NEO 550

NEO 550 Motor Overview

The REV NEO 550 (REV-21-1651) Brushless Motor is the newest member in the NEO family of brushless motors. Its output power and small size are specifically designed to make NEO 550 the perfect motor for intakes and other non-drivetrain robot mechanisms. Mounting holes and pilot match a standard 550 series motor, making it natively mount to many existing off-the-shelf gearboxes.


  • Mounting features match 550 series DC motors
  • Out-runner construction (Rotor housing compatible with REV Motion Pattern - Mount metal Gears, Sprockets, and Pulleys)
  • Front and rear ball bearings
  • High temperature neodymium magnets
  • High-flex silicone motor wires
  • Integrated motor sensor (3-phase hall sensors)
  • Motor temperature sensor

Check out the NEO 550 Motor Data Sheet for additional specifications and charted motor curves as well as the NEO 550 Motor Locked Rotor Testing and please make sure you have read and understand how to set the SPARK MAX Smart Current Limit

Wiring Connections

Connecting the NEO Brushless motors is fairly straightforward, follow the guide Wiring the Spark Max with the NEO Brushless Motors and don't forget to connect your encoder sensor wire, the motor will not spin without it!
Please note, improperly wiring the connectors can cause severe motor damage and is not covered by the warranty, DO NOT connect the motor directly to the battery


UltraPlanetary Gearbox kit (REV-41-1600) for the NEO 550 (REV-21-1651) is available. The kit comes with UltraPlanetary Cartridges to support six different final gear reductions ranging from nominally 3:1 to 60:1 (125:1 w/optional cartridges) allowing for the right amount of torque for the application at hand.
Pictured Above
UltraPlanetary Gearbox (REV-41-1600) is available with cartridge based gear reductions from 3:1 all the way up to 125:1
SPARK MAX Motor Controller (REV-11-2158) Our NEO 550 Brushless Motors have been optimized to work with the SparkMax to deliver best-in-class performance and feedback
The 550 Motor Pinions (REV-41-1608) are used for transferring power from a 550 class motor, like the NEO 550, to a gear, pulley, gearbox, etc,.
