Thyristor & Motor Control

Thyristor & Motor Control

70-003

This Trainer comprises a Firing & Bridges panel, a Motor Control Circuits panel, a Three Phase Supply Panel, SCR & Diodes Panel, and all of the loads, instrumentation, etc to enable the study of the principles of Single and Three Phase rectification applied to passive loads and to apply these thyristor circuits to the control of dc motors. In addition to all of the work covered by the Thyristor Control Principles trainer, the Thyristor and Motor Control trainer enables the study of dc motor control. Motor speed and current control circuits may be investigated with various types of feedback, including PI control and 4 Quadrant control. Zero crossing and burst firing circuits are also covered.
