Design and Implementation of a Novel Magnetic Bevel Gear
Abstract
A magnetic gear offers several advantages compared to the mechanical gear due to the reduced
maintenance, higher efficiency than conventional gears and physical isolation between input and output
shafts. This paper presents a novel design of magnetic bevel gear that achieves high torque transfer to the load. The proposed gear design provides higher load torque under various gear configurations. The
various configurations include different air gap length, different pole pairs with the same gear ratio and gear dimensions.
A practical prototype magnetic gear model is developed and its torque performance is analysed and
compared with finite element analysis simulation method under various configurations. Also, the
performance of the proposed magnetic bevel gear is compared to mechanical bevel gear. Finally, it is
concluded that the results in this paper may help to initiate a shift from mechanical bevel gears to
magnetic bevel gears.
