Description

Magnetic flux switching type transverse magnetic flux high-speed permanent magnet motor
Technical field
The invention belongs to field of motor manufacturing, and in particular to a kind of magnetic flux switching type transverse magnetic flux high-speed permanent magnet motor.
Background technology
High-speed electric expreess locomotive typically refers to the motor that maximum speed is more than 10000r/min.High-speed electric expreess locomotive centrifugal compressor, The fields such as the driving motor of hybrid power or pure electric automobile, high speed machining, aero dynamo, high-speed engine have wide General, important use.They have the following advantages：Due to rotating speed height, so power of motor density is high, and volume is much smaller than common electricity Machine；It can be connected directly with prime mover, eliminate traditional deceleration mechanism, transmission efficiency, noise is small；High-speed electric expreess locomotive rotary inertia Small, dynamic response is fast.
There is also many technical problems for existing radial flux high-speed electric expreess locomotive.
First, in existing radial flux motors structure, the slot where teeth portion and armature winding that magnetic flux passes through accounts for same Ring cross-section, plane where the magnetic line of force are parallel to the direction of rotation of motor, and sectional area and the teeth portion sectional area of slot condition each other.Such as Fruit needs to flow through larger electric current, it is necessary to which larger coil section product, the sectional area of tooth is just affected, and (saturation can make Magnetic flux reduces)；Vice versa.If tooth sectional area and slot cross-section accumulate while increasing, the radius of motor is necessarily will increase, electricity is made The power and torque density of machine reduce.Innovation outlet is to select the electromagnetic structure of transverse magnetic flux.In transverse flux motor, because It detaching with circuit for magnetic circuit, and is mutually perpendicular in space, the size of iron core and winding can be adjusted independently, and design freedom is big, Power of motor and torque density can be effectively improved, multiphase easy to implement, multipole are to table structure.
Existing transverse flux permanent magnetic motor, two adjacent groups rotor core only correspond to one group of stator core, the space of magnetic flux Utilization rate is low.In the design scheme of Chinese patent CN201010100924, rotor core is realized with the mode that magnetic flux switches It is one-to-one with stator core, improve the space availability ratio of magnetic flux.But " rotor core (4) both sides are respectively embedded into one block of permanent magnetism Body (2) (3) ", that is, correspond to a stator core, and this 2 pieces with a rotor core comprising 2 pieces of permanent magnets Permanent magnet is to take turns to operate, the utilization rate of permanent magnet or relatively low.
Second, the flux density value B in the power density and electric machine iron core of motormIt is directly proportional to the product of electromagnetic frequency f, But by soft magnetic materials saturation induction density BsLimitation, to increase substantially the power density of motor must improve motor Frequency f.However, the total losses of electric machine iron core are again directly proportional to 1.3~1.5 powers of frequency.When motor working frequency from 50Hz is increased to 500Hz, it is assumed that flux density value BmConstant, the iron loss of motor does not increase by 10 times, increases more than 200 times. Therefore, the loss of silicon steel electric machine iron core will become very serious, cause efficiency to be remarkably decreased, or even motor overheating is caused to damage. For working frequency between the motor of hundreds to thousands Hz, silicon steel is replaced using Fe-based amorphous alloy, is used as electric machine iron core, for It reduces motor iron loss and iron core temperature liter is significant.The Fe-based amorphous alloy also magnetic conductivity with several times of silicon steel, can be very big The exciting current of motor is reduced in degree, and then reduces the copper loss of motor.
It is worldwide a challenge problem currently, Fe-based amorphous alloy is used as electric machine iron core.Difficult point exists In iron-based amorphous alloy ribbon material thickness：25~30 microns, Vickers hardness：900kg/mm2, Curie temperature：415 DEG C, after heat treatment Non-crystaline amorphous metal laminated core may embrittlement.To non-crystaline amorphous metal laminated core, it is difficult to processed with conventional machine cut technique, Also high current high-temperature soldering can not be carried out.Currently, iron-based amorphous alloy ribbon material maximum width is 213mm.Such strip width, For needing the existing radial flux motors using globality, large area punching band making iron core, in addition to small, micromotor Outside, medium-sized or above motor can not use at all.But for using for discrete, small size iron core transverse flux motor, in, Greatly, huge motor is all applicable in very much.
Third, when the working frequency of motor reaches hundreds of Hz or more, the kelvin effect of machine winding conducting wire will become very Seriously, if using common electromagnetic wire, the copper loss of motor will be substantially increased.Using high frequency profit magnet-wire (by the paint of diameter 0.1mm 4~25000 strands of envelope curve is twisted), when operating in a high frequency, it can substantially reduce skin effect of line, copper olse is greatly reduced.
4th, it is square directly proportional due to centrifugal force and the linear velocity on high speed rotor of motor, the stator of high-speed electric expreess locomotive and Rotor core requires very high mechanical strength.When linear velocity reaches 200m/s or more, conventional lamination armature is difficult to bear The centrifugal force that high speed rotation generates needs to use high intensity lamination armature.Unfortunately, Fe-based amorphous alloy strip system is used merely Make motor stator or rotor core, mechanical strength is far below silicon steel laminations iron core.The outlet solved the problems, such as is, silicon steel is folded The argon arc welding technology of piece combines with the riveting of non-crystaline amorphous metal lamination, dipping, curing technology, creates novel high-strength lamination Stator and rotor core.
