Chorus motors offer 10 times the overload torque of a traditional AC induction drive.

Your vehicle, of whatever size, can have remarkable torque in a compact package.

Chorus motors are based on AC induction technology. Unlike Permanent Magnet machines, their performance is not significantly constrained by overheating.

They don't need another engine for increased load.

Chorus motors don't use rare earths and can be manufactured by your existing suppliers under license.

Your costs can be lower and more predictable.

1. Chorus motors can be air-cooled, eliminating weight and expense.
2. Chorus motors have a 'virtual transmission', eliminating a major source of inefficiency and complexity.
3. Chorus motors facilitate series hybrid technology, dramatically simplifying drivetrains.

PM Machines overheat at highway speeds. Under increased load they require internal combustion engines to pitch in.

PM Machines require rare earths which are costly and have sourcing risks. This White Paper documents these risks related to Neodymium.

PM Machines can't be used for series hybrids, as they require cumbersome drivetrains, transmissions, and cooling systems.

Conventional AC induction machines can either be small, or powerful. Chorus can be both.

Conventional AC induction machines require complicated gearing to reduce motor size.

Other technologies often require serious engineering compromises, making for more complex systems.
