Abstract :
Opportunities to improve motor efficiency by reducing the present restrictions on the motor starting current are identified. The existing National Electrical Manufacturer´s Association (NEMA) standards are reviewed, and a new standard is recommended. The impact on motor operating temperature and power factor is discussed. In those cases where increased starting current is prohibitive, alternative starting methods are given
