ELECTROMAGNET FOR RADIAL MAGNETIC BEARING

摘要

PROBLEM TO BE SOLVED: To miniaturize a bearing and increase its electromagnetic capacity by raising a line moment for a electromagnet coil of a controlled system radial magnetic bearing which holds a radius direction location of a shaft to a regular position with electromagnetic force. SOLUTION: The winding section form of electromagnet coil is to be under the opening width of the groove of the electromagnetic core, and the electromagnet is composed of the rectangular section coils being close to this width and the triangle section coils having the base under the above opening width being close to this width which are alternately arranged.
