Abstract:
A motor driving module is provided which includes a motor driving unit configured to control a PWM inverter on the basis of positional information and a control signal; a PWM inverter configured to output three-phase voltages on the basis of DC power according to control of the motor driving unit; a phase voltage estimating unit configured to output three-phase estimated voltages on the basis of the positional information, the DC power, and a voltage modulation index; and a position detecting unit configured to output the positional information on the basis of the three-phase estimated voltages, wherein the positional information is on an external motor that operates on the basis of the three-phase voltages.
