Description
Technical field
The present invention relates to motor technology, be specifically related to a kind of transversal magnetic flux variable-reluctance permanent magnet motor.
Background technology
The structure of traditional plate linear permanent magnet synchronous motor as shown in figure 28.Motor is an integer groove structure, and promptly every extremely every phase groove number of motor is an integer, and the subject matter that integer groove structure linear permanent magnet synchronous motor exists is: the detent force that is caused by slot effect of motor is bigger on the one hand; The motor properties volume ratio is low on the other hand, and this mainly is owing to work as the pole span τ of motor
pWhen designing greatly, the conductive magnetic yoke portion of permanent magnet is thickened, thereby can increase the volume and weight of motor, and work as the pole span τ of motor
pDesign hour, can make armature core tooth pitch τ
tVery little, this can reduce the intensity of armature tooth, i.e. the tooth pitch τ of motor
tWith pole span τ
pDesign be not easy to take into account.It is long that each phase winding coil is exposed at the outer end of iron core teeth, and each phase winding coil intersects mutually, so not only wastes coil, increases copper loss, also makes the insulating process between each phase winding become complicated, the manufacturing cost of increase.In addition the permanent magnet of motor be positioned at its secondary on, when the stroke of motor was longer, making the needed iron core of motor, copper conductor or permanent magnet can increase along with stroke with being directly proportional, motor cost can correspondingly increase.
The structure of traditional multi-phase permanent synchronous machine as shown in figure 29.The armature winding of this motor is distributed winding, and the quantity of forming the required coil of winding is many, and each phase winding end of winding intersects mutually, the winding terminal minister, and copper loss is big; The winding insulation complexity, the manufacturing cost height.Owing to all have magnetic coupling between phase and phase, this can influence the control precision of electric current on the one hand because of the existence of mutual inductance; On the other hand the magnetic flux that also can produce because of the energising of each phase winding the magnetic circuit of process is long makes elementary iron loss bigger, thereby limited the further raising of electric efficiency.
It in the Chinese patent application of first to file number is the patent of invention of 200910217415.3 " interphase electromagnetic decoupling cylindrical permanent magnet linear synchronous motor ", application number is the patent of invention of 200910217413.4 " inter-phase electromagnetic decoupling flat permanent magnet synchronous straight line motor ", application number be the patent of invention of 200910217414.9 " transverse flux permanent-magnet planar motor " and " permanent magnet synchronous motor with interphase uncoupled structure " that application number is 200910217412.X though patent of invention in solve the problem of transverse magnetic flux, also exist the secondary structure complexity, reliability and the low problem of Current Control precision.
Summary of the invention
The present invention is in order to solve secondary structure complexity, reliability and the low problem of Current Control precision, and proposed a kind of transversal magnetic flux variable-reluctance permanent magnet motor.
Transversal magnetic flux variable-reluctance permanent magnet motor of the present invention is made up of primary and secondary, has air gap between the primary and secondary; Secondaryly comprise secondary iron core; Elementaryly form by at least one facies unit; Each facies unit is made up of facies unit iron core, facies unit winding and permanent magnet; Described facies unit iron core is made of the facies unit iron core that has perforation several core unit 5, described perforation is formed by the teeth groove stack of several core unit, permanent magnet is provided with on the tooth of described core unit, and it is opposite to be positioned at the direction in the magnetic field that permanent magnet produced on the adjacent iron core unit tooth; Coil is by the perforation coiled one phase facies unit winding of facies unit iron core.
The permanent magnet of transversal magnetic flux variable-reluctance permanent magnet motor of the present invention is positioned on the tooth of core unit, and therefore secondary is simple in structure, the reliability height.When motor during for moving elementary mode, the motor permanent magnet consumption is few, and cost is low, especially in long stroke motion system; When motor during for moving secondary mode, secondary structure is simple, the reliability height, and secondary is in light weight, and the dynamic characteristic of system is good.Elementary tooth pitch and secondary pole span can be according to system's needs, design arbitrarily.And owing to eliminated alternate magnetic coupling, shortened the magnetic circuit of winding magnetic flux, and armature core can adopt silicon steel sheet to build up, flow direction is vertical with silicon steel sheet lamination direction, so the present invention can reduce the eddy current loss of motor, the raising efficiency of motor, Current Control precision height, the reliability height of system, simple in structure, easily realize modularization.This motor both can be used as motor and had used, and also can be used as generator and used.
