Industrial Electric Motor

Industrial Electric Motor
As a driving force in the industry many people use electric motors

This section describes the main features of the electric motor.
1.1 Where is the motor used
Electric motor is an electromagnetic device that converts electrical energy
into mechanical energy. This mechanical energy is used to, for example, rotating impeller
pump, fan or blower, a compressor driving, lifting materials, etc.. Electric motor
used also in the home (mixer, electric drill, a fan of wind) and in industry. Electric motor
sometimes called the "work horse" because it is estimated that industrial motors
using about 70% of total electrical load in the industry.
2.1 How a motor works
The mechanism of action for all types of generally the same motor (Figure 1):
- An 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, ie at right angles to the magnetic field, will get the force on
opposite direction.
- The pair produces a force play force / torque to rotate the coil.
- Motor-bike has a few loops on dinamonya to provide torque
more uniform and the composition of the magnetic field generated by electromagnetic
called the field coil.
In understanding a motor, it is important to understand what is meant by burden
motors. Refers to the output load power play / torque according to the speed
required. Expenses can generally be categorized into three groups (BEE India, 2004):
- Expenses are constant torque loads where requests vary the energy output
with a torque-speed operation but it does not vary. Example of an expense
constant torque is Conveyors, rotary kilns, and the constant displacement pump.
- Expenses with variable load torque is a torque which varies with
operating speed. Examples with variable torque loads are centrifugal pumps and
fan (torque varies as the square speed).

- Cost of energy is a constant torque load with the changing demand
and inversely proportional to velocity. Examples for the constant power load
is the machine tools.
Electric motor components varies for different types of motors, in chapter 2 is described for
each motor.
