Abstract
The electromagnetic winding is made up of a plurality of insulated coils which are formed by a wound-up sheet metal strip. The strip is of a material having high magnetic permeability so that the coils eliminate the need for a magnetic core. The coils can be insulated from each other by a wound strip of insulating material such as paper or by means of a synthetic lacquer. The electromagnetic coupler can be of the synchronous or asynchronous type and can be in the form of a clutch or brake.
