EMCC manufactures various types and sizes of commutators, including Glass Banded Commutators. We can rebuild, re-fill, repair to OEM specifications. \u00a0With over 35 years of experience manufacturing Glass Banded commutators; we have built a reputation for consistent quality and reliability.<\/p>

Typical Glass Banded Commutators differ from V-ring style Commutators. V-ring Commutators have steel V-rings insulated with mica that holds the copper & mica assembly together while under pressure. Since the pressure is only applied at both ends of the segment pack, vibration and lifting can occur if the copper bars required are to be quite long.<\/p>

Glass Band Commutators are often lighter in overall weight than their V-ring style counterparts. The steel core on a V-ring type Commutator is often thicker because of the space needed for steel V-rings and anchoring nut\/bolts.<\/div>
\u00a0<\/div>
On a Glass Banded Commutator, the copper assembly is interference fitted over an insulated steel barrel. The grooves are machined into the segment pack while a shrink ring holds the assembly in place over the steel hub. Grooves are positioned to add strength and stability while not interfering with brush track positioning.<\/div><\/div>

In a Glass Banded Commutator construction, resin-glass banding (comprised of high tensile glass yarns) is applied under tension to cut grooves along the surface of the copper bars. The resin glass bands are cured. Therefore, keeping the copper segments compressed and held in place by the resin glass bands. The number of glass bands and their placement can vary depending on bar length, brush placement, and overall motor design.\u00a0<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t

EMCC can manufacture Shrink-fitting Glass Banded Commutators to a dovetailed v-bound commutator with a steel V-ring style core (where applicable).<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Shrink-Fit Glass Banded Commutators are advantageous in certain use cases where overall weight and airflow are a consideration. However, in some applications, they carry more disadvantages than advantages. Glass Banded Commutators are difficult to repair, cannot be re-insulted, and can be susceptible to failure in high heat and contamination environments due to the banding.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Some countermeasures can be applied to the banding in the final stages of construction, but often these are not enough. In these situations, a glass banded to V-ring conversion may be considered. Converting a Glass-Banded Commutator to a V-Bound \/ V-ring type Commutator is not always a viable or possible solution. Many factors must be considered before attempting this type of re-construction for an aftermarket application. Weight, copper segment length, armature airflow, venting, and cost are all factors that must be examined by our qualified engineers.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t
