Abstract

The invention relates to a permanent-magnet synchronous motor comprising a stator and a rotor, wherein the stator and the rotor comprise 8 and 6 magnetic poles respectively, the rotor magnetic poles are distributed alternatively, the two pairs of stator magnetic poles are also distributed alternatively. The invention realizes self-starting function, compact conformation, short magnetic circuit, and large output torque moment.

Description

technical field [0001] The invention relates to a synchronous motor, in particular to a permanent magnet synchronous motor. Background technique [0002] As we all know, permanent magnet synchronous motors are widely used in various fields of driving constant speed machinery because of their small size, energy saving, constant speed and other performances. The structure of the permanent magnet synchronous motor includes two basic parts: the rotor and the stator. The stator includes iron core, stator coil (also called winding or armature), casing and end cover, and the rotor is composed of permanent magnets. After the stator coil is energized, the armature rotating magnetic field is generated in the air gap, and its rotation speed is synchronous speed. [0003] {n}r / min=60{f}Hz / p (1) [0004] In the formula, f is the frequency of the AC power supply; p is the number of pole pairs of the stator rotating magnetic field. [0005] In the existing permanent magnet synchronous ...
