The MAXPlanetary System is a cartridge-based modular planetary gearbox designed from the ground up for NEO-class motors. The design of the MAXPlanetary has been carefully optimized to provide torque density unavailable in FRC up until now.
The MAXPlanetary System is intended for use with the NEO Vortex Brushless Motor, NEO Brushless Motor, Falcon 500, Kraken X60, and CIM motors. It also supports NEO 550 and 775 size motors (775pro or AM RedLine). Building on the ability to iterate and adjust designs easily, the MAXPlanetary System consists of lubricated cartridges allowing for swapping gear ratios on the fly and with ease. Users can configure a single-stage planetary using one of three different reduction cartridges or build multi-stage gearboxes through stacking individual cartridges together. The user can use the included 1/2in hex shaft or use a custom length of hex shaft best suited for the application. The gearbox also provides two mounting options, face mount and side mount, for ultimate flexibility in your robot design.
The MAXPlanetary Base Kit (REV-25-2109) is the entry point into using the MAXPlanetary System. This base kit includes a universal input stage, 1/2in hex socket output, hardware pack, 8mm keyed input coupler kit, and a 1/2in rounded hex shaft. Purchase a MAXPlanetary 3:1 Cartridge (REV-21-2101), MAXPlanetary 4:1 Cartridge (REV-21-2102) or MAXPlanetary 5:1 Cartridge (REV-21-2103) to complete your system. Add a NEO Brushless Motor (REV-21-1650) or an adapter kit if you want to use a different motor, like the new MAXPlanetary 14T Spline Input Coupler (REV-21-2124) or MAXPlanetary 15T Spline Input Coupler (REV-21-2138).
The following torque measurements are for a static load condition (i.e. not moving). The torques listed are for the output of the stage.
NOTE: Cantilevered (sideways) load on the output shaft puts additional stress on the gearbox and will reduce the torque the gearbox can take. In addition, shock loads can cause the gearbox to fail in situations where the steady-state torque is still within allowable limits.
The following chart shows which gear cartridge configurations are allowable with different motors. Cells shown in GREEN are allowed, the cells shown in YELLOW will function but are not recommended, and cells shown in RED are not allowed.
These ratings are based on the default current limit on the SPARK MAX (or Talon FX). Increasing the current limit increases the maximum torque the motor can produce and may put components of the gearbox outside of their load rating.
