Abstract

The invention discloses a permanent magnet translational-motion type meshed motor. According to the permanent magnet translational-motion type meshed motor, a permanent magnet is used as a translational-motion rotor, two windings penetrate between two rotor magnetic poles, the two windings are wound on a motor shell in the mutually-perpendicular directions, four eccentric shafts are adopted to constraint rotation motion of the rotor, the energizing time and the direction of a current are appropriately controlled so that the rotor is driven to conduct the revolution motion in a radial plane, an inner gear ring which is fixedly connected with the rotor and a dead axel outer gear are driven to be meshed with each other, and the outer gear outputs the rotation motion. According to the permanent magnet translational-motion type meshed motor, a stator of the motor is a coil which is vertically wound on the motor shell in a staggered mode, and no stator core is arranged, so that eddy current loss is reduced. The rotor is the permanent magnet, so that the power density of the motor is improved.

Description

technical field [0001] The invention relates to a permanent magnet translational meshing motor, to be precise, to a mechanism that uses the magnetic field force generated between the winding and the permanent magnet of the rotor to convert electrical energy into mechanical energy, and is supplemented by an eccentric shaft translation restraining pair The invention makes the rotor move around the stator in a circumferential tangential direction, and the rotor drives the internal meshing gear reduction mechanism to output a low-speed, high-torque meshing motor, which belongs to the technical field of electric drive equipment. Background technique [0002] In recent years, good progress has been made both at home and abroad in the development and research of the integration of the new speed reduction mechanism and the electric motor. For example, the combination of the motor and the harmonic reducer makes the output torque increase and the structure size is significantly reduce...
