VariPole

Advanced Hybrid has developed a new, revolutionary electric motor. Nearly all 3-phase AC induction motors used in industrial applications today are based on a landmark design invented by Nikolai Tesla in the late 19th century. As a result of its innovation in designing the sCVT and DGM, Advanced Hybrid has “re-invented” the conventional stator/rotor arrangement with more advanced controls to produce a new, high-efficiency electric motor which it calls the VariPole.

The new motor is a hybrid

The new motor is a hybrid

it is both an electric motor and gearbox combined. Its features include:

  • Use of stators and rotors similar to current induction motors, which means reduced retooling costs and design times for manufacturers that adopt the technology
  • No permanent magnets required resulting in low cost, mass producible and robust components
  • Rotor induction operates using electromagnetic torque but is not limited by slip which significantly reduced energy losses in the motor especially at low speeds and part loads
  • Advanced software controls to manage/change speed and torque while maintaining full power supply to the windings, therefore voltage is not reduced (when frequency is reduced) at slow speeds like for VFDs.  The VariPole does not suffer the losses and experience heat issues
  • Compared to conventional induction motors, the VariPole has much more power at part loads and slow speeds and much higher efficiencies, especially at part loads or slow speeds with an almost “flat” efficiency curve
