I have been trying to design a DIY Spindle for milling aluminum. I came across this DIY Spindle
[ame="http://www.youtube.com/watch?v=fPLdHeRQp_w"]YouTube - DIY 3-Phase Spindle for your cnc[/ame]
The Designer is using Brushless Motor (used by RC Airplane hobbyists)
Motor Specs (from the Manufacturers Page)
Power 110 Brushless Outrunner Motor, 295Kv
Overview
The Power 110 is designed to deliver clean and quiet power equivalent to or surpassing the power of a 110-size 2-stroke glow engine for sport and scale airplanes weighing 9 to 15 pounds (4 to 6.8 kg), 3D airplanes up to 11 pounds (5 kg), or models requiring up to 2000 watts of power.
Key Features
* Equivalent to or surpassing the power of a 110-size 2-stroke glow engine for 9–15 lb (4–6.8 kg) airplanes
* Ideal for 3D airplanes up to 11 lb (5 kg)
* High-torque, direct-drive alternative to inrunner brushless motors
* Includes mount and mounting hardware
* High-quality construction with ball bearings and hardened 8mm steel shaft
* Includes two 12mm prop shaft adapters tapped out for 10–32 threads
* Ideal for models requiring up to 2000 watts of power
* External rotor design for better cooling
The motors are pretty compact and can do High RPMs. Also we could hook up an encoder to the shaft for RPM control. Everything looks promising but I am not sure about the CONTINUIOUS OPERATION CAPABILITY of these motors since most RC Planes only fly for around 15-20 mins.
- I was wondering if such motors can be used as spindle motors?
- If anyone has experience using these motors please share your experiences/Ideas.
- Also please share your ideas on other suitable types of Motors for a DIY Milling spindle.
Thank You
