In previous post, we learn how induction motors works and their parts also.Hope you dummies will understand the working principle too. Now going to learn something about the motor parts. Not too many but only one parts that is rotor (The rotating part of the motor). So what so special about rotors. Right now dummies let look some theory about rotors.
Unlike motor's stator has many windings,but in rotor has two type of rotor. One is Squirrel cage rotor and another is Wounded rotor. The both rotors has common and differences. SO let compare them and choose which rotor is the best.
The common in this both rotors are it create magnetic field and allign stator magnetic field to rotate.
1. Squirrel Cage Rotor
Squirrel cage rotor are commonly used in induction motor. The construction of this rotor are simple to understand. This rotor has conductor bar made of copper or aluminum. The conductor bar are short circuit by placing end rings. Steel lamination are place in the rotor with conductor bar. The reason why steel lamination are provide efficiency and prevent heating up.
2.Wound Rotor
Wound rotor has same construction like squirrel cage,but little different. This rotor has rotor winding and slip rings. It also laminated core to provide efficiency and prevent heating. This rotor also used in induction motor and this motor also know as synchronous motor. The rotor get supply by DC power source.
Which one is best ? Squirrel cage rotor or Wound rotor?
To determine which one is the best, Well you need to know the difference.These rotors play important role in to turn electrical energy into mechanical energy. The picture below shown is the difference between these rotor and dummies you will determine which one is better
IN MY OPINION, SQUIRREL CAGE ROTOR IS THE BETTER,BECAUSE HAS HIGH EFFICIENCY AND LESS MAINTENANCE. SO WHAT'S YOUR THOUGHT LEAVE A COMMENT AND STAY ELECTRIFY
