| SPEED CONTROL OF INDUCTION MOTOR (VARYING VOLTAGE) |
The set up has built in see through top cover
in MS powder coated cabinet. The control
circuitry is given upon the front panel and
sockets are given to observe the motor
voltage and current waveforms. Since it is a
line operated unit thus isolation is provided by
small transformer at the observation points.
This demonstration unit use the small
induction motor 220V.
| S.C.R. PARALLEL INVERTERTO DRIVE AC INDUCTION MOTOR |
| The kit is designed to study SCRparallel inverter driven small acinduction motor. The kit consistsinverter transformer, 2 SCRs, oneinductor, one commutation capacitor, one small ac induction motor, triggercircuitwith variable frequency |
In some applications speed control of acinduction motor is required. The speed of an acmotor can be controlled by varying either theamplitude or the frequency of its supplyvoltage, or both. The variable voltage, fixedfrequency technique has the advantage of itslower cost. When the close loop monitorsystem is used. |
