Custom Drives for Large Fans and Propellers

SPINNING SMALL FANS IS EASY. SPINNING LARGE FANS IS NOT. UNTIL NOW

 

C•Motive's drives deliver maximum torque and efficiency in the 100-2000 rpm range, where other motors need gearing, belts, or are just plain massive to get sufficient torque. C-Motive's drives deliver 3-10x more torque per kg of weight than competing motors, without a separate cooling system.
 
Fan and propeller drives using C-Motive's unique technology offer superior system-wide efficiency. The most efficient fans and propellers are large and spin slowly, and are well-matched to C-Motive's drive performance. Electromagnetic motors, however, are most efficient at much higher speeds, resulting in a poorly matched system with suboptimal efficiency over the entire operating range.
