AC MOTOR REWINDING

Three-phase asynchronous squirrel-cage motors (induction motors) are often used in industrial applications because of their low cost, relatively simple manufacturing and robust construction.
In all the years since the first induction motor was produced, induction motors
have been developed and modified for several reasons

The efficiency of induction motor depends on different factors:

• producer’s technology (purity of squirrel cage material
• quality of bearings,
• quality of lamination materials,
• construction of housing (additional losses)
• Type of winding which is inserted into the stator slots.

Moreover, the type of winding can have significant influence on induction motor efficiency.
