Today is to introduce the circulation of the brushless motor controller, want to know and small make up together and see it. 1 motor, brushless motor controller of the air gap magnetic induction intensity along the air gap according to the sine distribution; 2, winding current, the current generated by the magnetic flux on the impact of air gap is ignored; 3, the control circuit in the switch state work, the pressure drop of the power transistor to a constant value; 4, the winding is symmetrical, the corresponding circuit is completely consistent, the corresponding electrical time constant is neglected; 5, position sensor and control circuit power consumption is neglected. The relevant knowledge about the brushless motor controller, small make up is introduced here, hope to be able to help you.
