ELECTRIC MOTOR

An electric motor is an electrical machine that converts electrical energy

into mechanical energy. In normal motoring mode, most electric motors operate

through the interaction between an electric motor's magnetic field and winding

currents to generate force within the motor . Electric motor can be found in

applications as diverse as industrial fans, blowers and pumps, machine tools,

household appliances, and compressor.

Electric motors may be classified by electric power source type, internal

construction, application, type of motion output, and so on. Electric motors can be

powered by direct current (DC sources, such as from batteries and many more . DC

motors consists of a dc motors separately e!cited and dc motors self e!cited . Direct

Current Electric "otors can be a DC #enerator or DC Electric "otors . DC

#enerators is an electrical machine that converts mechanical energy into electrical

energy . A DC motors can be used as a generator or conversely . Electric motors can

be powered by alternating current (AC sources, such as from the power grid,

inverters or generators . AC motors consists of a synchronous AC motors and

asynchronous AC motors . $hree%phase s&uirrel%cage induction motors are widely

used in industrial drives because they are rugged, reliable and economical. ingle% phase induction motors are used e!tensively for smaller loads, such as household

appliances lie fans and pumps .

AC motors has two direction of rotation that is AC motors clocwise and

AC motors counter cloc wise . Counter cloc wise AC motors can be produced by

shifting one phase . o the electric motor is used to convert electrical energy into

mechanical energy , this change was made by converting electricity into magnetism

nown as electro magnets , as we now that the poles of a magnet that will repel

namesae and poles are not namesae , attraction. $hen we can get the movement if

we put a magnet on a rotatable shaft , and the other magnet in a fi!ed position .
