Python to Raspberry Pi to Seeduino to DC Brushless Motor?

Using Arduino Motors, Mechanics, Power and CNC
#1

Hello,

I'm new to Arduinos and Motors and PWM. I was wondering if someone could give me a hint on how I can control a dc Brushless motor (3 wires) with my seeduino and Raspberry Pi??

If you guys could provide with some steps and sources to how I can get the motor to start spinning.... It's a pretty big motor, about the size of an adult mens arm so I'm not sure if I'll need an external power supply and if so how I can do that?

Wiring/coding etc.

Thank you very much in Advance for any help!

Is this an RC brushless motor without hall-sensors? If so then you need an ESC and use the Servo library to control it.

The arduino should be asked to supply no more than 40mA from an output pin.do you expect a motor that size to take that little current? Yes you need an external supply and driver.
