Design of stator & rotor for Wound Induction Motor | PPTX
The document provides details on the design of stator and rotor slots for a 3-phase wound-rotor induction motor. It discusses the construction of the motor including the stator core and winding, wound rotor with slip rings, and end shields. For stator design, it describes slot types, selection of number of slots, conductor cross-section, slot area and size, length of mean turn and resistance calculation. For rotor design, it discusses air gap length, number of rotor slots selection to avoid crawling and cogging, end ring current, design of wound rotor including number of turns and rotor current calculation. It provides an example design problem for a 30kW squirrel cage induction motor and asks to design a suitable rotor - Download as a PPTX, PDF or view online for free
