Electrical transformer is a static electrical machine which transforms electrical power from one circuit to another circuit, without changing the frequency. Transformer can increase or decrease the voltage with corresponding decrease or increase in current. Working principle, construction and types of transformer -

The electric motor function in an easy way. First, the electric motor should have a power input to make the coil heat, its called electromotive force.

An electric motor is a device converting electrical energy into mechanical energy (usually a torque). ... The output torque of an electrical motor depends on the intensity of the rotor and stator magnetic fields and on their phase relation: B sta B rot

From tiny hysteresis motors that drive electric clocks to huge synchronous motors that develop more than 50,000 hp, the alternating current (AC) motor has become an indispensable part of everyday life. These omnipresent devices come in many varieties, but generally fall into two categories: synchronous and induction machines.

Electric motor - WikipediaAn electric motor is an electrical machine that converts electrical energy into mechanical energy. The reverse of this is the conversion of mechanical energy into electrical energy and is done by an electric generator, which has much in common with a motor.

In electrical engineering, an armature is the power-producing component of an electric machine. The armature can be on either the rotor (rotating part) or the stator (stationary part) of the electric machine.

Every electric motor has two essential parts: one stationary, and one that rotates. The stationary part is the stator. Though configurations vary, the stator is most often a permanent magnet or row of magnets lining the edge of the motor casing, which is usually a round plastic drum.

Ferrite magnet type motors, which use permanent magnets, are used for the wiper motors. The wiper motor consists of the motor itself and the gears, which reduce the speed output by the motor. The ferrite type wiper motor uses three brushes: a low-speed brush, a high-speed brush, and common brush (for ground).

The stator and the rotor are each made up of: An electric circuit, usually made of insulated copper or aluminum, to carry current; A magnetic circuit, usually made from laminated steel, to carry magnetic flux; The stator. The stator is the outer stationary part of the motor, which consists of:

The basic function of all and any electrical machine is to make use of the magnetic field produced in the air-gap between stator and rotor for the transfer of and conversion of electrical to mechanical energy commonly know as electro-mechanical energy conversion.

By definition, an electric motor is a device that converts electrical energy into mechanical energy. An electrical signal is applied to the input of the motor, and the output of the motor produces a defined amount of torque related to the characteristics of the motor.

The stator is the stationary part of a rotary system, found in electric generators, electric motors, sirens, mud motors or biological rotors. Energy flows through a stator to or from the rotating component of the system.

An electric motor is an electrical machine that converts electrical energy into mechanical energy. Most electric motors operate through the interaction between the motor's magnetic field and winding currents to generate force in the form of rotation.

The main parts of an electric motor include the stator and rotor, a series of gears or belts, and bearings to reduce friction. DC motors also need a commutator to reverse current direction and keep the motor …
