What are the main parts of induction motor?
The stator of the three-phase induction motor consists of three main parts :
- Stator frame,
- Stator core,
- Stator winding or field winding.
What are the basic parts of a motor?
The components of an electric motor may include a rotor, thin sheets of stacked metal called laminations, a stator, wire windings, magnets, a commutator, brushes, poles, electrical interconnects and a housing.
What are the two main parts of an induction motor?
Like any other electrical motor, induction motor have two main parts namely rotor and stator.
What is induction motor and how it 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.
How does an induction motor start?
When the supply is connected to the stator of a three-phase induction motor, a rotating magnetic field is produced, and the rotor starts rotating and the induction motor starts. … At the time of starting, the motor slip is unity, and the starting current is very large.
What is induction motor principle?
The motor which works on the principle of electromagnetic induction is known as the induction motor. The electromagnetic induction is the phenomenon in which the electromotive force induces across the electrical conductor when it is placed in a rotating magnetic field.
What are the types of motors?
Types of Electric Motors
- AC Brushless Motors. AC brushless motors are some of the most popular in motion control. …
- DC Brushed Motors. In a DC brushed motor, brush orientation on the stator determines current flow. …
- DC Brushless Motors. …
- Direct Drive. …
- Linear Motors. …
- Servo Motors. …
- Stepper Motors.
What are 3 types of motor controls?
There are mainly there are three types of motor control circuits:
- Direct On Line Starter (DOL starter)
- Star Delta Starter.
- Auto Transformer Starter.
What are the main parts of DC motor?
These components are: a stator, a rotor, a yoke, poles, armature windings, field windings, commutator, and brushes.
What is synchronous speed?
Synchronous speed is a significant parameter for the rotating magnetic field-type AC motor. It is determined by the frequency and the number of magnetic poles. Synchronous speed No = [rps, revolutions per second] f = Frequency [Hz]
What are the parts of an electric motor and their functions?
Different Parts of an Electric Motor and Their Function
- A power supply – mostly DC for a simple motor.
- Field Magnet – could be a permanent magnet or an electromagnet.
- An Armature or rotor.
Where is current actually applied in an AC induction motor?
During operation, a current is applied through the stator, which induces a magnetic field and leads to the rotation of the rotor. The rotational speed of the shaft and the applied torque is dependent on the operating frequency and the number of pole pairs in the motor’s windings.
What are the uses of induction motor?
The single-phase induction motors are used in low power applications. These motors are widely used in domestic and industrial applications.
Some of the applications are mentioned below:
- Small fans.
- High speed vacuum cleaners.
- Electric shavers.
- Drilling machines.
What is the principle of a motor?
The principle of an electric motor is based on the current carrying conductor which produces magnetic field around it. A current carrying conductor is placed perpendicular to the magnetic field so that it experiences a force.
What are the advantages of induction motor?
Induction Motor Advantages:
- Induction motors are simple and rugged in construction. …
- Induction motors are cheaper in cost due to the absence of brushes, commutators, and slip rings.
- They are maintenance free motors unlike dc motors and synchronous motors due to the absence of brushes, commutators and slip rings.
