The base idea of this paper is to control the
electromagnetic engine to enhance a smooth rotation by
measuring distance of the piston using an IR sensor. This
electromagnetic engine consists of an electromagnet, permanent
magnet, Infrared Sensor, powerful microcontroller and power
supply. The permanent magnet acts as a piston in this
electromagnetic engine, it has magnetic field energy for a proper
function. The position of permanent magnet has to be noted for
electromagnets energisation in order to reduce power
consumption by electromagnet. The infrared sensor mounted
with electromagnet set and pointed towards permanent magnet,
whenever the permanent magnet moves towards electromagnet,
sensor reads the change in magnetic piston position. The
electromagnet is energized on the reach of permanent magnet
near electromagnet. Control of electromagnets power supply is
depends on the signal provided by IR sensor, this sensor is
mainly makes timing control of power drive circuit through the
microcontroller. This makes engine to run continuously and
reducing its power consumption by providing a pulse to
