Recently, a kind of novel permanent-magnetic-switch flux linkage motor quilt research more and more widely.In this electric rotating machine, permanent magnet and winding all are placed in stator side, and rotor only is made of core lamination.Characteristics such as permanent-magnetic-switch flux linkage motor shows efficiently equally, high power density, high reliability, and be easy to dispel the heat, have good overload capacity.Linear electric motors form correspondingly also is suggested, and in the permanent magnet switch magnetic linkage straight line motor, permanent magnet and winding place the mover side, and stator only is made of iron core.Therefore under long stroke situation, required permanent magnet and winding all seldom, cost is very low.But in traditional permanent magnet switch magnetic linkage straight line motor, brow leakage is serious, and the permanent magnet utilance is low, and it is lower to place two groups of winding copper factors in a groove.
Summary of the invention
The purpose of this utility model is to propose a kind of modularization error-tolerance type permanent magnet switch magnetic linkage straight line motor, improves the permanent magnet utilance and possesses suitable fault-tolerant ability, is fit to be applied to fields such as traffic traction, industrial transmission.
The disclosed modularization error-tolerance type permanent magnet switch magnetic linkage straight line motor of the utility model, comprise stator and mover, stator is Alveolus type flat board or the cylinder that constitutes unshakable in one's determination, mover is spaced the flat board or the cylinder of formation for several modules and magnetoresistive bit, each module comprises two inverted " U " shape iron cores, be interposed in two " U " shape iron cores middle permanent magnet and threephase armature winding, two " U " limit unshakable in one's determination that inserts and puts permanent magnet forms armature tooth, two " U " limits unshakable in one's determination that insert and put magnetoresistive bit form auxiliary tooth, the threephase armature winding is on armature tooth, on the auxiliary tooth not around winding, the permanent magnet N utmost point of adjacent block, the S utmost point is alternately arranged.
Above-mentioned stator core is formed by silicon steel plate packing.The opening of said " U " shape iron core is standard-sized sheet mouth or half opening; Form by silicon steel plate packing.
In the utility model, said permanent magnet is neodymium iron boron, SmCo or the ferrite of parallel magnetization.Said threephase armature winding is for concentrating winding, fractional slot winding or distributed winding.Said magnetoresistive bit is plastics, aluminium or pottery.
Because the saliency that stator tooth forms, along with the change of rotor position, the permanent magnet excitation magnetic linkage generation bipolarity of armature winding institute hinge changes, and induction produces back-emf thus, can drive the mover rectilinear motion if apply suitable electric current to armature winding.Be added to voltage swing and frequency on the armature winding by control, the speed of scalable motor then is fit to the needs of different occasions.
The beneficial effects of the utility model:
1. modularization error-tolerance type permanent magnet switch magnetic linkage straight line motor has the advantage of permanent-magnetic switching flux linkage electric rotating machine and linear electric motors.
2. permanent magnet and threephase armature winding all place the short mover side of length, and stator only is made of core lamination, and is with low cost, have great cost advantage during particularly long stroke.
3. modularized design is convenient for assembly, is easy to low-cost production in enormous quantities the in enormous quantities.
4. the threephase armature winding is intervally arranged, between the winding mutual inductance very little, realized the electromagnetic isolated between the winding, have higher fault freedom.
5. auxiliary tooth plays the isolated effect of physics to the threephase armature winding, further improves the fault freedom of motor.
