Description
Technical field
The present invention relates to switch reluctance motor control method fields more particularly to a kind of circumferential axial backmixing cloth mutually to switch magnetic
Hinder motor control method.
Background technique
Current switched reluctance machines are primarily present the problem of torque pulsation and noise, and analysis has it inevitable former from structure
Cause, by taking most common 3 phase switch reluctance motor as an example, rotor with salient pole is tangential to make from active position to alignment stator salient poles position
Zero firmly is changed to from big value, radial forces change to maximum value from small value, and the variation of tangential forces amplitude is main to be influenced to turn
Square pulsation, the variation of radial forces amplitude is main to influence noise, and when special low speed, rotor with salient pole working distal tip is closer and stator
Salient pole aligned position, two kinds of active force amplitude variations are maximum at this time, maximum so as to cause pulsation and noise, it follows that from knot
The method solved the problems, such as on structure is: as allowing rotor with salient pole working distal tip separate as possible and stator salient poles aligned position, i.e., as far as possible
Shutdown angle is allowed to shift to an earlier date.There are problems that torque pulsation and noise switched reluctance machines, it is well known to pass through the increase number of phases
To improve.Current switched reluctance machines are mainly circumferential cloth phase, can theoretically have 2 phases, 3 phases, 4 phases ..., q phase, q be from
So number, 2 phase switch reluctance motors have most effect numbers of poles, and effect number of poles is the 1/2 of stator core salient pole number, but cannot be any
Position starting and positive and negative rotation, 3 phase switch reluctance motors have the function of more number of poles, and effect number of poles is stator core salient pole number
1/3, it can start at an arbitrary position and positive and negative rotation, more numbers of phases mean to act on the reduction of number of poles, motor torsion will be sacrificed
Square and efficiency, circumferential cloth mutually determines that motor cannot arbitrarily increase the number of phases, therefore the author devises circumferential axial backmixing cloth and mutually opens
Reluctance motor is closed, a kind of circumferential axial backmixing cloth phase switch reluctance as described in number of patent application is " CN 2016204654682 "
Motor can be implemented as multiplication phase, but number of phases mistake by multiple q phase stator core arranged in dislocation or rotor core arranged in dislocation
