Description
Technical field
The utility model relates to a kind of motor, is specifically related to the improvement that stator and rotor structure to motor carry out.
Background technology
The field that motor (comprising motor and generator) is used is very extensive, therefore improves efficiency of motor and has great significance in the application of some occasion for energy savings and motor.Traditional motor, usually form by a stator and a rotor, with the induction machine is example, stator is made up of stator core and stator winding, stator core is overlapped into cylindric by silicon steel sheet, embed in the shell of motor, be evenly distributed with a plurality of grooves that be arranged in parallel with motor shaft on the stator core, be provided with stator winding in the groove; Rotor is positioned at the cylindrical cavity of stator, and is separated with air gap between stator, and rotor core is contained on the motor shaft, and the rotor core surface is embedded with the copper filler rod parallel with motor shaft, and is connected by short-circuited conducting sleeve, and the motor shaft two ends are connected with the both sides end cap of shell by bearing.Behind stator winding electrifying, around stator, form rotating magnetic field, rotor goes out electric current at copper filler rod internal induction under the effect of rotating magnetic field, make rotor rotated by the effect of stator field, drives motor shaft and rotates output.This structure of being made up of the rotor of columnar stator in periphery and interior cylindrical, the standard that has become motor is formed structure, all extensively adopts in electromagnetic type, induction type and constant magnetic motor.
We are the relation that example is analyzed its structure and power with the motor.
The principal element of decision motor work done (electric energy is converted into mechanical energy) can be expressed with formula F=B * I * L simply,
In the formula: F---the electromagnetic force that current carrying conductor is suffered,
B---the magnetic flux density of certain point in the magnetic field,
I---the electric current that passes through in the stressed lead,
L---the conductor length vertical with magnetic direction.
Therefore, the ability of work done be increased, the long-pending of B * I * L must be increased.
For the motor in the said structure, its magnetic field B can be thought by stator decision, B=μ NI/L, magnetic conductance μ is wherein restricted by the stator core material, N is the number of turn of stator coil, and I is the size of current by this coil, thereby the size of magnetic field B is restricted, for the single magnetic pole of stator, increasing progressively of B value can only restrict in certain scope.
I * L is main relevant with the rotor of motor, is example with the inductor motor, and I depends on e (induced electromotive force), e=B * L * V, under the condition of determining, B, V are that (in the alternating current machine, V is determined by electric frequency constant, B is determined by the magnetic conductance μ and the physical dimension of material), have only increase L, promptly increase the radical of lead or increase the length of every lead, increase the long-pending of I * L, like this, certainly will increase the surface area (S) of rotor.
As seen, under the structure of this single stator and rotor, increase power of motor, the one, increase the magnetic conductance μ of material, certainly will increase the cost of motor so greatly; Be the work area that increases stator, rotor, this can cause the increase of motor volume.
Particularly, under the situation that material is determined, the way that increases work area exists bigger problem, that is: because rotor volume increases, the quality of rotor is increased, and has increased the difficulty of starting; Simultaneously, after rotor volume increased, the length of magnetic path that rotor is passed through in the magnetic field that makes stator produce increased, thereby can cause the reduction of magnetic flux, can influence the increase of power of motor conversely again.
Therefore, must the stator and rotor sructure of motor be improved, if can increase power of motor not increasing or reduce to power up under the long-pending situation of body, also promptly under situation, reduce the volume and weight of motor with constant power output, will produce revolutionary impact to the application of motor.
