HD Hex Motor No Gearbox

The HD Hex series motors and gearboxes feature integrated encoders and power that plug right into the Control Hub (REV-31-1595) and Expansion Hub (REV-31-1153). The gearbox options feature 5mm Hex output or coupler making it easy to connect gears, sprockets, wheels, etc. Encoder and power cables are included with motor. The HD Hex Motor is similar in size and power to other brushed 550 class motors with more convenient output options and connectors.
The pinion that is installed on this motor is compatible with the 40:1 Hex Gearbox (REV-41-1065) and the 20:1 Hex Gearbox (REV-41-1064), but NOT compatible with the UltraPlanetary Gearbox (REV-41-1600). Check out the 550 Motor Pinions page if transferring power to another gearbox type is needed.
