DC motor with half wave rectified source
This is a throttling valve for the aux-feedwater system that has been operating in the plant for 20 yrs. The field is full-wave rectified and always energized. The armature resistance is 5 ohms & inductance is 12 mH. The SCRs are in parallel with a 47 ohm resistor and a 0.1 F capacior. The...- Microfarad

DC motor with half wave rectified source
I am evaluating a shunt dc motor to determine if it will produce the min. torque required for my valves. It's ratings are .361 hp, 95 arm.volts, 4.7 arm.amps. It's being supplied by 104 Vac source (120V under min. volt conditions) that is half-wave rectified (through SCRs) by a Modutronic 10A...- Microfarad
