An anti -theft system for electric motor includes controller, feedback circuit and alarm circuit. The feedback circuit continuously monitor the electric motor load, if the motor load is disconnected controller gives alarm with the help of buzzer This paper reports the design and development of an innovative anti -theft alarm system for electric motor pumps. The pumps are frequently stolen which as serious impact on agricultural production in accordance with the advantage of current transformer,

The Electric Motor costs are very high, when motors are on,it's very simple to detect the stealing of cables and motors when motors are off,it's very difficult to detect the stealing of the motors. The unit is part of motor driving circuit, cannot be identified easily as an anti-theft electric motor by the burglar
