| Summary: | 1. Field of the Invention
An object of the present invention is to provide a motor control system comprising an R/D converter which is capable of outputting a good phase signal without being affected by the switching noise due to a PWM signal of an inverter and a motor control method.A motor control system comprising a motor having a resolver as a rotary sensor; an inverter for driving the motor; and a control unit for controlling the inverter, the control unit executing phase calculation processing based on a phase signal which is an output of the resolver converted by an R/D converter calculating a voltage reference based on a current reference and a current value of the motor detected by a current sensor generating a PWM signal for controlling the inverter based on the voltage reference, wherein a PWM synchronism signal in synchronism with the PWM signal is generated in the control unit, and the R/D converter is driven using the PWM synchronism signal. |
