Abstract

The radial permanent magnet motor without iron core comprises a shell on base, a rotation shaft arranged rotor and stator radially along circular, a bearing to fix the motor rotation shaft on center of shell; wherein, the rotor comprises a frame on shaft and permanent magnet around the frame; the stator comprises a stator yoke with stator coil and stator winding around permanent magnet. His invention has simple structure, high efficiency, little vibration, and no static friction torque; it eliminates iron consumption at root, and decreases greatly the effect of harmonic wave.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a radial coreless permanent magnet motor. Background technique [0002] Ironless motors are widely used in various control occasions due to their light weight, low loss, low noise, and low vibration. Low-level problems make its due advantages not clearly reflected. Contents of the invention [0003] In order to solve the above existing problems, the object of the present invention is to provide a radial coreless permanent magnet motor. The stator winding of the motor is a toothless and slotless structure, and the rotor adopts a magnetic gathering type permanent magnet structure, which greatly improves the air gap magnetic Dense waveform, so that the motor has a high efficiency and power factor. [0004] A radial coreless permanent magnet motor of the present invention comprises a casing, a machine base, a rotating shaft, a bearing, a rotor and a stator. A rotor and a stator a...
