At EMCC/Thistle Industries we produce more V-Ring commutators than any other type. In this commutator, copper bars are insulated from each other and the steel core by segments of mica. Insulated steel V-rings are forced under pressure on to the dovetails machined into the commutator. Nuts or bolts are then tightened while under pressure locking the copper mica assembly in place.
V-ring commutators come in a wide variety of types and sizes. Some v-ring commutators may have an inserted riser with a vented steel core - while others may have a stepped bore with a key-way alignment. Often, moulded commutators that come to us are re-engineered and converted into a v-ring style commutator with a re-usable steel core. Having a re-usable steel core allows for more economical repairs and replacements (re-fill) in the future.
