Abstract:

An HTS induction motor, with an HTS squirrel-cage rotor, is analyzed using an electrical equivalent circuit. The squirrel-cage winding in the rotor consists of rotor bars and end rings, and both are considered to be made of HTS film conductors. A wide range of electric field versus current density in HTS film is formulated based on the Weibull function, and analyzed as a non-linear resistance in the equivalent circuit. It is shown that starting and accelerating torques of the HTS induction motor are improved drastically compared to those of a conventional induction motor. Furthermore, large synchronous torque can also be realized by trapping the magnetic flux in the rotor circuit because of the persistent current mode.
