Title: Method of controlling brushless permanent-magnet motor
Inventor: ZHENG LIBO
IPC: H02P6/18
Filed: 2017-04-26
Abstract: PROBLEM TO BE SOLVED: To commutate phase windings of a brushless permanent-magnet motor at correct times.SOLUTION: A method of controlling a brushless permanent-magnet motor includes sequentially exciting and freewheeling a phase winding of the motor. Here, the phase winding is freewheeled when the phase current exceeds an upper threshold. The method further includes either (i) measuring a parameter that corresponds to the magnitude of the phase current during or at the end of the freewheeling when the phase winding is freewheeled for a fixed period of time, or (ii) measuring a parameter that corresponds to either the time interval between the start and the end of the freewheeling or the time interval between the start and the end of the excitation when the phase winding is freewheeled until the phase current falls below a lower threshold. The measured parameter is then compared against a saturation threshold; it is determined that a rotor is at a predetermined position when the measured parameter is less than the saturation threshold; and, in response thereto, the phase winding is commutated after a commutation period has elapsed.SELECTED DRAWING: Figure 3
