Abstract :
The author identifies opportunities to obtain improved motor efficiency by reducing the present restrictions on the motor starting current. The existing US National Electrical Manufacturer´s Association (NEMA) standards are reviewed and recommendations are given for a new standard. 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.<>
