Temperature calculation system of motor using thermal equivalent circuit
A temperature calculation system includes a yoke disposed along an inner circumference, first and second teeth arranged on an inner circumference surface of the yoke while having an interval set in a circumference direction, and a coil member formed between the first and second teeth and including a plurality of coils, forms a thermal equivalent circuit of the coil member, and calculates a temperature of a set portion of the coil member. An outer circumference surface temperature and an inner circumference surface temperature of the coil member are calculated by using radial conduction resistance using a temperature of an inner one side of the coil member. An average temperature of the coil member is calculated by using compensation resistance from the temperature of the inner one side of the coil member, thermal capacity of the coil member, and a heating amount of the coils formed in the coil member.
