What is motor?and explain working of motor

Question

Accepted Answer

A motor is a device that converts electrical energy into mechanical energy to produce motion.

Motors can be classified into different types such as DC motors, AC motors, and stepper motors.
The basic working principle of a motor involves the interaction of magnetic fields to generate force and motion.
In a DC motor, current flows through a coil within a magnetic field, creating a force that rotates the motor shaft.
In an AC motor, the direction of the current changes periodically, causing the magnetic field to also change direction and produce rotation.
Stepper motors move in discrete steps based on the input pulses received.
Motors are widely used in various applications such as industrial machinery, household appliances, and automotive systems.

Accepted Answer

Electric motors can be powered by direct current (DC) sources, such as from batteries or rectifiers, or by alternating current (AC) sources, such as a power grid, inverters or electrical generators.

Electric motors may be classified by considerations such as power source type, construction, application and type of motion output. They can be brushed or brushless, single-phase, two-phase, or three-phase, axial or radial flux, and may be air-cooled or liquid-cooled.

Standardized motors provide power for industrial use. The largest are used for ship propulsion, pipeline compression and pumped-storage applications, with output exceeding 100 megawatts.

Applications include industrial fans, blowers and pumps, machine tools, household appliances, power tools, vehicles, and disk drives. Small motors may be found in electric watches. In certain applications, such as in regenerative braking with traction motors, electric motors can be used in reverse as generators to recover energy that might otherwise be lost as heat and friction.

Electric motors produce linear or rotary force (torque) intended to propel some external mechanism. This makes them a type of actuator. They are generally designed for continuous rotation, or for linear movement over a significant distance compared to its size. Solenoids also convert electrical power to mechanical motion, but over only a limited distance.

Accepted Answer

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 electric current in a wire winding to generate force in the form of torque applied on the motor's shaft.
