“…Therefore, the saturation of flux density and the electrical conductivity of the materials have direct relation with the torque of motor. Sharma et al [11] aimed at maximizing the electromagnetic torque through depositing layers of Cu plus Fe-Co on the rotor surface. Other investigations indicated that, a better output torque and also a higher efficiency were considered as two significant advantages of a slotted solid rotor induction motor compared with a smooth one [12][13][14].…”

A B S T R A C TThis paper analyzes an induction motor with high temperature superconducter (HTS) coated slotted solid rotor. By slotting the solid rotor, the electromagnetic torque near synchronous speed will increase but the starting torque will decrease. To improve starting torque, rotor slots are coated with HTS materials. Using HTS material vary the rotor resistance to great extends in starting step and this means the starting torque will be maximized. Also the torque near synchronous speed will be higher than before because of the resistance of the HTS is completely zero in this period. This would help the torque become more than the case without any coating. It is concluded that, HTS coating of slotted solid rotor will increase the starting torque by 42 and 74% than smooth type rotor and slotted one, respectively. For case-study motor, the torque near synchronous speed these improvements were 75% and 33%, respectively. The performance of the proposed motor is simulated using finite element method (FEM).

Solid rotor induction motors (SRIMs) are asynchronous motors suited for high speed applications. This work presents an experimental case study where standard loss segregation procedures for induction motors are performed with a two-phase smooth solid rotor induction motor in order to verify their applicability. Even though the machine is supposed to operate at high frequency, the tests are performed at reduced frequency and voltage in order to avoid the effects of time harmonics. An adjustment in the separation of losses is proposed to contemplate the effects of the high no-load slip, and the behavior of the stray losses under high per-unit slip is analyzed in a load test. The test results are finally extrapolated for the rated condition.
