Magnetic field modulation type electromechanical energy converter used for hybrid electric vehicle

Abstract

The present invention discloses a magnetic field modulation type electromechanical energy converter used for a hybrid electric vehicle. The magnetic field modulation type electromechanical energy converter comprises a chassis, and a stator, an outer rotor, a modulation ring and an inner rotor are arranged inside the chassis orderly from outside to inside. The inner surface of the stator is equipped with 12 salient poles, a three-phase centralized winding is placed in a cogging of the stator, and a first air gap is arranged between the stator and the outer rotor. The outer surface of the outer rotor is equipped with 8 outer rotor salient poles, 8 outer rotor permanent magnets are placed on the inner surface of the outer rotor uniformly, and a second air gap is arranged between the outer rotor and the modulation ring. The modulation ring is characterized by arranging 10 non conductive magnets and 10 magnetizers alternately to form a cylinder, the inner rotor is equipped with 12 inner rotor salient poles, an inner rotor permanent magnet is pasted on each inner rotor salient pole, and the three-phase centralized winding is embedded in a cogging of the inner rotor. The magnetic field modulation type electromechanical energy converter used for the hybrid electric vehicle of the present invention enables the transmission efficiency to be improved and the mechanical vibration, the mechanical wear and the noise to be reduced, thereby improving the reliability of a device, reducing the maintenance cost, and prolonging the service life of the device.

Description

technical field [0001] The invention belongs to the field of hybrid electric vehicles, and in particular relates to a magnetic field modulation electromechanical energy converter for a hybrid electric vehicle. Background technique [0002] With the increasingly severe environmental pollution and increasingly scarce oil resources, it is urgent to seek clean energy and reduce pollution emissions. Pure electric vehicles can use non-petroleum energy and can achieve zero emissions, which is an ideal way to solve current problems. However, the energy density of batteries is much lower than that of gasoline, which cannot meet people's actual needs. Adopting hybrid electric vehicles has become one of the effective ways to alleviate the current problems.
