Abstract
A composite excitation switch magnetic resistance motor is composed of a stator, a rotor, an excitation winding and a permanent magnet among which, the magnet is inserted in each wide slot, N and S poles of which are connected on two vertical walls of the slot, an excited winding is winded on the root of each pole body of the stator sleeved on the rotor with an air gap between surfaces of the stator internal post and the rotor outer post and the stator axial lead is coincident with that of the rotor.
Description
Technical field: the present invention relates to a kind of switch motor, specifically is the switched reluctance motor of a kind of electromagnetism and permanent magnetism composite excitation.
Background technology: stator, the rotor of existing switched reluctance machines are salient-pole structure.By the stator excitation winding is switched on successively, the electromagnetic force between stator poles and the rotor pole interacts and produces torque.Owing to have only excitation winding on the stator, and do not have there is not winding on permanent magnet and the rotor, also do not have permanent magnet, so motor is simple in structure, reliable.But all do not use permanent magnet just because of stator, rotor,, must use the bigger motor of volume, need big exciting power simultaneously, so just limited the motor properties volume ratio, strengthened the cost of drive system again in order to obtain big output torque.
Summary of the invention: the purpose of this invention is to provide a kind of Hybrid Excitation Switched Reluctance Motor.The present invention can solve the existing low shortcoming of Switched Reluctance Motor volume ratio.The present invention is made up of stator 1, rotor 2, excitation winding 3, permanent magnet 4; Stator 1 is the cylindrical sleeve that permeability magnetic material is made, have a plurality of sipes 1-1 and narrow groove 1-2 on its inner cylinder face, the axis parallel of the length direction of sipes 1-1 and narrow groove 1-2 and stator 1 also runs through the inner periphery of stator 1, sipes 1-1 and narrow groove 1-2 space are evenly distributed, and sipes 1-1 equates with pole body 1-3 thickness between the narrow groove 1-2; Rotor 2 is cylinders that permeability magnetic material is made, and evenly has a plurality of groove 2-1 on the external cylindrical surface of rotor 2, and the center of rotation line parallel of the length direction of groove 2-1 and rotor 2 also runs through the outer cylinder surface of rotor 2; Permanent magnet 4 is embedded among each sipes 1-1, and the N utmost point of permanent magnet 4 is connected respectively on two perpendicular walls of sipes 1-1 with the S utmost point; All be wound with excitation winding 3 on the root of each pole body 1-3 in the stator 1, stator 1 is enclosed within the outside of rotor 2, and is provided with air gap 5 between the external cylindrical surface of the inner cylinder face that makes stator 1 and rotor 2, and the axial line of while stator 1 and the rotational axis line of rotor 2 coincide.Operation principle: when excitation winding 3 no powers, the magnetic line of force of permanent magnet 4 does not pass through air gap 5, but passes through pole body 1-3, the yoke portion closure of stator 1; When excitation winding 3 was alived, the magnetic line of force path of the path of its electric excitation magnetic line of force and permanent magnet 4 formed parallel circuits, and two magnetic fields form flux circuit by air gap 5, rotor 2.On-off action by electric excitation magnetic potential (excitation winding 3 electric currents logical and disconnected) is controlled the path and the size of magnetic flux power of the magnetic line of force of permanent magnet 4, realizes that the torque of motor is controlled.The present invention has very high ratio of performance and volume and performance weight ratio, can use as motor, also can use its easy care simple in structure as generator.
