The conversion of electromagnetic energy into the work performed by the industrial electric motors. The motors produce a linear or rotational force. What are the components of industrial electric motors? Let’s find in this article.
Components of industrial electric motors
Industrial electric motors can be powered by direct current (DC) sources such as batteries, but they are often powered by alternating current (AC) sources such as a generator or power grid. Here are the main components of Industrial electric motors:
Armature
The moving part of the motor is the armor (or rotor), which rotates the shaft to convert the energy into mechanical energy.
Typically, the armature has a conductor that carries currents that interact with the stator’s magnetosphere to create a force that rotates the shaft.
Most of the time, the armature is in the middle of the engine and rotates when the poles are attracted and then resisted by the stator poles.
Stator
The torque or power of the motor is determined by the magnetic cable length as well as the voltage at the stator.
As a central part of the electrical magnetic circuit, the core of the stator contains a thin metal sheet to reduce energy consumption. The stator may have a permanent magnet or winding.
Air Gap
An important element is the air gap between the rotor and stator which increases the magnetic flux.
Air gap distance is crucial in determining performance. Generally, the air gap should be as short as possible.
Winding or “Coil”
Windings are wires that are wound around a core, which is usually a soft iron magnet used to create or receive electromagnetic energy.
The winding wire has to be insulated and usually copper because it conducts electricity with a thin wire. Aluminum can be used but has to be denser.
Commutator
It is the switching mechanism that creates the reverse of the electric current and applies the machine to the pole as an alternative to the rotor to stop a motor without crashing the power current.
Drivers are usually made of slip ring segments that are insulated from each other and from the motor shaft.
A brush or any other process is employed to shift the current.
The industry increases the importance of electric motors
How important is an industrial electric motor? It’s very much important. Almost all modern industries employ one of several types of industrial electric motors.
In fact, the demand for industrial electric motors is expected to grow by 5.4 percent by 2018. It is growing day by day.
