Hybrid Electromagnetic Brakes: Design and Performance Evaluation

Abstract: Eddy current brakes having advantages such as contactless operation offer an alternative to conventional frictionbased brakes. The flux source in an eddy current brake can be produced by permanent magnets or electrically excited windings. The former eliminates the need for an external supply, whereas the latter provides good control capability for the device. Herein, in order to take the advantages of both mentioned types, a hybrid electromagnetic brake is introduced, and the corresponding design guidelines fo… Show more

“…The main specialty of this magnetic brake is there is no mechanical contact with the rotor for controlling the speed of the turbine. Therefore, ASTESJ ISSN: 2415-6698 this eddy current brake system is an alternative method to the conventional friction-based brake system [6]. Also, magnetic brake system required less maintenance than the conventional brake system [7].…”

“…In electrical machines design, numerical methods such as finite element analysis (FEA) have been generally used for shape optimization [12], and torque improvement [13]. Even though the analysis can be achieved by the numerical methods, the analytical solutions can facilitate the optimal design procedure [14,15].…”
