In most generators, the field magnet is rotating, and is part of the rotor, while the armature is stationary, and is part of the stator. Both motors and generators can be built either with a stationary armature and a rotating field or a rotating armature and a stationary field.
What is the rotating part of a motor called?
With this simple understanding, we can divide any motor into two physical parts; one part which rotates—called the rotor—and one part which doesn’t— called the stator. Figure 1 shows a simple diagram of an electrical machine showing the rotor and stator.
What are the parts of an electric motor called?
No matter the type of motor, there are three basic parts: a stator, a commutator, and a rotor. Together they use electromagnetism to cause the motor to spin. As long as the motor receives steady current, the motor works.
Is the rotating part of a motor?
The rotor is located inside the stator and is mounted on the AC motor’s shaft. The term “rotor” is derived from the word rotating. The rotor then is the rotating part of the AC motor. The objective of these motor components is to make the rotor rotate which in turn will rotate the motor shaft.
How does a motor create rotation?
A coil of wire carrying a current in a magnetic field experiences a force that tends to make it rotate. This effect can be used to make an electric motor.
What are the three basic part of an electric motor?
Electric motor designs can vary quite a lot, though in general they have three main parts: a rotor, a stator and a commutator. These three parts use the attractive and repulsive forces of electromagnetism, causing the motor to spin continually as long as it receives a steady flow of electric current.
What is the relationship between an electric motor and magnetism?
An electric motor converts electrical energy into physical movement. Electric motors generate magnetic fields with electric current through a coil. The magnetic field then causes a force with a magnet that causes movement or spinning that runs the motor.
