Necessity:
Normally the Slip Ring Induction motor is used Variety of applications such as Rolling of high voltage Electrical cables, Telephone cables etc., where we have a lot of torque and speed control is required. The speed control in Slip Ring Induction Motor is done by varying the voltage drop at the outputs of the motor, using a rheostat. This Project consists of necessary hardware for driving a Slip Ring Induction Motor. Normally the slip voltage from the motor is dropped using a high wattage resistor or a heater which has no use. In this project we have included the slip voltage recovery system, Where the slip voltage is used to charge a Battery, so that the battery can be used at later time.
Operation:
The voltage outputs from the induction motor is first rectified and is controlled using IGBT section. The speed can be varied by applying the PWM Pulses to the IGBT Section from the PIC Microcontroller. The voltage drop at the output side is given as a input to the Battery for charging.
