Motor driving module, operating method for the same, and brushless DC motor system
Abstract:
The inventive concept provides a motor driving module, a operating method for the same, and a Brush less Direct Current (BLDC) motor system. The motor driving module is provided which comprises a motor driving unit configured to output a plurality of switching signals based on a plurality of position signals and a control signal; and a Pulse Width Modulation (PWM) inverter configured to output 3-phase voltages based on the plurality of switching signals outputted from the motor driving unit, wherein the motor driving unit comprises; a correction circuit configured to detect an error of the plurality of position signals to output a compensation signal based on the detecting result; and a control circuit configured to output the plurality of switching signals based on the compensation signal and the control signal, wherein the plurality of position signals indicate a position of a rotor in an external motor.
