The Power of Permanent Magnets, the Simplicity of AC Motors

Chorus directly attacks the hybrid price premium in ways that no competing technology can.

The Chorus Difference

The Chorus Motor's patented employment of electrical drive harmonics unlocks a power-to-weight ratio of almost 10:1 over conventional AC induction solutions. This incredible power density, and the use of patented control logic, allows the motor to function efficiently in both low-speed/high-torque and high-speed/low-torque configurations. In other words Chorus handles very fast starts and 'power jumps' as well as smooth, continuous high-speed operation with equal elegance.

As a high-phase order motor, the amount of current running through each phase is reduced, enabling a 20-30% reduction in the size and weight of the power electronics module.
