Disc Motor: Conventional and Superconductor Simulated Results Analysis

Abstract

Abstract. Taking into consideration the development and integration of electrical machines with lower dimensions and higher performance, this paper presents the design and development of a three-phase axial flux disc motor, with 50 Hz frequency supply. It is made with two conventional semi-stators and a rotor, which can be implemented with a conventional aluminum disc or a high temperature-superconducting disc. The analysis of the motor characteristics is done with a 2D commercial finite elements package, being the modeling performed as a linear motor. The obtained results allow concluding that the superconductor motor provides a higher force than the conventional one. The conventional disc motor presents an asynchronous behavior, like a conventional induction motor, while the superconductor motor presents both synchronous and asynchronous behaviors.

Experimental Characterization of a Conventional (Aluminum) and of a Superconducting (YBCO) Axial Flux Disc Motor

“…In this paper, the relations between the equivalent circuit's parameters and the motor's characteristics are discussed, for a conventional induction disk motor and for a HTS hysteresis disk motor, composed by a rotor with a polycrystalline YBCO disk [27]. As it happens with conventional squirrel cage induction motors, the rotor quantities can only be inferred from the measurement of the stator quantities.…”

“…The topology, fabricated issues and the operating principle of both the conventional induction and HTS hysteresis disk motors can be found in [27], [28].…”
