FingerTech FT1806 750KV Brushless Motor

Upgraded Sept '25: The shaft is now increased to 3mm internally! The output is stepped down to 2mm to accept a standard pinion gear. The e-clip is on the 3mm portion, so it is no longer a weak point in this type of motor design when using this as a weapon motor in a 150g robot!  

This is the FT1806-750KV motor used in our Brushless Mega Spark Gearmotors.  Use it as a replacement for battle-damage, or in your own creation.

Prior to Sept '25: Specially designed to use a shaft collar instead of an e-clip which creates a weak point in the shaft of other motors.

Motor Specifications:

- Max Current @12V: 10A
- Stall Torque: Notes about Brushless Motor Torque
- No-Load Current (with Mega Spark gearbox): 1.1A
- Recommended ESC: BL40A-R Reversing AM32 Brushless ESC for use as a drive motor - AM32 firmware is smoother at low speeds.

- Shaft Length: 9.6mm (0.38in)
- Weight: 25.3g (0.89oz)
- Diameter: 23.1mm (0.91in) (slightly smaller than a 24mm gearbox, so it won't rub on a sidewall if flush mounted)
- Length (back to face): 18.5mm (0.73in)
- Motor Wires: 10cm long 26AWG with 3.5mm bullet connectors
- If you require a new pinion gear to match the Mega Spark planetary gearbox, they are here: (11T Pinion) (One pinion comes with the gearbox if you are buying that already.)
