This manuscript presents a novel brushless wound rotor synchronous machine (BL-WRSM) utilizing an inherent subharmonic component (SHC). The proposed design achieves a brushless function by utilizing ...

DeepDrive’s dual-rotor design promises material efficiency and range improvements but remains in the lab. In contrast, Donut motors are already in production. The company’s motorcycle motors ...

But they still carried on with Rotor as well until relatively recently. Now the two are back together with an all-new brand, leveraging much of their design, engineering & manufacturing knowledge to ...

Firstly, the structure and operating principle of the multi-shaped magnet rotor are presented. And the magnetic field and average torque of the MMR design are formulated mathematically through field ...
