Kind Code:
A
Abstract:
To obtain a motor drive unit which reduces both physical quantity such as vibration or noise, and power consumption of a motor (including an inverter), or minimizes one of them on condition that either of them is not larger than a threshold.
A phase correction means 33 selects a phase correction pattern whose current value [A] is minimum from among remaining phase correction patterns, and sets a phase correction amount [degree] in the phase correction pattern as a phase correction amount to be added to a current phase 18.
