摘要

PURPOSE: A stall protection circuit of an induction motor, a drive system of an induction motor, and a stall protection method of an induction motor are provided to efficiently prevent stall by considering the power factor of an induction motor and the temperature of a driver.;CONSTITUTION: A stall protection circuit of an induction motor comprises a power factor and peak detection unit(161) and an acceleration determination unit(163). The power factor and peak detection unit calculates the maximum value of phase currents supplied to an induction motor and the power factor of the induction motor. The acceleration determination unit generates a stall prevention signal for determining whether the induction motor is accelerated by comparing the calculated maximum value of the phase currents and power factor with a pre-set reference value.;COPYRIGHT KIPO 2012
