Variable speed motor drive system

摘要: A motor drive system which utilizes the relatively poor storage time or turn-off of Darlington pair power transistors have typically been used as driver elements in inverter applications. It primarily finds use multiphase systems, such six step three phase inverter. The long provides constant collector current to without need for additional circuitry provide base load. An circuit automatically and dynamically tailors torque load requirements minimize unnecessary electrial energy.
