Wound Type
Given Below is the construction and advantages of the Wound Type Rotors
Construction of Wound Type
- It consists of a laminated cylindrical core and carries a 3 phase winding (similar to stator).
- Rotor windings are uniformly distributed in the slots and are generally star- connected.
- The open ends of rotor windings are connected to three insulated slip rings on the rotor shaft with one brush on each slip ring.
- Initially, the external resistances are included in the rotor circuit to give a large starting torque.
Advantages of Wound Type
- External Resistances can be added as rotor bars are permanently short-circuited.
- Provides high starting torque
- Power factor can be easily improved.
- Efficient speed control
What is Rotor?
Rotors are a fundamental part of electrical machines and play an important role in their operation. Rotor is the rotating part of an induction motor. It is connected to the mechanical load through the shaft. There are various designs of rotors available on the basis of application and type of machine, such as squirrel cage or wound type.
In this article we will go through the definition of the Rotor with its construction in detail with its diagram, we will also go through the classification of Rotors and difference between stator and rotor, At last we will conclude our article with some of its applications and FAQs.
