Abstract

The invention provides a motor which comprises a movement part and a stator coil, wherein the movement part consists of more than one permanent magnets and more than one magnetic conduction parts; thepermanent magnets are uniformly distributed; same magnetic poles of the permanent magnets are opposite; the permanent magnets are axially magnetized; the magnetic conduction parts are arranged in gaps between the adjacent permanent magnets, made of ferromagnetic materials, and fixedly connected with the permanent magnets; the movement part is arranged in a movement part fixing device; the statorcoil is arranged outside the movement part in a sleeving manner, and fixed in a stator coil fixing device; and the stator coil fixing device is made of a magnetic conduction material. According to themotor, the movement part consisting of the magnetic conduction parts and the permanent magnets is designed, the same poles of the permanent magnets are opposite, the stator coil is matched, an interaction force (a magnetic field force and an ampere force) of the stator coil and the movement part wholly acts on a tangential direction, and a torque angle is constant as zero, so that the performanceand the efficiency of the motor are improved.

Description

technical field

[0001] The invention relates to the technical field of motors, in particular to a motor. Background technique

[0002] A motor is a device that uses an energized coil (that is, a stator winding) to generate a rotating magnetic field and acts on the rotor to form a magnetoelectric force rotation torque, thereby converting electrical energy into mechanical energy. Motors are divided into DC motors and AC motors according to different power sources. At present, motors are widely used in machinery manufacturing industry, metallurgical industry, coal industry, petroleum industry, light textile industry, chemical industry and various other mining enterprises, which play an important role in the development of national economy.

[0003] An electric motor usually includes a rotor and a stator, and uses ampere force or magnetic field force to rotate the rotor and output power through an output shaft. There is an included angle between the magnetic field force betwee...
