hi, i just bought a rc airplane brushless motor 12 volt, it has 3 wires now i want to run that motor without controler with my arduino is that possible?
thanks tom

not someting like this? i want to program my own scp i thought this could work:
//have a good one
int sensorPin = A0; // select the input pin for the potentiometer
int sensorValue = 0; // variable to store the value coming from the sensor
int ledPin = 7; // LED connected to digital pin 9
int ledPin1 = 8;
int ledPin2 = 9;
int ledPin5 = 5;
int val = 0; // variable to store the read value
void setup()
{
pinMode(ledPin, OUTPUT);// sets the pin as output
pinMode(ledPin1, OUTPUT);// sets the pin as output
pinMode(ledPin2, OUTPUT);// sets the pin as output
TCCR2B = TCCR2B & 0b11111000 | 0x01;
}
void loop()
{
analogWrite(ledPin, 255);
delayMicroseconds(1000);
analogWrite(ledPin2, 0);
delayMicroseconds(1000);
analogWrite(ledPin1, 255);
delayMicroseconds(1000);
analogWrite(ledPin, 0);
delayMicroseconds(1000);
analogWrite(ledPin2, 255);
delayMicroseconds(1000);
analogWrite(ledPin1, 0);
delayMicroseconds(1000);
}
The only reasonable way to run a brushless 3-phase RC motor is to use an ESC and control it using PWM from the Arduino. An ESC is a rather complex device and not worth trying to duplicate in an Arduino.
whell i stil want to build one i think i got it you need to pulse minus to to make it work
you need 6 irf's 3 connected to ground and 3 connect to dc plus then pulsse in right combination and i think that will work, i'll let you know when i have all component and tested it
You also need to sense when to switch windings and PWM at 8KHz to maintain the desired speed via the input PWM.
thanks, i think i go without the sencor in and let it run at 1 speed thats all i want but i want to control the pulses to make them more energy effective
