What are the parts of AC motor?
The main components of an AC motor are the stator, stationary outer drum, and the rotor, the rotating inner portion attached to the motor shaft. The stator and the rotor produce rotating magnetic fields. The winding of the stator that creates the rotating field is created by alternating current.
What are the two parts of a motor?
An electric motor consists of two major parts, the rotor and stator (see Figure 5).
What is an electric motor Class 10?
Electric motor is a device that converts electrical energy to mechanical energy. Parts of a Electric Motor. Insulated Copper wire: A rectangular coil of wire ABCD. Magnet Poles: A magnet as placed above ie North Pole and South Pole.
What is a rotor in electric motor?
Rotors are the moving part in an Alternator that have permanent magnets that move around the Stator’s iron plates to generate an Alternating Current (AC). Rotors require existing motion to function, so only once the engine or turbine is already running will a Rotor work with a Stator to provide a charge.
What are parts of DC motor?
DC motors include two key components: a stator and an armature. The stator is the stationary part of a motor, while the armature rotates. In a DC motor, the stator provides a rotating magnetic field that drives the armature to rotate.
What metals are in electric motors?
- Iron is the cheapest of the three, so many designers turn there first.
- Cobalt is rarely used on its own, but is sometimes added to iron. …
- Nickel is expensive but valuable to motor applications.
What is an armature enumerate its parts?
Armature Components. An armature can be designed with the number of components namely the core, the winding, the commutator, & the shaft.
What is an electric motor in physics?
An electric motor is an electrical machine that converts electrical energy into mechanical energy. Most electric motors operate through the interaction between the motor’s magnetic field and electric current in a wire winding to generate force in the form of torque applied on the motor’s shaft.
What is construction of electric motor?
The electric motor construction can be done using the rotor, bearings, stator, air gap, windings, commutator, etc. electric-motor-construction. Rotor. 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.

How many types of electric motors are there?
Two Types of Electric Motors
There are at least a dozen different types of electric motors, but there are two main classifications: alternating current (AC) or direct current (DC).
What are the 2 main parts of a 3 phase AC motor?
A three-phase motor has two main parts: the rotor, which turns, and the stator that turns it.
What is a split-phase motor?
A split-phase induction motor is a type of single-phase induction motor in which the stator is provided with a starting or auxiliary winding (S) and a main or running winding (M). … The starting winding operates only during the brief period when the motor starts up.
What is torque of a motor?
Torque is a rotating force produced by a motor’s crankshaft. The more torque the motor produces, the greater is its ability to perform work. Since torque is a vector acting in a direction it is commonly quantified by the units Nm or pound-feet.
What are different parts of stator?
The stator core, stator winding and the outer frame are the three parts of the stator whereas the rotor core and field winding are the parts of the rotor. The three-phase supply is given to the winding of the stator.
What are rotors and stators?
The term, “stator” is derived from the word stationary. The stator then is the stationary part of the AC motor. The rotor is the rotating electrical component. … The term “rotor” is derived from the word rotating. The rotor then is the rotating part of the AC motor.
What are the 4 types of DC motor?
- Permanent Magnet DC Motors. The permanent magnet motor uses a permanent magnet to create field flux. …
- Series DC Motors. In a series DC motor, the field is wound with a few turns of a large wire carrying the full armature current. …
- Shunt DC Motors. …
- Compound DC Motors.
What are the 3 types of DC motors?
There are 3 main types of DC motor that are available:- Series, Shunt and Compound. These terms relate to the type of connection of the field windings with respect to the armature circuit.
What are motor windings made of?
The most commonly used material for winding is copper. Aluminum can also be used but it should be thicker to hold a similar load securely. The copper winding allows for a tiny sized motor. These motor windings are very important components within an electrical machine.
What kind of copper is in electric motors?
The copper content varies among different types of motors, while small motors have a higher percentage of copper per weight than heavy motors. On average, fractional electric motors are 9-10 percent copper by weight. AC motors average 7-9 percent copper; DC motors have 15-18 percent copper content. 4.
Why is copper used in motors?
Copper. … Copper is a great choice for motor windings because of its high conductivity and relatively low cost, but it is also a highly dense and heavy material; this is even more of a problem for motors used in electric vehicles or aircraft, which need to be lightweight.
What is yoke motor?
The magnetic frame or the yoke of DC motor made up of cast iron or steel and forms an integral part of the stator or the static part of the motor. Its main function is to form a protective covering over the sophisticated inner parts of the motor and provide support to the armature.
What is back EMF in motor?
Back EMF is the system in the coil of an electric motor that opposes the current flowing through the coil, when the armature rotates. When the speed varies, the winding characteristics may fluctuate, resulting in variation of back EMF.
