10. ENERGY EFFICIENT TECHNOLOGIES IN ELECTRICAL SYSTEMS
www.beeindia.gov.inIn polyphase induction motors, slip is a measure of motor winding losses. The lower the slip, the higher the efficiency. Less slippage in energy efficient motors results in speeds about 1% faster than in standard counterparts. Starting torque for efficient motors may be lower than for …
