The Three Phase Rheostat Unit includes three adjustable single-phase rheostats mounted on the same shaft and connected in wye. The main function of rheostats in a control system is to adjust the current in a rotating machine winding when voltage drop is needed. The three-phase rheostat is very useful for wound motor starting. By varying the external resistors in the rotor circuit, the motor starting torque and current can be adjusted to the required value. This also allows manual control of the motor speed with load. It can be used for wound rotor motor applications. Connections can be made between the three-phase power supply and other components in the circuit through 4mm φ standard color-coded safety sockets using banana plug jumper leads. Specifications and/or diagrams are silk-screened on the back of a clear-plastic front panel for ease of identification. The trainer is protected by a either a diode or thermal-magnetic circuit breaker. Included in the Rotating Machines Trainer (50016) for 1/3 hp - 250 W. Requires a 120V 60Hz circuit.

These are wonderful trainers! With the ability to remote control them with a laptop, real life situations can be simulated (read: intermittent faults) and it also helps with so many different areas of expertise! San Jacinto College has these trainers and couldn't be more satisfied. Well done, ConsuLab!J.P. Goins, GM ASEP instructor, San Jacinto College
