Abstract

The invention provides a radial magnetic field modulating brushless double-rotor motor, belonging to the field of motors. The invention aims to solve the following problem: rotating windings in the existing double-rotor motors need electric brushes and slip rings to introduce current, so that the operation efficiency and the reliability are reduced and the parts such as the electric brushes need to be frequently maintained. The motor is characterized in that stators of the motor are fixed on the inner side walls of a shell; a permanent magnet rotor is fixed on a permanent magnet rotor output shaft; a modulation ring rotor is arranged between the stators and the permanent magnet rotor; the permanent magnet rotor output shaft is connected with the shell and the modulation ring rotor in a rotary manner; one end of the permanent magnet rotor output shaft is fixed on the modulation ring rotor and is connected with the shell in a rotary manner; the stators are electrified to form 2p-numbered pole magnetic fields; 2n-numbered permanent magnet units of the permanent magnet rotor are uniformly distributed and arranged on the excircle surface of a permanent magnet rotor core along the circumferential direction; the permanent magnet rotor rotates to form 2n-numbered pole magnetic fields; q-numbered magnetic blocks and q-numbered insulating blocks interlace on the excircle surface of a support of the modulation ring rotor along the circumference direction; and p is equal to hn plus kq.

Description

technical field [0001] The invention relates to a radial magnetic field modulation type brushless double-rotor motor, which belongs to the field of motors. Background technique [0002] The dual-rotor motor has two rotors and rotating shafts with independent rotational speeds, which can realize dual-axis independent drive, so it has broad application prospects in electric vehicles, wind power generation, torpedo propulsion and other occasions. [0003] A common method for realizing dual-shaft drive in existing dual-rotor motors is to use the rotor of the traditional motor as one rotor and connect it to a rotating shaft, and rotate the stator of the traditional motor as another rotor and connect it to another rotating shaft. Among them, one rotating shaft is connected to the prime mover as the energy input end, and the other rotating shaft is connected to the load as the energy output end. By adjusting the frequency of the current in the rotating stator winding, the input sha...
