## Description

This 50.9:1 ratio 5304 Series Saturn Planetary Gear Motor consists of a 24V brushed DC motor driving a 36mm diameter planetary gearbox. It runs at a no-load speed of 360 RPM when 24VDC is applied. While this motor’s nominal voltage is 24V, 20V gives it plenty of punch and allows you to use the ever-convient 20V power tool battery system.

Its positive drive 8mm REX™ shaft, which can be supported by an 8mm round bore bearing, has compatibility with a huge variety of goBILDA® motion components. Additionally, this motor’s specially-designed gearbox head allows for direct attachment to goBILDA® components in numerous use-cases made possible by its convenient shape.

Its two power wires provide plug-and-play compatibility with goBILDA® motor controllers via 3.5 bullet connectors. You don’t need to use the encoder during normal operation, but you can tap into it with a JST XH plug to bring position and velocity control to your project.

**??WARNING: Stalling this motor may cause irreparable damage!**This motor is extremely high-power. Use extreme caution when using it in applications with hard limits, such as linear slides and rotating arms.
