Abstract

Transient Analysis of Electrical machines is the cynosure of attention and the subject of utmost interest of most\nmachine designers in their quest to improve machine reliability and achieve the perfect design. Stator being the static part of\nan induction machine is the seat of higher temperatures, Hence is more liable to thermal failure than the rotor. Thus the study\nof thermal profile of the stator becomes more critical to identify the causes of failure in an induction machine. This paper\npresents a two dimensional transient heat flow in the stator using arch shaped elements in the􀢘 − 􀣂 ɵ plane of the cylindrical\nco-ordinate system of an 11 KW TEFC Squirrel Cage induction motor under the condition of DC dynamic braking for\ndifferent values of stator currents injected in the stator of the aforesaid motor.
