Abstract

The invention discloses a new energy automobile low-noise permanent magnet motor. The new energy automobile low-noise permanent magnet motor comprises a motor and a sound absorbing cover. The sound absorbing cover is installed outside the motor. The motor comprises a motor base, a flange end cover, a front end cover, a rear end cover, a bearing, a first bearing outer cover, a second bearing outer cover, a first bearing inner cover, a second bearing inner cover, a stator, a rotor, two conjunction boxes and a counting device. The sound absorbing cover is divided into a first main body and a second main body. The first main body and the second main body are connected through a plurality of bolts, and each bolt is provided with a gasket. The flange end cover, the rear end cover and the bearing end cover are made of a gray cast iron material. Each bolt and each gasket are subjected to a galvanizing passivation technology. The sound absorbing cover is made of a toughened glass material. The new energy automobile low-noise permanent magnet motor has the advantages that the structure is simple, and the mounting and dismounting are convenient; the galvanizing passivation technology is adopted, so that the service lifetime is prolonged; in addition, the damping performance is good, and the wear resistance is relatively good.

Description

technical field [0001] The invention relates to a motor, mainly a permanent magnet motor applied to a new energy vehicle. Background technique [0002] New energy vehicles use unconventional vehicle fuels as power sources (or use conventional vehicle fuels and adopt new vehicle power devices), and integrate advanced technologies in vehicle power control and drive to form advanced technical principles and new features. Technology, new structure of the car. New energy vehicles mainly include pure electric vehicles, hybrid vehicles, fuel cell electric vehicles, hydrogen engine vehicles and other new energy vehicles. Most new energy vehicles use permanent magnet synchronous motors. [0003] Permanent magnet motor is a kind of electromechanical energy replacement device with magnetic field as the medium. The excitation coil in ordinary motor is replaced by magnetic steel, which improves the mechanical efficiency and reduces the volume of the motor; it also has energy saving, en...
