etc. A stator of the motor is fixed inside a shell, a permanent magnet rotor is fixed on an output shaft of the permanent magnet rotor, a claw pole rotor is positioned between the stator and the permanent magnet rotor and fixed on an output shaft of the claw pole rotor, and the output shafts of the permanent magnet rotor and the claw pole rotor are respectively connected with the shell by bearings. The motor can be used for providing the difference values of torqueand rotating speed between two rotating shafts, so as to be applicable to the industrial technology of the two mechanical rotating shafts which need different rotating speed and simultaneously work.

Description

technical field [0001] The invention relates to the technical field of permanent magnet motors. 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] At present, the commonly used method to achieve dual-axis output is to rotate the stator of the traditional motor. Since the stator has a winding that needs to be fed, it is necessary to use a mechanism such as a brush slip ring to feed the stator winding, which will lead to a decrease in operating efficiency. , reduced reliability, and frequent maintenance of brushes and other components. Contents of the invention [0004] In order to solve the problem that ...
