Abstract :
In this article we build the differential equations of the damper winding´s temperature rise, find the progression solution of them and derive the starting limit time characteristic in the winding, put forward a new effective protection according to the LTC. Meanwhile, we consider the influence on the temperature rise and dissipating heat from the variations of the damper winding´s current and the speed when the motor starts
