Parameter known to these is adjusted in width etc., you can flexibly realizes the operating status control of the motor.In terms of comprehensive, motor
Control mode there are three types of：(PWM), Current cut control (CCC) and Angle-domain imaging (APC) known to pulsewidth modulation.In order to
The motor external characteristics for realizing requirement carries out the different switchings for understanding pattern in different velocity intervals, to reach preferable real-time
Control effect.It is generally connected using the half period in low speed, in conjunction with Current cut control, it can be achieved that the permanent torque control of motor；
In high speed then mainly use Angle-domain imaging, at this moment in order to promote electric current accelerate rise, it is necessary in advance turn-on angle θon；In order to
Afterflow is avoided to enter inductance descending area and generate braking moment, it is necessary to reduce shutdown angle θoff, to realize the invariable power control of motor
System.
