Abstract :
Description of a drive that uses saturable reactors and a wound rotor motor to provide adjustable constant speed performance comparable to d-c variable voltage drives. A line contactor is used to connect the system to the power line. All regulating components are static. Motor currents are controlled in all three phases for motor heating.
