Gerald Reiner,Werner Jammerneggown. Although some losses do occur in the conversion process, the majority of the electrical energy which enters the motor is converted to mechanical form and delivered to the load. Consider Fig. 2.1 which shows a 50-hp motor driving a pump of equivalent rating. The power distribution is shown in th

Inhaltliche und begriffliche Grundlagen,, electronically controlled starting is being used. When rated voltage is applied to a motor at standstill, the inrush current is several times the rated load current. For motors in the medium ac size, the starting torque accompanying this high inrush current generally exceeds 100% of full-load torq
