MAGNETIC GEAR DEVICE AND ROTATING ELECTRICAL MACHINE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18276448 titled 'MAGNETIC GEAR DEVICE AND ROTATING ELECTRICAL MACHINE

Simplified Explanation

The present disclosure describes a magnetic gear device and a rotating electrical machine with intermediate cylindrical portions that have increased rigidity against radial-direction external forces. The intermediate cylindrical portion includes magnetic-pole portions, frame-shaped spacers, end plates, and reinforcement portions to enhance the overall structure.

• Magnetic-pole portions arranged in a circumferential direction
• Frame-shaped spacers penetrating in the radial direction, arranged alternately with the magnetic-pole portions
• End plates provided at both ends of the magnetic-pole portions and the spacers in an axial direction
• Reinforcement portions placed inside the spacers to apply forces in the circumferential direction to the adjacent magnetic-pole portions via the spacer

Original Abstract Submitted

Provided are a magnetic gear device and a rotating electrical machine having intermediate cylindrical portions with increased rigidity against radial-direction external forces. In a magnetic gear device and a rotating electrical machine according to the present disclosure, an intermediate cylindrical portion includes: magnetic-pole portions arranged in a circumferential direction; frame-shaped spacers penetrating in the radial direction, arranged in the circumferential direction alternately with the magnetic-pole portions, and each having two side-wall portions contacting with the adjacent magnetic-pole portions; end plates provided at both ends of the magnetic-pole portions and the spacers in an axial direction of a rotary shaft; and reinforcement portions placed inside the spacers while being pressed to inner surfaces of the side-wall portions in the circumferential direction, to apply forces in the circumferential direction to the adjacent magnetic-pole portions via the spacer.
