Abstract

The invention discloses a low-noise permanent magnet motor for a new energy automobile, which comprises a motor and a sound absorbing cover, wherein the sound absorbing cover is installed outside themotor; the motor comprises a motor base, a flange front 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, asecond bearing inner cover, a stator, a rotor, two junction 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 ironmaterial; each bolt and each gasket are subjected to a galvanizing passivation technology; and the sound absorbing cover is made of a toughened glass material. The low-noise permanent magnet motor provided by the invention for the new energy automobile is simple in structure and convenient to assemble and disassemble; the galvanizing passivation technology is adopted, so that the service life is prolonged; and the damping performance is good, and the wear resistance is also relatively good at the same time.

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. 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, environment...
