About Us






specialised DC alternators produce high outputs at very low rotor RPM.

Brisbane, Australia






The Rapid-Power mining duty alternators have been developed to provide serious durability in extremely demanding conditions. These alternators have many unique and unprecedented design features.

The first and foremost feature is the bearing seals, the bearings are sealed with special labyrinth frictionless seals, these seals provide complete ‘sealed for life’ protection. The bearings in the alternators have massive load ratings many times beyond the required minimum. The brush-less rotors are balanced to very high standards, which significantly further extends bearing life. The rectifiers are manufactured with 215ºC rated diodes inserted into exceptionally large heat sinks and all connections are welded. The electrical windings have several coats of silicon-based varnish, which provides significant thermal and mechanical protection. The regulator “ floats“ in a thermally conductive potting compound to reduce the effects of vibration. The housings are manufactured from 6000 series aluminium that provides much greater mechanical strength than conventional cast alloy housings. The housings have replaceable steel mounting legs for further strength and durability. All electrical connections are via pre wired Deutsch plugs and a field isolation facility is provided.

The Rapid-Power corrosion resistant mining duty alternator has been developed for continuous use in highly corrosive and dusty environments. The rectifier and regulator are potted in thermal adhesives for complete environmental protection. The stator and field windings are coated in special resins with high intrinsic mechanical and thermal protection. The alternators have a brush-less design and the bearings are sealed with labyrinth frictionless seals, which offer complete protection from dust and water. The alternator housings are machined from 6000 series aluminium and are then black anodised. All steel parts are double zinc coated.
