A dual electromechanical port motor based on unequal distribution of conductive cores

Abstract

The invention discloses a double-electromechanical port motor based on non-equidistant distribution of magnetic conduction iron cores. The double-electromechanical port motor comprises a stator, an intermediate rotor and an inner rotor which are coaxially nested in order from outside to inside. The stator comprises a first magnetic conduction iron core, two sets of windings and a plurality of first magnetic steels; the two sets of windings are arranged in grooves of the first magnetic conduction iron core of a cogging structure, and the numbers of pole-pairs of the two sets of the windings arenot the same; the first magnetic steels are located at the groove mouths of the first magnetic conduction iron core; the intermediate rotor comprises a plurality of third magnetic conduction iron cores which are arranged in a non-equidistant mode and are distributed at the outer side of the inner rotor to form an annular structure; and the first magnetic conduction iron core and the third magnetic conduction iron cores are coaxially sleeved. The intermediate rotor is formed by the third magnetic conduction iron cores with non-equidistant distribution, the stator is provided with the magneticsteels to increase the torque density of the motor by increasing the working harmonic waves, two magnetic field modulation motors are achieved in one motor structure, and the structure is more compact.

Description

technical field [0001] The invention belongs to the technical field of permanent magnet motors, and more particularly relates to a dual electromechanical port motor based on unequal distribution of conductive magnetic cores. Background technique [0002] In many industrial applications, especially in hybrid vehicles, continuously variable transmissions with variable speed and torque transmission ratios have attracted much attention. Existing hybrid vehicle power systems, represented by Toyota Prius, mostly use planetary gears to complete the decoupling between the internal combustion engine and the wheel load; the torque between the internal combustion engine and the wheels is completed by the torque of the additional motor / generator Decoupling: After the speed and torque of the internal combustion engine and the load are decoupled, the internal combustion engine can always work at the maximum efficiency point without affecting the wheel load operation. The system greatly i...
