- Stall torque
Stall torque is the
torque which is produced when an engine or motor stalls. In the case of apetrol engine ordiesel engine , the stall torque is zero because, when the engine stalls, it ceases to function. For this reason, a petrol or diesel engine normally drives through a transmission system which provides torque multiplication. This system may be a clutch and gearbox, electric transmission or hydraulic transmission [http://www.converter.cc/tech_talk/tech_main.htm] .Steam engine s and DCelectric motor s [ [http://www.gizmology.net/motors.htm Notes on Motors ] ] continue to provide torque even when stalled so a transmission system is not usually necessary. However, electric motors must not be left in a stalled condition because this would lead to overheating and possible damage.References
