(Query form `cart/link.md?items=...` also works but some robots parsers refuse query strings here.) - **Checkout** is completed on-site and includes a captcha at the payment step. Share the cart link; checkout takes it from there. - **Search the catalogue:** `https://core-electronics.com.au/search/{query}.md` (URL-encode the query; pages 2-3 at `search/{query}/{page}.md`; `search.md?q=` also works) - **Payment methods, purchase orders, policies and contact details:** https://core-electronics.com.au/llms.txt ## Description This 99.5:1 ratio 5303 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 180 RPM when 24VDC is applied. While this motor’s nominal voltage is 24V, you can give it plenty of punch with the ever-convenient 20V power tool battery system! The positive drive 8mm REX™ shaft 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. The 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. ### Downloads - [ Spec Sheet ](https://core-electronics.com.au/attachments/localcontent/5303-2402-0100_spec-sheet_1078988fb56.pdf) - [ STEP File ](https://core-electronics.com.au/attachments/localcontent/5303-2402-0100_25416ff700b.zip) ### Specs | Motor Size | RS-560 | |---|---| | Motor Type | Brushed DC | | Nominal Voltage | 24VDC | | Output Shaft | 8mm REX™, 23.5mm Length | | Gearbox Style | Planetary | | Nominal Gear Ratio | 99.5:1 | | Gear Ratio Formula | (1+(46/17)) \* (1+(46/11)) \* (1+(46/11)) | | Gear Material | Steel | | Wire Length | 470mm (including connectors) | | Wire Gauge | 18AWG | | Motor Connector Type | 3.5mm FH-MC Bullet Connectors | | No-Load Speed | 100 RPM @ 12VDC 160 RPM @ 20VDC 180 RPM @ 24VDC | | No-Load Current | 0.8A @ 12VDC 1A @ 20VDC 1.3A @ 24VDC | | Stall Torque | 2790 oz-in (201 kg.cm) @ 12VDC 3810 oz-in (274 kg.cm) @ 20VDC 4819 oz-in (347 kg.cm) @ 24VDC | | Stall Current | 30A @ 12VDC 45A @ 20VDC 60A @ 24VDC | | Maximum Duty-Cycle at Rated Torque | 25% on, 75% off (Maximum 15 minutes Continuous) | | Rated Torque | 501 oz-in (36.1 kg.cm) @ 12VDC 680 oz-in (49.3 kg.cm) @ 20VDC 867 oz-in (62.4 kg.cm) @ 24VDC | | Speed at Rated Torque | 82 RPM @ 12VDC 131 RPM @ 20VDC 148 RPM @ 24VDC | | Current Draw at Rated Torque | 6A @ 12VDC 8A @ 20VDC 11A @ 24VDC | | Encoder Type | Relative, Quadrature | | Encoder Sensor Type | Magnetic (Hall Effect) | | Encoder Voltage Range | 3.3-5VDC | | Encoder Resolution | 2786.2 PPR at the Output Shaft | | Encoder Resolution Formula | (1+(46/17)) \* (1+(46/11)) \* (1+(46/11)) \* 28 | | Encoder Connector Type | 4-Pos JST XH \[FH-MC\] | | Weight | 542g | | IP | Patented | ## Images - [Product image 1](https://core-electronics.com.au/media/catalog/product/G/B/GB-5303-2402-0100-1.jpg)
