Bldc motor driver circuit arduino.
We are using a bldc motor of rating model.
I have been doing it for quite long.
12 a 60 s the arduino code is as follows please guide me what am i doing wrong int a.
I have tried many combinations but the motor is not rotating.
Bldc motor control with arduino.
Once it moved for 7 turns.
Sensorless bldc motor control with arduino diy esc brushless dc motor controller using arduino and ir2101.
A 100k pull up resisto r is used at pin 1 of drv10866.
The first link contains more details about this project.
This bldc motor is the spindle motor of the cd rom driver and i chose it because it doesn t consume high power which can be easily driven by the l6234 driver.
There are a few ways to drive a brushless motor.
Then we connect pins 2 4 7 6 of drv10866 to common phase a phase b phase c of the bldc motor.
The controller can run the motor in the tow rotation directions cw ccw and the speed can be controlled using a potentiometer connected to a0.
Arduino forum using arduino motors mechanics.
The main design difference between a brushed and brushless motors is the replacement of mechanical commutator with an electric switch circuit.
I wrote the below arduino uno code to control a sensored bldc motor using the attached schematic diagram circuit.

The circuit diagram for brushless dc bldc motor driver using 555 ic drv10866 driver ic is given below.
Keeping that in mind a bldc motor is a type of synchronous motor in the sense that the magnetic field generated by the stator and the rotor revolve at the same frequency.
But at some time i try push the motor shaft the motor rotates for a few seconds and then stop rotate and make noise again.

Construction of bldc motor.
So the spinning is yield of changes in current direction of coil.
It means that there is no direct connection brush between rotating spindle and other fixed parts like as coil.
A brushless dc motor or bldc is a type of motor without any brush.
Run a cdrom brushless motor with arduino.
There were two important problems in that project as follow low speed and torque of the motor due to minimal signaling ic overhea.
It gives a beep.
But it didnt completed the whole 12 turns.
In the last bldc project run a cdrom brushless motor with arduino i ve used a l293 to drive a brushless dc motor.
Arduino cdrom bldc motor driver enhanced performance.
