METHOD FOR EFFECTING THE POWER-OPTIMAL CONTROL OF BLDC MOTORS |
摘要 |
The method involves continuously updating commutation time points by measuring the time difference between two immediately successive null crossings (TN1,TN2) of the induced voltage in the non-current-carrying motor coil and commutating the next motor phase after half the determine time difference has elapsed. This is continued, using a switching algorithm for all phases. Independent claims are also included for the following: (a) a circuit arrangement for power-optimal control of brushless DC motors (b) a method of starting a BDLC motor (c) and a method of fault-tolerant power-optimal operation of a BDLC motor. |
