Armature Coils

Our Armature coils excel above all others. Each coil is hand-crafted with attention to the finest details and precisely formed to final dimensions based on over 100 years of experience, accumulated winding data, patterns, & tooling. Re-enforcing insulation is carefully applied to all potential electrical and mechanical stress points, and each armature coil is tested and inspected prior to shipment. Our extensive library of winding data includes designs for over 20,000 different machines of all types, with ratings from 1 HP through 30,000 HP.

We manufacture all Sure-Fit armature coils according to our tailor made patterns at our plant, so winding goes faster at yours. No need for you to spend hours shaping and adjusting coils to your armatures, because pitch and dimensions are exact the minute they arrive.
