dc.description.abstract | 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 s = 0, are analyzed. The torque-slip curves of eight of these nine motors differ significantly from the smooth curves predicted by the classical single- and double-cage models: a torque dip at large slips in the motoring regime and a noticeable torque increase in the braking regime occur. As parasitic torques have been traditionally associated with space harmonics, two single-cage chain models (which consider the space harmonics) are tested to fit the measured torque and current of the three measured motors: one neglects the skin effect, leading to the wrong torque prediction while the other (the classical chain model in the literature) considers the skin effect, leading to an accurate torque prediction. | ca_CA |
