Summary of the invention
The utility model provides a kind of switching magnetic-resistance permanent magnetism salient poles rotor motors in order to solve the existing problem that the Stators for Switched Reluctance Motors winding utilization is low, rotor torque is less and specific volume power is less.
The utility model is to adopt following technical scheme to realize: switching magnetic-resistance permanent magnetism salient poles rotor motors comprises stator and rotor; Described stator comprises stator core, be fixed in several magnetic pole of the stator on the stator core and the stator winding on each magnetic pole of the stator; Described rotor comprises rotor core, is fixed in several rotor magnetic poles on the rotor core; Each rotor magnetic pole is permanent magnetism magnetic pole.
During work, the magnetic field that stator winding electrifying produces produces repulsive force and attraction simultaneously to each permanent magnetism magnetic pole of rotor.Under the acting in conjunction of repulsive force and attraction, rotor produces turning moment.Based on said process, compare with existing switched reluctance machines, switching magnetic-resistance permanent magnetism salient poles rotor motors Effective Raise described in the utility model the stator winding utilance, and then effectively increased rotor torque, and effectively increased specific volume power, solved thus the problem that existing Stators for Switched Reluctance Motors winding utilization is low, rotor torque is less and specific volume power is less.
The utility model efficiently solves the existing problem that the Stators for Switched Reluctance Motors winding utilization is low, rotor torque is less and specific volume power is less, is applicable to coal mine equipment.
