Beside this, 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.

Also, what are the main parts of 3 phase induction motor? The stator of the three-phase induction motor consists of three main parts :

  • Stator frame,
  • Stator core,
  • Stator winding or field winding.

In this manner, what are the major parts of an induction motor?

Parts of an Induction Motor

  • A.C. MOTOR CONSTRUCTION: The A.C. Induction Motor has three main parts, rotor, stator and enclosure.
  • STATOR CORE: The stator is the stationary part of the motor's electromagnetic circuit and is made up of thin metal sheets, called laminations.
  • STATOR WINDINGS:
  • ROTOR CONSTRUCTION:
  • ENCLOSURE:
  • BEARINGS AND FAN:

How does an induction motor works?

An induction motor or asynchronous motor is an AC electric motor in which the electric current in the rotor needed to produce torque is obtained by electromagnetic induction from the magnetic field of the stator winding. An induction motor can therefore be made without electrical connections to the rotor.

What is motor made of?

What's Inside an Electric Motor? The coil is made of copper wire, because copper is such an excellent conductor. It is wound onto an armature. The coil becomes an electromagnet when a current flows through it.

How many moving parts are in a electric motor?

An electric motor may have as few as half a dozen moving parts, depending on how you count parts as moving or non moving. A very simple electric motor can have as few as three moving parts, the shaft and a bearing on each end.

What are the basic 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 is the function of a motor?


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 rotation of a shaft.

What are the main parts of an electric 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 is meant by induction motor?

Definition of induction motor. : an alternating-current motor in which torque is produced by the reaction between a varying magnetic field generated in the stator and the current induced in the coils of the rotor.

Which type of winding is induction motor?

There are two-types of rotor windings: Squirrel-cage windings, which produce a squirrel-cage induction motor (most common) Almost 90% of the three-phase AC Induction motors are of this type. A wound rotor or slip ring motor has a 3-phase winding, similar to the stator winding.

What is a single phase induction motor?

Single phase induction motor is an AC motor were electrical energy is converted to mechanical energy to perform some physical task. This induction motor requires only one power phase for their proper operation. They are commonly used in low power applications, in domestic and industrial use.

What is the slip?


Slip can be defined as the difference between the flux speed (Ns) and the rotor speed (N). Speed of the rotor of an induction motor is always less than its synchronous speed. It is usually expressed as a percentage of synchronous speed (Ns) and represented by the symbol 'S'.

What is 3phase induction motor?

The three-phase induction motor is an alternating current motor which is driven by the electromagnetic torque generated by the interaction between the rotating magnetic field formed by the stator winding and the magnetic field of the induced current in the rotor winding. It belongs to a kind of induction motor.

Why the induction motor is self starting?

The current carrying rotor being placed in a magnetic field experiences a torque and hence begins to rotate in the direction of rotating magnetic field. Thus we see that Induction Motor is self-starting. A 3-phase supply is given to the armature of Synchronous Motor, produces a rotating magnetic field.

How many slots are there in induction motor?

The first motor has 24 stator slots and is investigated with rotor slots 20, 29 and 32 and the second motor has 36 slots and is investigated with rotor slots 28 and 44. The above-mentioned rotor slots numbers have been selected based on manufacturer's database.

What is synchronous speed?

In a motor, synchronous speed is the speed at which the magnetic field rotates. Depending on motor design, the actual mechanical speed may be equivalent (synchronous motor) or slightly smaller (asynchronous motor). The synchronous speed is a function of: The electrical frequency used, typically 60 Hz or 50 Hz.

What is a stator made up of?


It consists of a steel frame enclosing a hollow cylindrical core (made up of laminations of silicon steel). The laminations are to reduce hysteresis and eddy current losses.

What are the applications of 3 phase induction motor?

Three-phase AC induction motors are widely used in industrial and commercial applications. These are of two types, squirrel cage and slip ring motors. Squirrel cage motors are widely used due to their rugged construction and simple design. Slip ring motors require external resistors to have high starting torque.

How is a 3 phase motor wound?

A three-phase, wound-rotor induction motor consists of a stator core with a three-phase winding, a wound rotor with slip rings, brushes and brush holders, and two end shields to house the bearings that support the rotor shaft. ills 1, 2, 3, and 4 show the basic parts of a three-phase, wound-rotor induction motor.
