electric motor
The electric motor is an electromagnetic device that converts electrical
energy into mechanical
energy. Mechanical
energy is used for, for example, rotating impeller
pump, fan or blower, compressor moving, lifting materials, etc.. Electric motor
used also in the house (mixer, electric drill, fan wind) and in industry. Electric motor.
sometimes called the "work horse" because it is estimated that industrial motors
use about 70% of the total electrical load in the industry.

Mechanism of action for all types of motorcycles are generally the same:
Electric current in a magnetic field will exert a force, if the current-carrying wire is bent into a circle / loop, then, both sides of the loop is at right angles to the magnetic field, will gain force in the opposite direction, the style pair produces power play / torque to rotate coils, motors have several loops on his dynamo to provide a more uniform torque and the magnetic field generated by the electromagnetic structure of the so-called field coils.
In understanding a motor, it is important to understand what is meant by burden
motor. Expense refers to the output power play / torque according to the speed
required. Expenses can generally be categorized into three groups (BEE India, 2004):
Constant torque load is a load where the demand for its
energy output varies
with the speed of its operation but the torque does not vary. Sample load
constant torque is conveyors, rotary kilns, and the constant displacement pump, with
variable torque load is a load with a torque that varies with
operating speed. Examples with
variable torque loads are centrifugal pumps and
fan (torque varies as the square of velocity).
