Description
The MAXPlanetary 1:1 Brake Cartridge is a drop-in, self-contained module that instantly adds a reliable bi-directional unpowered hold for any MAXPlanetary gearbox. Designed around the principles of a sprag clutch, sometimes referred to as a torque diode, clutch, or overrunning clutch, this cartridge prevents backdriving in either direction by locking the output whenever the motor or input is stationary. The brake engages automatically when the output velocity exceeds the motor velocity, and it can be reliably released because the unlocking torque is approximately eighty percent of the locking load.
Once assembled into the MAXPlanetary System, the 1:1 Brake engages without the need for servos, pneumatics, or additional actuation. Inside, a set of precision-machined rolling pins and wedges generate a strong mechanical hold that keeps your mechanism in place the moment the motor stops rotating. This allows teams to reduce gear ratios, lighten mechanisms, and increase speed while still maintaining positional stability.
Ideal for end of game climbs and high-speed elevators, the 1:1 Brake Cartridge keeps systems locked in place while eliminating the need to hold position with motor power. This saves battery capacity and reduces motor heat throughout operation. Although the brake can be placed anywhere in a MAXPlanetary stack, we recommend locating it closest to the motor or input to maximize longevity over many seasons. It is not recommended for high moments of inertia like long lever-arms, flywheels, or launcher applications.
A steel internal ring housed in a lightweight aluminum case provides excellent strength and durability while maintaining a compact standard cartridge size. The cartridge integrates seamlessly with all other MAXPlanetary stages and occupies only a single slot.
For teams using three reduction cartridges, the brake remains fully compatible. This setup requires 2.5 inch socket head screws, which are not included in the MAXPlanetary Base Kit.
Super compact. Ultra lightweight. Completely automatic. Add the MAXPlanetary 1:1 Brake Cartridge to your elevator, climbing mechanism, or other application to gain dependable holding power with no added complexity.
