# Invenscience i00800 Torxis Servo 800 oz.in. 0.75 sec/90 deg **Type:** Product page · **SKU:** POLOLU-1391 · **Brand:** [Pololu](https://core-electronics.com.au/brands/pololu-australia) **Page:** https://core-electronics.com.au/invenscience-i00800-torxis-servo-800-oz-in-0-75-sec-90-deg.html ([markdown](https://core-electronics.com.au/invenscience-i00800-torxis-servo-800-oz-in-0-75-sec-90-deg.html.md)) ## Retired product This product is retired and no longer available for purchase. Search the catalogue for an alternative. ## Description The industrial-grade Torxis high-torque servos by [GearWurx](https://gearwurx.com/) (formerly know as Invenscience) are available in two different gear ratios that let you select for higher power or higher speed: - The **[i00600 Torxis](https://core-electronics.com.au/invenscience-i00600-torxis-servo-1600-oz-in-1-5-sec-90-deg.html)** can rotate 90° in 1.5 seconds while providing 100 lb-in (115 kg-cm) of continuous duty torque (200 lb-in peak torque). - The **[i00800 Torxis](https://core-electronics.com.au/invenscience-i00800-torxis-servo-800-oz-in-0-75-sec-90-deg.html)** can rotate 90° in 0.75 seconds while providing 50 lb-in (57 kg-cm) of continuous torque (100 lb-in peak torque). The servo is powered by 12 volts DC and draws approximately 3 A at full load. All of its gears are metal for increased durability, and the 3/8" hardened output shaft is supported by two ball bearings. It is pre-configured for a 90 degree range of motion, but this can be increased by reconfiguring the embedded controller (see the Bonus Feature section below for more information). The Torxis is controlled by the standard radio-controlled (RC) hobby servo signal used by most RC receivers and [servo controllers](https://core-electronics.com.au/breakout-boards-and-modules/motor-drivers-controllers/servo-controllers.html). | \| [![](https://a.pololu-files.com/picture/0J9816.500.jpg?bbc340c947e6fad5525a58673e75ff22)](https://a.pololu-files.com/picture/0J9816.1200.jpg?bbc340c947e6fad5525a58673e75ff22) \| \|---\| | \| [![](https://a.pololu-files.com/picture/0J9815.270.jpg?81ab0ed02ac8e8bcec931fa1630db48a)](https://a.pololu-files.com/picture/0J9815.1200.jpg?81ab0ed02ac8e8bcec931fa1630db48a) \| \|---\|---\| | |---| | \| [![](https://a.pololu-files.com/picture/0J9819.400.jpg?c4314d86e0ff1941f0fb4adc320443ce)](https://a.pololu-files.com/picture/0J9819.1200.jpg?c4314d86e0ff1941f0fb4adc320443ce) \| | \| [![](https://a.pololu-files.com/picture/0J9814.270.jpg?c830c55604df2dfc6a462e3da64572b7)](https://a.pololu-files.com/picture/0J9814.1200.jpg?c830c55604df2dfc6a462e3da64572b7) \| \|---\|---\| | |---| The servo includes a pre-mounted metal horn as shown in the pictures; the horn has eight 10-32 threaded mounting holes.

Power is connected via the Torxis’ two separate, heavier-gauge wires. The following video shows the i00600 Torxis servo lifting a 100 lb load as part of GearWurx’s servo cycle testing: **Dimensions** These servos are much larger than typical RC hobby servos and weigh approximately 2.2 lb (1.0 kg). The diagram below shows the dimensions of the Torxis servo. | [![](https://a.pololu-files.com/picture/0J9840.500.jpg?b8f39881f3ae203f5de6a75f5258183f)](https://a.pololu-files.com/picture/0J9840.1200.jpg?b8f39881f3ae203f5de6a75f5258183f) | |---| | Torxis i0060 and i00800 servo mechanical dimension diagram. Units are inches. | **Applications** The Torxis servo’s power makes it suitable for ultra-high-torque applications that previously required custom feedback control systems including: - Unmanned ground vehicle controls - Factory automation and valve actuation - Heating ventilation and air conditioning airflow controllers - Solar panel sun tracking - Opening and closing gates and windows | [![](https://a.pololu-files.com/picture/0J9820.300.jpg?f31a4771d04cf5e0700c878045bc2c6d)](https://a.pololu-files.com/picture/0J9820.1200.jpg?f31a4771d04cf5e0700c878045bc2c6d) | |---| | Removing the end cap of the Torxis servo reveals a Jrk 21v3. | **Bonus feature: there’s a [Jrk](https://core-electronics.com.au/pololu-jrk-21v3-usb-motor-controller-with-feedback.html) inside!** The Torxis servo is controlled by an embedded [Jrk 21v3](https://core-electronics.com.au/pololu-jrk-21v3-usb-motor-controller-with-feedback.html), a highly-customizable USB motor controller that also offers serial, analog, and USB interfaces. Using the free Jrk Configuration Utility, parameters including range, response curves, speed or current limits, and much more can be customized for your application. The Jrk enables the Torxis servo to function as a USB-controlled servo while allowing the host computer to monitor and graph position, current, and other parameters in real time. For more information about these features, please see the Jrk 21v3 user’s guide. | [![](https://a.pololu-files.com/picture/0J1749.300.jpg?34f9d694bce687106e387746a9c9a42e)](https://a.pololu-files.com/picture/0J1749.1200.png?34f9d694bce687106e387746a9c9a42e) | |---| **People often buy this product together with:** | [![i00600 Torxis Servo 1600 oz.in. 1.5 sec/90 deg](https://a.pololu-files.com/picture/0J9818.100.jpg?ff03fcdf1a477193bb3b47ea1ee22d56)](https://core-electronics.com.au/invenscience-i00600-torxis-servo-1600-oz-in-1-5-sec-90-deg.html) | [i00600 Torxis Servo 1600 oz.in. 1.5 sec/90 deg](https://core-electronics.com.au/invenscience-i00600-torxis-servo-1600-oz-in-1-5-sec-90-deg.html) | |---|---| **Dimensions** | Size: | 5.50" x 2.40" x 4.66" | |---|---| | Weight: | 2.2 lb | **General specifications** | Digital?: | Y[1](https://core-electronics.com.au/#note1) | |---|---| | Speed @ 12V: | 0.5 sec/60° | | Stall torque @ 12V: | 1600 oz·in[2](https://core-electronics.com.au/#note2) | | Stall torque @ 6V: | 800 oz·in[3](https://core-electronics.com.au/#note3) | | Reverse voltage protection?: | Y | | Hardware included?: | N[4](https://core-electronics.com.au/#note4) | | Lead length: | 12 in | **Notes:** 1Serial and USB interfaces also available.2The continuous duty torque rating for this product is 800 oz-in.
