Parameter estimation of squirrel-cage motors with parasitic torques in the torque–slip curve

This paper studies parasitic torques in steady-state torque–slip curves of squirrel-cage induction motors. The curves of nine motors (small, medium and large size units), three of which were measured in the range s = 2 to 0, are analysed. The torque–slip curves of eight of these nine motors differ s...
