WebThe choice of PTC thermistor depends on the insulation rating of the motor. The Curie temperature of the PTC thermistor is usually selected in a range of about 40 ° C lower than the limit temperature corresponding to the motor insulation level. For example, for a B1 insulated motor, the limit temperature is 130 ° C, and a PTC thermistor with ... WebThe PTC sensors should be connected in series to detect the temperature of all phases’ windings. A drive is supposed to shut off power to the motor when a winding’s temperature reaches its maximum permitted value as a result of these temperature sensors.
