Abstract

A power supply apparatus (100), comprising a motor (MOT1), a circuit measurer (120), a temperature sensor (130) and a computing circuit (140). The circuit measurer (120) is configured to measure the operating frequency of the motor (MOT1) and a current that flows into the motor (MOT1) via a busbar. The temperature sensor (130) is configured to measure an initial temperature of a stator (MS_U) of the motor (MOT1) in an initial state. The computation circuit (140) is coupled to the circuit measurer (120) and the temperature sensor (130). The computation circuit (140) is configured to: execute a power model, so as to calculate a first transient power of the motor (MOT1) on the basis of the initial temperature, the operating frequency and the current; and execute a thermal model, so as to calculate a first transient ideal temperature of the motor (MOT1) on the basis of the first transient power. The power supply apparatus (100) measures the operating frequency and current of the motor (MOT1), so as to calculate a transient temperature of the stator (MS_U) of the motor (MOT1) in real time.
