Overtemperature Protection Device For Motor
Abstract: s12fProvided is an overtemperature protection device for a motor applicable to a railway vehicle drive system which operates a plurality of motors in parallel by using one or more inverter devices. The overtemperature protection device is provided with a control device (14) for controlling the operation of an inverter device (10) and a protection device (20) for detecting an overtemperature that may occur in motors (12a 12b) on the basis of a frequency signal (f) containing frequency information when the inverter device (10) maintains a constant ratio of voltage to frequency with respect to the motors (12a 12b) and on the basis of currents (I I) of at least one phase which flow in the motors (12a 12b) while generating an overtemperature protection signal (T) for protecting the motors (12a 12b) from the overtemperature and outputting the signal to the control device (14).
