摘要 |
A motor driving device of the present invention includes: a driver that receives supply of a power supply voltage to apply a plurality of phase voltages to a motor; a voltage-division phase voltage generation portion that divides each of the phase voltages to generate a plurality of voltage-division phase voltages; a neutral point voltage generation portion that combines and divides the phase voltages to generate a neutral point voltage; a selector that outputs any one of the voltage-division phase voltages as a selection voltage-division phase voltage; a comparator that compares the selection voltage-division phase voltage and the neutral point voltage to generate a comparison signal; and a controller that generates a selection control signal of the selector and an energization control signal of the driver according to the comparison signal. |
