Title: Brushless motor as a spindle ... And controll it with mach3
Post by: lampadas on January 10, 2014, 04:01:53 AM
Hi .. Can Anyone tell me how can I do this .....  I want controll a brushless motor with mach3

I have this esc ...http://www.helipal.com/hobbywing-skywalker-40a-esc.html (http://www.helipal.com/hobbywing-skywalker-40a-esc.html)


Look this ..

 Thanks .

What type of input signal does the speed controller require, PPM, PWM or just variable frequency?

Interesting question which I'm curious to hear a learned response to.  I've run R/C planes, boats & cars for 40 yrs without knowing much about the magic "behind the scenes."  This link explains a bit about how they work.  http://en.wikipedia.org/wiki/Servo_control

Seems like a simple task for Mach, yes? ;D

Here's the answer for non electronics wizards (such as myself) that can't build their own.  http://www.logicnc.com/rcnc.html

esc need pwm signal.. Every 20ms

I don't know if it is  simple task but I can do  the motor run... I  think mach doesn't  produce in this frequency pulses

I know this solution but it is not cheap.if you look the video this man use the brushles motor and the esc only . And some resistors . How can I make this

Not only resistors, kind of IC on the bottom.
1.5 to 2.5 msec pulsewidth PWM.
found this on YouTube

The Pokeys device has adjustable PWM outputs.

I think this is  PIC16F629 and I thing pg must be programmed ....

Yes, it look pretty much like that. Maybe worth a try.
Correction : 1 to 2 msec pulsewidth PWM ( not 1.5 to 2.5 as I mentioned before ) where 1.5 is the middle.
For some fun I tested it with a Pokeys56U, and yes its working. :)
