www.ijiset.com Effects of Rotor Slot Area on Squirrel Cage ... Induction motor, Performance analysis, Rotor slot area, Slot height, Slot width. 1. Introduction . The design of the induction motor is a highly complex process. Many different variables such as output power, losses, efficiency, nominal torque, current etc. must be considered to obtain the desired motor parameter values. Induction motor - Wikipedia 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. An induction motor's rotor can be either wound type or squirrel-cage type. Optimization of Motor Rotor: Slot Shape, Frame Size, Rotor ...

Design of Rotor - Induction Motors number of conductors / rotor slots and I'r – equivalent rotor current in terms of stator current. and is given by I'r = 0.85 Is where is stator current per phase.Design of wound Rotor: These are the types of induction motors where in rotor also carries distributed star connected 3 phase winding. Design of Induction Motors.pdf - Free Download PDF • Rotor is the rotating part of the induction motor. The rotor also consists of a set of slotted silicon steel laminations pressed together to form of a cylindrical magnetic circuit and the electrical circuit.In order to get the above design details the designer needs the customer specifications. Why are the slots on the rotor of an induction motor… In Squirrel cage rotor, slots in lamination or rotor core is not made parallel to the rotor shaft. A slight angle is maintained due to some advantages.This is called the rotor Skew.
