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
The present invention relates to the motor technology field, particularly a kind of radial coreless permanent magnet motor.
Background technology
Advantages such as the coreless machine is in light weight with it, loss is little, noise is low, vibration is little are applied to various control occasions widely, but it is poor also to exist air gap flux density sine degree simultaneously, because the problem of processing technology causes problems such as power grade is lower, makes its due advantage not have and can significantly embody.
Summary of the invention
In order to solve the problem of above-mentioned existence, the object of the present invention is to provide a kind of radial coreless permanent magnet motor, the stator winding of this motor is anodontia slotless configuration, rotor adopts the concentrated magnetic magnet structure, improve the air gap flux density waveform greatly, thereby made motor that very high efficient and power factor arranged.
A kind of radial coreless permanent magnet motor of the present invention, comprise shell, support, rotating shaft, bearing, rotor, stator, shell places on the support, and machine shaft at the middle part of shell, radially sets gradually rotor, stator by the bearing fixing on the inwall of shell both sides around rotating shaft; Rotor portion comprises permanent magnet, rotor field spider, and rotor field spider is fixed on the machine shaft, is used for support rotor, permanent magnet be distributed in rotor field spider around; Stationary part comprises stator yoke, stator winding, stator winding be arranged on permanent magnet around, the solenoid of stator is fixed on the stator yoke between stator winding and the shell.The magnetic structure of rotor is the concentrated magnetic structure: the every utmost point of rotor has n piece permanent magnet, and the magnetizing direction of permanent magnet differs 180 °/n respectively successively, makes the air gap flux density ripple form Sine distribution; Every permanent magnet blocks number that extremely descends can according to circumstances be selected, and the piece number is many more, the approaching more sine of air gap flux density.Stator yoke portion and rotor yoke are equipped with non-magnet material.Non-magnet material is bakelite or aluminium etc.
Advantage of the present invention be no teeth groove, brushless, simple in structure, efficient is high, power factor is high, vibration is little, do not have static friction torque and higher advantages such as power grade are arranged; And stator, rotor all do not have iron core, have fundamentally eliminated iron loss, thereby have improved efficiency of motor; Adopt the concentrated magnetic magnet structure, improved the air gap flux density waveform, greatly reduced influence of harmonic; Stator adopts anodontia slotless configuration, has solved the electromagnetic noise that is caused by teeth groove, because the ac-dc axis magnetic resistance is identical, has also just eliminated magnetic resistance moment simultaneously, and is reliable.The present invention can adopt existing support, and stator, rotor manufacture craft are simple.
