In designing rotors for induction motors, the shape and dimensions of the slots have a demonstrable effect on the performance characteristics of the motor. The slot (bar) shape can be seen in the lamination examples in the photo. Another design factor common to most squirrel cage... Induction Motor Interview Questions & Answers - Engineering… In the induction motor design, the rotor slots are purposely made with a slight skew arrangement. It will not be parallel to the shaft. This is for the purpose of reducing magnetic locking or reducing magnetic attraction between stator and rotor teeth. Induction Motor Rotor - Electrical Edition Induction Motor Rotor: Induction motors are available with two types of rotors basically.The rotor consists of a cylindrical laminated core with parallel slots for carrying the rotor conductors which, it should be noted clearly, are not wires but consist of heavy bars of copper, aluminium or alloys.

The rotor of the an induction motor is slotted carefully according to which the rotor winding is done … the number of rotor slots are equal to the number of stator slots…according to the stator slots also the three phase 120 degre placed star connected winding is done …

The induction motor design is strongly connected to the power electronics design, since different motor configurations strongly affect its electromagnetic characteristics. This is the reason for extensive research worldwide [3, 4]. This paper constitutes a study of the impact of the rotor slot selection on... Selection of Copper vs. Aluminum Rotors for Induction … induction motor works. Additionally, an understanding of how different performance characteristics can be achieved by altering the rotor design isHowever, if the rotor bar resistance is doubled, the locked rotor torque will not be doubled since the rotor slot impedance, which is the sum of rotor slot... Induction Motor Rotor | Electrical4U Induction motor rotor is of two types: Squirrel Cage Rotor Wound Type Rotor or Slip Ring Type Rotor Squirrel Cage Rotor In this type…Rotor as the name suggests it is a rotating part of an electrical machine, in which current is induced by transformer action from rotating magnetic field.
