NEO Brushless Motor


The REV NEO Brushless Motor is the first brushless motor designed to meet the unique demands of the FRC community. NEO offers an incredible power density due to its compact size and reduced weight. It designed to have similar performance characteristics and matching mounting features, NEO can be a drop-in replacement for CIM-style motors.  

NEO has been optimized to work with the REV SPARK MAX Motor Controller to deliver best-in-class performance and feedback. Brushless motors like the NEO can ONLY be driven using brushless motor controllers, and will be damaged if used incorrectly. Currently the only FRC legal brushless motor controller is the SPARK MAX.

This motor is perfect for your FRC Robot, Industrial platform or Warehouse robot,  Electric skateboards and more!
