The demands made upon electric motors continue to increase, and can often only be fulfilled by using special materials. This trend has grown significantly over the past few years, and we have therefore developed and installed our own coating facility for bonding varnish. The machines have been designed so that we can reliably coat all the different alloys of electrical steel sheet (and particularly cobalt iron alloys) regardless of the thickness of the sheet. The thickness of the coating is set within the µm range.
