JDCX motors have been especially designed for frequently started machinery. The starting current of general induction motors is 5-7 times of its rated current. As a result of over-current and heat, electric motors are likely to be ruined over time. However, this motor is free of such problems due to its special design. This motor series is composed of two types: double-speed and triple-speed motors. They are applicable to frequent started devices, wheel-shaping machines in the rubber industry, for example. The rated voltage is 380V; the rated frequency is 50Hz; the insulation grade is class B. (Please indicate in your order if you have special request in voltage or frequency)
