Beschreibung
Zusammenfassung: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.
