Permanent magnetic multi-phase dipolar high speed motor

Abstract

The invention provides a permanent magnetic multi-phase dipolar high speed motor comprising an annular magnet, namely an outer rotor, wherein an annular high-conductivity magnet, namely a stator is placed in the annular magnet, a groove is formed in the high-conductivity magnet, and winding groups are placed in the groove; a winding group C and a winding group D on the left side are correspondingly connected with a winding group B and a winding group A on the right side through winding group connecting lines to form winding groups AD and winding groups BC; all winding groups BC are connected to serve as a cathode, the winding groups AD are powered in sequence clockwise, and then the magnet rotates clockwise; if the winding groups AD are powered in sequence counterclockwise, the magnet rotates reversely; the permanent magnetic multi-phase dipolar high speed motor can be randomly made into large, middle and small high speed motors, the windings therein can be symmetrically provided with required torque motors, the motor generates no heat, the motor can normally operate at a high speed in the case of a very large torsion, and can also keep an optimal state of the power consumption.

Description

technical field [0001] The invention relates to a permanent magnet high-speed DC motor, in particular to a permanent magnet multi-phase two-pole high-speed motor. Background technique [0002] Ordinary permanent magnet high-speed motors are completed with three-phase and two poles. Although this kind of motor can achieve high-speed operation, the torque cannot reach the torque of multi-pole motors; the permanent magnet high-speed motors currently on the market are all micro motors. They all appear in six sets of windings and three phases. Even if there are more than six sets of windings, they also work in three phases. Its internal work needs to be conducted by means of electrical conduction. It not only consumes more energy, but also the motor heats up when the motor is working. With certain security risks, there is no better solution at present. Contents of the invention [0003] In order to solve the problem of low torque of common high-speed motors, high energy consum...
