Title:
ELECTROMAGNETIC ROTARY DRIVING DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/204077
Kind Code:
A1
Abstract:
[Problem] In prior-art electromagnetic rotary driving devices, two permanent-magnet rotors are disposed in proximity to each other on the lateral side part of an iron core part of a fixed magnet, which has presented a problem in that magnetic forces from permanent magnets on the outer periphery of the permanent magnet rotors interact and prevent smooth rotation. [Solution] An electromagnetic rotary driving device in which thin and long branch magnets 3, 4 are provided spread in a plurality of branches at an end of the iron core part 2 of a fixed magnet 5, and permanent magnet rotors 10 facing the end surface of the branch magnets 3, 4 are set apart from each other, making it possible to prevent the permanent magnets 11 of adjacent permanent magnet rotors 10 from interacting and preventing smooth rotation.
