Abstract

The invention discloses a four-phase double-faced flat plate type transverse magnetic field permanent magnet motor for solving the technical problem that a stator armature of an existing three-phase assembled magnetic type transverse magnetic field permanent magnet motor is difficult to wind. According to the technical scheme, the motor is formed by two rotor discs and a four-phase stator, wherein each rotor disc corresponds to a two-phase stator, each motor rotor is formed by the fact that a permanent magnet is embedded in a permanent magnet embedded plate, and a rotor strength reinforcing ring is additionally arranged in the center of each rotor; each motor stator is formed by a winding, an E-type silicon steel sheet and a conducting magnetic stripe, each E-type silicon steel sheet is folded to be a motor stator magnetic pole, and one conducting magnetic stripe is added between every two stator magnetic poles; the armature of each phase stator is formed by an inner circular ring winding and an outer circular ring winding which are placed in two grooves of each E-type silicon steel sheet respectively, the four-phase stator of the motor is positioned through screw rods on the periphery, 180 / 4 N mechanical angles are sequentially staggered, and the N is the number of poles of the motor. Through the arrangement of the structure, the stator windings of the motor are designed to be of a circular ring shape, winding of the armature of the motor is simplified, and machining and assembling of the motor are facilitated.

Description

technical field [0001] The invention relates to a permanent magnet motor, in particular to a four-phase double-sided flat plate transverse magnetic field permanent magnet motor. Background technique [0002] With the development of electric drive technology, people have more and more urgent requirements for high torque, low speed and direct drive motors. Due to the structural characteristics of traditional motors, the further improvement of motor torque density is limited. In 1986, H. Weh of Germany proposed a transverse magnetic field motor, whose main magnetic field line direction is perpendicular to the rotor motion plane, which can further increase the torque density of the motor. In recent years, transverse field motors have made great progress. [0003] refer to Image 6 . The document "Application Publication No. CN102820756A Chinese Invention Patent" discloses a disk-type three-phase magnetism-concentrating transverse magnetic field permanent magnet motor. The mot...
