The 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. As it is designed to have similar performance characteristics and matching mounting features, NEO can be a drop-in replacement for CIM-style motors. This motor is perfect for your FRC Robot, Industrial platform or Warehouse robot, Electric skateboards and more!

NEO has been optimized to work with the 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.

New features were added to increase mounting options and usability for teams, including:

A tapped #10-32 hole was added to the end of the shaft, allowing teams to retain pinions on the shaft without the need for an external retaining ring.
A tapped #10-32 hole was added to the back housing of the motor. When a #10-32 x 3/8in long socket head screw is inserted into this hole and tightened finger tight, this screw supports the internal shaft while pressing pinions, making it no longer necessary to remove the motor housing to press pinions.
Additional holes were added to the front face of the motor, which allows for more flexibility in orientation when mounting the motor.
