There are mainly two types of induction motor. This classification is based on what power supply induction motors are fed with. Single-phase induction motors and three-phase induction motors are the two main types of induction motors.
What are the different types of 3 phase induction motors?
There are three types of 3- phase induction motors namely plain or squirrel cage induction motor, slip-ring or wound rotor induction motor and double cage rotor induction motor.
What is the 3 phase induction motor?
A 3 phase induction motor derives its name from the fact that the rotor current is induced by the magnetic field, instead of electrical connections. The operating principle of a 3 phase induction motor is based on the production of r.m.f.
What are 3 phase induction motors used for?
Applications for 3 Phase AC Induction Motors
By converting electrical energy into mechanical energy, 3 phase AC induction motors can drive a huge range of components—from pumps and fans to compressors and conveyors—in industrial or higher-power applications.
What are the two main components of an induction motor?
Like any other electrical motor, induction motor have two main parts namely rotor and stator. Stator As the name indicates stator is a stationary part of induction motor. A three phase supply is given to the stator of induction motor.
What are the disadvantages of induction motor?
Disadvantages of induction motor:
- The power factor of the motor is very low during light load conditions.
- During light load conditions, it operates at a very low power factor.
- It has low efficiency.
- Single-phase induction motor is not self-starting.
Is a 3-phase induction motor self starting?
Three-phase induction motor is self-starting, because winding displacement is 120 degrees for each phase and supply also has 120 phase shift for 3-phase. It results in a unidirectional rotating magnetic field is developed in air gap which causes 3-phase induction motor to self-start.
What is stripping in induction motor?
Coldsweep’s induction stripping equipment removes your toughest coatings from steel structures with no noise or secondary waste—getting right down to the steel. … Coldsweep’s jaw-dropping induction dis-bonding process removes most coating types, including: Coal Tar Epoxy.
What are the main parts of induction motor?
Parts of Induction Motors
- Stator. The stator is the stationary portion of the motor and delivers a rotating magnetic field to interact with the rotor. …
- Rotor. The rotor is the central component of the motor, and is fixed to the shaft. …
- Shaft. The motor shaft is fixed within the rotor, and rotates with it. …
- Bearings. …
- Casing.
What is the principle of induction motor?
Working Principle of Induction Motor
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.
