Abstract
The utility model relates to a switch reluctance motor. The utility model is characterized in that the size of the middle part to the root part of the magnetic pole of a stator is reduced to form a depressed groove, and under the condition that the size of the tip part of the magnetic pole of the stator is invariable, the pole width and yoke width of the stator are reasonably matched, the torque is increased by 16%. The utility model makes the torque constant and descends obviously the vibration and noise, besides, the utility model has the advantages of simple structure, fastness, high durability, wide speed regulation range and good performance.
Description
The utility model belongs to a kind of motor with stepless speed regulation.
Common buncher structure is made up of the winding coil on stator, rotor, motor shaft and the magnetic pole of the stator.Powered by the pulse power by speed regulator, the pulse power makes torque be pulsating character, and mechanical oscillation and noise are bigger.For reducing vibration and noise, on the stator salient poles structure, increase extremely widely, vibration reduces, but torque also reduces, and reduces extremely widely, and torque increases, and vibrating noise also increases.This is that people make every effort to the problem that solves for a long time.
At the problems referred to above, order of the present utility model is to provide the switched reluctance motor that a kind of torque is big, vibration noise is little.
The utility model provides a switched reluctance motor, comprises stator, rotor, central shaft, magnetic pole of the stator, winding coil, it is characterized in that the middle part of magnetic pole of the stator reduces to form groove to the anterior relatively size of root, and this groove is satisfying to be rectangular channel.Under the situation of the anterior size constancy of magnetic pole of the stator, stator poles is wide and stator yoke is wide is reasonably mated, thereby motor is reached under the situation of torque upper limit, the torque that reduces vibration and noise or improve motor in limited time under noise reaches.Experiment test calculates and shows, motor oscillating and noise are near down in limited time, and torque improves 16%.
The utility model has solved the problem that the motor oscillating noise reduces from structure, under the constant situation of motor torque, makes motor oscillating, and noise obviously descends, and simple in structure, sturdy and durable, adjusting range broadening, has improved the motor properties quality.
Fig. 1 is the utility model sectional structure schematic diagram.
Further narrate structure of the present utility model below in conjunction with figure.
Among Fig. 1, central shaft 1, stator 3, rotor 4 are formed basic structure, rectangular channel 6 is made in magnetic pole of the stator 5 middle parts to root both sides on the stator, winding coil 2 is on rectangular channel, wide and the wide coupling of stator yoke of stator poles, torque increases, and under the constant situation of holding torque, the vibration and the noise of motor reduce.
