Abstract
The invention relates to high performance magnetic resistance electrical machinery, it belongs to electrical machine domain, exactly relates to a high performance magnetic resistance electrical machinery, in order to solve the problem of the traditional magnetic resistance electricalmachinery existence torque pulsation large. The invention includes the stator core, the stator winding and the rotor iron core, and also includes metal thin steel plate. The invention through the method of embedding the metal thin steel plate in the partition magnetism narrow, reduced the interelectrode leak magnetism and the winding inductance, because of the even distrubtion of the magnetic flux in the stator or the rotor, avoided the partial saturation, could maintain the position angle rate that changes winding inductance along with the rotor is the constant, therefore also can reduce the torque pulsation, reduced the electrical machinery vibration and noise. The invention can enhances the electrical machinery output torque, and reduces the electrical machinery torque pulsation.
Description
Technical field
The invention belongs to machine field, be specifically related to a kind of high-performance magnetic resistance motor.
Background technology
Traditional switched reluctance machines structure as shown in Figure 1, the stator and rotor of motor are salient-pole structure.By the stator excitation winding is switched on successively, stator poles and rotor pole interact and produce torque.Owing to both do not had winding on the rotor, do not have permanent magnet, so motor be simple in structure, reliable yet.But traditional switched reluctance machines exists torque pulsation big, problems such as vibration and noise height; Simultaneously because the rotor interelectrode magnetic leakage is big, can increase winding inductance, make the Current Control response speed slow, particularly during high speed, winding current is difficult to reach desired value, and torque is reduced.
Summary of the invention
There is the big problem of torque pulsation in order to solve traditional reluctance motor, the invention provides a kind of high-performance magnetic resistance motor.
The present invention includes stator core, stator winding and rotor core, stator core and rotor core are salient-pole structure, and it also comprises sheet metal, unshakable in one's determination extremely going up radially have be parallel to each other every the narrow groove of magnetic, in the narrow groove of magnetic, be embedded with sheet metal.
The present invention is by adopting extremely going up in stator core or rotor core, radially have be parallel to each other every the narrow groove of magnetic, in the method that in the narrow groove of magnetic, embeds sheet metal, reduced interelectrode magnetic leakage and winding inductance, the output torque when having improved high-speed cruising is owing to can make magnetic flux be evenly distributed in stator or rotor pole, avoided local saturated, can keep winding inductance is constant with the rate of change of rotor position angle, therefore can reduce torque pulsation, reduces the vibration and the noise of motor.The present invention can improve the output torque of motor, reduces the torque pulsation of motor.
