Abstract
Disclosed is a permanent magnet rotor magnetic coupling based on a double-sided stepped structure and a three-dimensional Halbach magnetic pole arrangement, including a conductor outer rotor assembly (), and a magnet inner rotor assembly (). The conductor outer rotor assembly () includes a right outer rotor assembly (), and a bearing connected to the right outer rotor assembly (). The right outer rotor assembly () includes a right conductor yoke (), and multiple conductive rings. The magnet inner rotor assembly () includes a right inner rotor assembly (), and a bearing connected to the right inner rotor assembly (). The right inner rotor assembly () includes a right magnet yoke (), and multiple magnetic rings. A stepped structure adopted by the present disclosure can make magnetic blocks have multiple polarity arrangement modes, thereby generating multiple different spatial magnetic field distributions, which are used in scenes with different power transfer requirements.
