Abstract

The invention discloses a switch reluctance motor with a hybrid air gap modular stator, and belongs to the field of switch reluctance motors. The motor structure comprises modular stator cores, stator coils and a rotor, wherein each modular stator core is provided with three magnetic poles, namely an axial upper magnetic pole, an axial lower magnetic pole and a radial magnetic pole; the axial upper magnetic pole and the axial lower magnetic pole of each modular stator core are opposite to the rotor in an axial direction to form an axial upper air gap and an axial lower air gap; the radial magnetic pole is opposite to the rotor in a radial direction to form a radial air gap; each stator coil is wound on the radial magnetic pole of each modularized stator core; the two opposite coils are connected in series or parallel to form a phase winding; and the three magnetic poles of each stator core respectively generate action force on the rotor through the three air gaps so as to drag the rotor to operate. The switch reluctance motor has large power output and good fault tolerance, and has wide application prospect in driving systems of electromobiles and the like.

Technical field
The present invention relates to a kind of switch reluctance motor with hybrid air gap modular stator, belong to the switched reluctance machines field of electric machinery.
Background technology
Common Stators for Switched Reluctance Motors and rotor are salient-pole structure, and stator core tooth wherein is wound with concentrated winding on extremely, and rotor is simple solid lamination, no permanent magnetic material and winding.This simple in structure firm, reliability and durability, and switched Reluctance Motor Control is flexible, fault-tolerant ability is strong, has advantages such as High Temperature And Velocity adaptability, is fit to be applied to fields such as advanced aircraft, automobile and naval vessel.
But the air gap between the rotor of regular tap reluctance motor generally is radial air gap, when the axial length of motor more in short-term because stator only produces active force by radial air gap to rotor, the output torque of motor is less.
In order further to increase the fault freedom of switched reluctance machines, launched research at present both at home and abroad simultaneously to the modular stator switched reluctance machines.
Summary of the invention
The technical problem to be solved in the present invention be propose a kind ofly to export that torque is big, zmodem, the switch reluctance motor with hybrid air gap modular stator that is easy to start.
Switch reluctance motor with hybrid air gap modular stator of the present invention, comprise the modular stator iron core, stator line bag and rotor, the modular stator iron core has three magnetic poles, be respectively and axially go up magnetic pole, axial lower magnetic pole and magnet radial poles, the modular stator iron core axially go up magnetic pole and axially lower magnetic pole all from axially go up and rotor over against, form and axially go up air gap and axial air gap down, the magnet radial poles of modular stator iron core from the footpath upwards with rotor over against, form radial air gap, all twine a stator line bag on the magnet radial poles of each modular stator iron core, two relative stator line bag serial or parallel connections that are wrapped on the modular stator iron core are a phase winding.
Mixing air gap switched reluctance machines of the present invention has following beneficial effect:
1, each modular stator iron core can wind the line separately, and winding operation is easy to automation, and can guarantee the consistency of each stator winding, thereby ensures motor properties;
2, saved the radially yoke part of regular tap reluctance motor stator,, provided cost savings so switch reluctance motor with hybrid air gap modular stator core material consumption of the present invention is few;
3, the alternate magnetic circuit of motor and circuit are almost completely independent, and isolating power is strong, and fault freedom is very good;
4, the mutual balance of the axial component of pole pair rotor suction up and down is so the structure of switched reluctance machines of the present invention has been eliminated the unbalanced shortcoming of conventional axial air gap motor unilateral magnetic force;
5, because three pole pair rotors of each modular stator produce active force,, start easily so switched reluctance machines of the present invention is exerted oneself greatly;
To sum up, switched reluctance machines of the present invention has broad application prospects in various drive systems such as electric motor car.
