The electronic circuit designed by Kamble attempts to provide a total protection to the motor as far as possible within a limited budget. It is specifically targeted at the motors meant for powering water pumps for agricultural applications. The circuit switches off the motor when any of the functional parameters gives rise to the possibility of burn out of the field coils. Some of the components used in the circuit are single-phase preventor, current sensor, overload timer, temperature sensor, voltage level sensor, day/night system, etc. Miniature pilot lamps light up to indicate the exact reason for which the supply to a motor is tripped. By eliminating the particular fault, or by waiting till the fault automatically gets eliminated before restarting the motor, it is possible to eliminate motor burn out.
