The AC motor commonly consists of two basic parts, an outside stator having coils supplied with alternating current to produce a rotating magnetic field, and an inside rotor attached to the output shaft producing a second rotating magnetic field.
What is the construction of AC motor?
Construction of AC Motor
It consists of a Frame or Yoke, stator, rotor, bearings, fan, shaft, and slip rings. The parts of an AC machine is explained below. The frame is used as an outer protecting cover that is used to protect against environmental conditions.
How are electric motors constructed?
The electric motor construction can be done using the rotor, bearings, stator, air gap, windings, commutator, etc. The rotor in an electric motor is the moving part, and the main function of this is to rotate the shaft for generating the mechanical power.
What are the components of an AC motor?
The AC motor consists of two main parts: the rotor and the stator. The stator is the outer shell and remains stationary. It has windings that transform the incoming electricity into a magnetic field.
What are the three basic parts of an AC motor?
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.
What is AC motor with diagram?
An AC motor is an electric motor driven by an alternating current (AC). The AC motor commonly consists of two basic parts, an outside stator having coils supplied with alternating current to produce a rotating magnetic field, and an inside rotor attached to the output shaft producing a second rotating magnetic field.
Where are AC motors used?
General uses for AC motors include pumps, water heaters, lawn and garden equipment, ovens, and off-road motorized equipment. In fact, many of the appliances, equipment and tools you use on a daily basis are powered by an AC motor.
What are the 6 parts of an electric motor?
These six components include:
- 1) The Rotor. The rotor is the moving part of your electric motor. …
- 3) The Bearings. The rotor in your electric motor is supported by bearings, which allow it to turn on its axis. …
- 4) The Windings. …
- 5) The Air Gap. …
- 6) The Commutator. …
- What Do All of These Components Have in Common?
What is electric motor give two examples where electric motor is used?
The largest electric motors are used for ship propulsion, pipeline compression and pumped-storage applications with ratings reaching 100 megawatts. Electric motors are found in industrial fans, blowers and pumps, machine tools, household appliances, power tools and disk drives.
What is the role of commutator in electric motor?
The commutator assures that the current from the generator always flows in one direction. … On DC and most AC motors the purpose of the commutator is to insure that the current flowing through the rotor windings is always in the same direction, and the proper coil on the rotor is energized in respect to the field coils.
What is the most common type of AC motor?
Induction motor rotors are the most common type of AC motor and are used for various types of pumps, compressors, and other machines.
What are the 2 main parts of a 3 phase AC motor?
The Parts of the Motor
A three-phase motor has two main parts: the rotor, which turns, and the stator that turns it.
What determines the rpm of an AC motor?
In most cases, you can look inside the motor and count the number of poles in the winding; they are distinct bundles of wire evenly spaced around the stator core. The number of poles, combined with the ac line frequency (Hertz, Hz), are all that determine the no-load revolutions per minute (rpm) of the motor.
Do AC motors have brushes?
AC induction motors have no brushes and have a much longer life expectancy. DC motor speed is controlled by varying the armature current, while AC motor speed control is achieved by varying the frequency of the alternating current, often with a variable frequency drive(VFD).
What is the cost of AC motor?
₹ 1000 / PieceBy: JK Refrigeration Co.
Are AC motors reversible?
In order to reverse the direction of an AC motor, the magnetic fields must be altered to provoke movement in the opposite direction. Since each wire consists of a positive and negative current within the magnetic fields, the flip-flopping of main and starter wires causes the motor to run in reverse rotation.
