Abstract

An axial magnetic field electromagnetic planetary gear power transmission belongs to the field of automobile motor and aims to solve the problem that in a conventional double-rotor motor, a rotational winding only can induct current through an electric brush and a slip ring, so that the operation efficiency is low, the reliability is low, and the electric brush and other components are required to be maintained frequently. The power transmission is characterized in that two stators are fixed on the left end surface and the right end surface of a casing; a p-m rotor is positioned between the two stators and outside a magnetic flux regulating rotor; a primary machine drives the magnetic flux regulating rotor to rotate; q protrusion units are arranged on two sides of the magnetic flux regulating rotor respectively; magnetic fields with 2n poles are arranged on two sides of the p-m rotor respectively; the stators on two sides form magnetic fields with 2p poles respectively after being powered on; the relational expression that p equals to the absolute value of hn and kq is met. According to the invention, the motor is of two structures including an axial symmetric structure and an axial monolateral structure. The motor provided by the invention can be applied to electric automobiles, wind power generation, and torpedo propulsion occasions.

Description

technical field [0001] The invention relates to a transmission composed of double-rotor motors, which belongs to the field of automobile 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 shaft and the ...
