Have you been looking for an easy way to create a high power spinner on your next beetleweight? Want a mechanically robust hub motor that ties your frame rails together? Tired of worrying about belts and pulleys? The Repeat 2812 hub motor has been custom designed for the combat robotics community, with guidance from many award winning builders with 20+ years of combined hub motor experience. This motor has been tested by top bots across the US and now you can benefit from the reliability and durability of a custom hub motor for a fraction of the price!
Tech specs:
- Stator size: 2812
- Weight
- 175g without wires
- 182.5g with full length wires
- 195.6g with blade mounting hardware
- Large 6805 and 6000 bearings
- Ring bearing held in by 2x M3 screws
- M4x18.5mm motor mount pattern
- M5 weapon mount screws
- Works with blades from 1/8” thick to 1/2” thick.
- Overall dimensions: 2.28in max diameter by 1.375in length
- Comes with battle hardened magnet ring (also available separately)
- Magnet ring can be removed via 4x 3mm pins
- Extra long wires to span even the widest of robots.
- 3 kv options: 800, 1300, 1800
- Recommended for 3S-6S usage. Be sure to choose your kv for a reasonable tip speed to avoid burning out your motor.
Notes for use:
- 5/16″ shoulder bolt or other similar through shaft is required for use. Without the shoulder bolt the rotor is not fully constrained and may be damaged.
- When designing the blade, the tooth portion should line up with the 2 screws at the top. This provides the most optimal loading scenario with maximum strength. Three tooth weapon designs are not recommended.
The motors have been tested on the following bots:
- Elytra
- Nautiloid
- Prince
- Rorschach
- Venator
- Je ne sais quoi
