Problems solved by technology

However, because the magnetic field strength of this kind of permanent magnet is too large, it is difficult to optimize the air gap between the rotor and the stator of the motor using this type of permanent magnet, and the size of the magnetic force is also difficult to adjust, resulting in difficulty in starting the motor; I researched it in 2004. Between the stator and the rotor in the motor, install an air gap adjustment sleeve made of non-magnetic material (see Chinese patent 2004100468889). Although this solution solves the difficult problem of starting the motor, due to the adopted The air gap adjustment sleeve is made of non-magnetic material, which has a certain barrier effect on the magnetic field and reduces the magnetic field strength of the permanent magnet to do work, so that the motor generates more heat and the temperature rises faster during operation; at the same time, Its efficiency is lower than that of existing similar motors

Abstract

This invention discloses one new type of permanent magnetic direct current synchronous motor, which comprises motor axis, stator shell, left and right cover, permanent magnetic iron, stator coil set and magnetic adjusting cover with simple structure and easy starting and high energy-saving energy. The invention relates to one ideal permanent direct current synchronous motor to take place of traditional one.

Description

technical field [0001] The invention relates to a permanent magnet direct current motor, in particular to a novel high-efficiency permanent magnet direct current synchronous motor. Background technique [0002] In the prior art, most DC synchronous motors use two windings of a stator and a rotor. Since both the stator and the rotor of this motor need to input electric energy, the energy consumption is relatively high and the efficiency is low. In recent years, some permanent magnets made of rare earth NdFeB permanent magnet materials with high performance and strong magnetic field strength (magnetic field strength up to 4000 Gauss) have appeared to replace stator windings or replace rotor windings. DC synchronous motors, this type of DC Since the stator or rotor windings of synchronous motors have been replaced by high-strength permanent magnets, the electric energy required by the replaced windings is saved, so the energy-saving effect is more significant. However, because...
