Hi,
I'm making a mill-turn center that needs a lot of motors to work. I know it's slightly off topic from electric vehicles, but the mill turn center will be used to manufacture custom electric vehicles, so...
Requirements;
-The main spindles of the machine need to be able to run in a speed range from 0 to around 3,000 RPM.
-The spindle will need 2kW or more at higher speeds when cutting metal.
-Low end torque preferable.
My plan is to use a low KV outrunner motor with a built in hall effect sensor, and drive it with a high voltage electronic speed controller powered by Lipos. For initial testing, I'll control it with a cheap servo tester. Eventually I'll control it with a CNC control board PWM signal. I have special absolute rotary encoders and I'd like to be able to do closed-loop position control using the outrunner motor eventually.
My main concern now is that I'm not that familiar with BLDC motors and controllers like most of the people on these forums. I'm fairly certain I need a hall effect sensor and a low KV BLDC motor, but the details and pitfalls are unknown to me. I'd like to be an expert on this subject eventually, but for now I'm new to it. I have access to 3d printers and CNC machines to make what I need; I can build some of my own hardware.
So, can anyone give me advice on what to buy for my project? I'm leaning toward this motor to start with;
