First of all every induction motor has a fixed Tem, i.e. Maximum Torque and to deliver 2000 watt of power a motor has to produce corresponding torque (Power=Torque* rpm). And N=120*f/P so rpm can be at max 3000 with 2 pole machine. So to develop 2000 watt of power it is the requirement of torque rather than simply the speed.

Salient pole alternator is more stable, why?
