Control of the Saturistor Motor

The performance of the saturistor motor is improved by the addition of capacitors in the secondary circuit. The ac performance on run-up is changed considerably with increased torque production,reduced supply current and a power factor nearer to unity. DC dynamic braking is also influenced to the extent of increased braking torque, and reduced run-down times under comparable braking conditions. Braking using capacitor excitation is shown to be improved by the presence of saturistors. Analysis of the various modes of operation is discussed with acceptable prediction of the experimental characteristics.
