Abstract: The present disclosure relates to an apparatus and method for estimating a temperature of a motor using a Hall sensor. The method includes detecting, at a digital Hall sensor, a position of a rotor included in a motor and outputting an on signal in an operating period and an off signal in a release period according to a relative position of the rotor, calculating, at a temperature determining module, a difference between duration of the operating period and duration of the release period according to an output waveform of the digital Hall sensor, and then determining, at the temperature determining module, a temperature of the motor with reference to a temperature corresponding to the duration difference. Accordingly, it is possible to estimate the internal temperature of a motor without installing a temperature sensor in the motor, to maintain a small size of the motor, and to reduce production costs.
