An electric motor is a device used to convert electricity into mechanical energy—opposite to an electric generator. They operate using principles of electromagnetism, which shows that a force is applied when an electric current is present in a magnetic field.
How do motors work?
How do motors work? Electric motors work by converting electrical energy to mechanical energy in order to create motion. Force is generated within the motor through the interaction between a magnetic field and winding alternating (AC) or direct (DC) current. … Electric Motors have an array of applications.
What is the function of each part of the motor?
The main parts of an electric motor include the stator and rotor, a series of gears or belts, and bearings to reduce friction. DC motors also need a commutator to reverse current direction and keep the motor spinning.
What are 3 main parts of a 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 are the two main components of an electric motor?
The two main components of this kind of motor are the stator (stationary element) and the rotor (rotating element). The stator is a fixed part of the stationary motor.
What is electric motor explain with diagram?
1) When electric is passed into the rectangular coil, magnetic field is produced around the coil. 2)The magnetic field of horse shoe type interacts with the magnetic field on the coil and causes the coil to rotate continuously.
How do I know if a motor is AC or DC?
Look for the stator core construction and rotor. If there is no commutator, then it is a AC motor. If there is a commutator and brushes, it may be either a DC motor or an AC commutator motor (Universal motor).
What is motor and its working principle?
Electric motor: A motor is a device which converts electrical energy into mechanical energy. Principle of motor : A motor works on the principle that when a rectangular coil is placed in a magnetic field and current is passed through it. A force acts on the coil which rotates it continuously.
What are the 4 parts of an electric motor?
The Parts of an Electric Motor
- Stator. The stationary part of an electric motor is the stator. …
- Rotor. The main moving part of an electric motor is the rotor which turns a shaft to deliver force to whichever unit is being powered. …
- Air Gap. …
- Windings. …
What do we call a part that moves when the motor is working?
The rotor is the moving part of your electric motor. It turns the shaft that delivers the mechanical power mentioned above. In a typical configuration, the rotor has conductors laid into it that carry currents which then interact with the magnetic field of the stator to generate the forces that turn the shaft.
