Description

A kind of axial magnetic flux two-phase doubly salient permanent magnet motor
Technical field
The present invention relates to a kind of motor, specifically a kind of axial magnetic flux two-phase doubly salient permanent magnet motor belongs to motor technology Field.
Background technology
Double salient-pole electric machine is a kind of motor of the new structure being suggested the 1950's, into the nineties after obtain people Extensive concern and further investigation, it has the advantages that firm, easily manufactured simple structure, reliable operation, easy to maintain, Wind-power electricity generation occasion has good application prospect.
Double salient-pole electric machine belongs to variable reluctance motor, and variable reluctance motor includes two kinds of unilateral salient pole and bilateral salient pole, in order to obtain Maximum magnetic resistance maxima and minima ratio, and preferably energy converting between mechanical characteristic are obtained, double salient-pole electric machine is received and ground Study carefully the more pro-gazes of personnel.Typical variable reluctance motor using magnetic resistance, magnetic flux always to the small Route Set of magnetic resistance in, as During electric motor operation, the stator winding of energization attracts ferromagnetic rotor with magnetic force, magnetic force is produced tangential component, that is, it is right to produce The torque of rotor.The power-up sequence of stator according to corresponding to the rotor-position that position sensor is detected most beneficial for rotor That phase stator of rotational torque forward is produced to be powered, rotor is turned after turning over certain angle by next generation most beneficial for rotor The one of square is mutually powered.Control system constantly changes the energization phase sequence of stator winding, rotor is persistently rotated to a direction.
