Apparatus and method for driving the multiphase motor using the magnetic pole position detector
摘要:
A motor driving apparatus includes a motor driver which includes a parallel circuit in which a plurality of series circuits are connected in parallel. Each of the plurality of series circuits has a high side switching device and a low side switching device connected in series. A voltage detector detects a voltage at a neutral point of the multiphase motor and outputs the detected voltage as a first detection signal. A timing detector detects a timing at which a voltage of the first detection signal equals to a reference voltage, and outputs the detected timing as a second detection signal which is used to generate a plurality of driving signals for driving switching devices in the parallel circuit.
