초록
The torque characteristic of an induction motor is affected greatly by the slot shape at which the conductors of the rotor are located. In this paper, the three analysis model; general type, deep slot type, double squirrel-cage type, of which the slot shapes are different, were analyzed by FEM at no load, at rated load, and at standstill respectively. The flux distribution and air-gap flux density were also obtained. From the above result, it was confirmed that the analysis models of deep slot and double squirrel-cage had more desirable characteristics than those of general squirrel-cage.
