Voltage controlled asynchronous electric drive
Authors:
Abstract
Asynchronous electric drives of many machines and mechanisms of mining industry (for example, belt conveyors) operate with average load factor less than unity (0.4-0.6). Under these conditions, the weighted average power factor and efficiency of induction motors are much lower than the maximum possible values, resulting in poor motor utilization and excessive power consumption ...
