Energy conservation technique in induction motor by minimizing idle and redundant running of motor: 1) Loss of energy as the no load power drawn is approximately about 12% to 16% of rated power output in most of motors. Therefore, idle running should be avoided. 2) Unnecessary heat production at friction points such as bearings, leading to wearing of bearing. 3) Motor being highly inductive load under idle running as no real power (mechanical load) on it, the p.f. of such no-load running is low, leading to unnecessary line losses. 4) Reduction in overall system energy efficiency over period of time.
