About Us

Rapid Power Industries designs and manufactures OEM quality, specialised, innovative, high durability vehicle alternators.  


Our alternators produce significantly more output than existing standard alternators. These performances are achieved via:

  • Precision manufacturing
  • Rotor design, assembly and balancing
  • Stator design and assembly
  • Rectifier design, diode quality and assembly
  • Cooling fan design
  • Regulator quality


Rapid Power alternators are manufactured with precision machine tools. Crucial tolerances exceed industry standards. All design features are engineered beyond those of conventional alternators. Rectifiers are manufactured with high temp genuine Bosch Zener diodes mounted into highly efficient heat-sinks.

Electrical winding are assembled with C class insulation (200°C continuous rated). Rotors are balanced beyond industry standards. High temp C3 bearings are mounted into precision turned journals with heat-sink cooling. Alternators are designed for near maximum output and cooling efficiency at very low rotor RPMs.

Requests for custom and unique applications are welcomed.
