Abstract

A method is used to wind a toroidal core with a wire obtained from a magazine having a ring shape. The method includes winding the wire onto the toroidal core in a fixed winding plane, rotating the toroidal core during winding, the rotating being about an axis that is perpendicular to a plane of the ring shape of the magazine, and holding the toroidal core using a gripper that moves with the toroidal core during winding.
