Electrical Machines Project

Speed of two slip ring induction motors for different types of cascading operation, where the shaft of the motors are coupled with each other. Specifications of both the machines should be provided by the users.

Abstract

This web application is used to calculate the speed of two slip ring induction motors for two different types of cascading operation, where the shaft of the motors are coupled with each other.

It takes six inputs from the user:

• f1 = Frequency(Hz) of supply given to machine 1
• f1 = Frequency(Hz) of supply given to machine 1
• s1 = Slip of operation in machine 1
• s2 = Slip of operation in machine 2
• p1 = Number poles in machine 1
• p2 = Number poles in machine 2

Machine 1 - MIM (Main Induction Motor)
Machine 2 - AIM (Auxiliary Induction Motor)

We get speed (in radians) as output.

Case A : Torque of both machines are in same direction.

Speed = (120*f1)/(p1+p2)

Case B : Torque of both machines are in different direction.

Speed = (120*f1)/(p1-p2)
