light and ■ blocked rotor tests. RUNNING LIGHT TEST. The motor is allowed to run at no load, and is supplied with variousvoltages at nofcmal frequency, ranging from 25 per cent above normal to a value atwhich the motor will just continue running. Beginning with the highest value ofvoltage, current… … Fig. 1. curves are plotted between volts and watts and between volts and amperes. Thelosses due to hysteresis at constant frequency vary with the flux density and there-fore with the counter e.m.f. The copper losses with the motor running light maybe calculated from primary resistance and current,…
