This is in part because open loop operation can run at faster speeds than closed loop but also because the controller does not need to process the signal inputs from the hall sensors. what the mosfet use? Hi Maciek G! i see some escs using S8050 instead of IR2104. hey Simple projects, Implementing sensorless FOC requires taking signal measurements and performing math calculations. Typical examples include the speed and torque range you are looking for. 5) Eventually exit the for loop and increment to the next step of the commutation sequence. When i press reset on Arduino the motor rotates foe a few seconds and then it gets stuck and makes screeching noise. Allegro supports designs that are in progress or designs for those who cannot switch to the -A version. An understanding of this can quickly rule out several options, whilst quickly pointing towards other solutions. I used a 0.8A 90volt power suply. The biggest capacitor in the video is for 12V source. the motor area and it is felt that there is the potential for a back-EMF voltage spike to be fed back along that copper track and damage the IR2104 chip or even the Arduino board itself. As a starting point, source code for the firmware flashed on the BLDC shield is available as Keil uVision project files. But if i use a power supply higher than 12v, what resistor should i use for the virtual point and voltage divider? A broad portfolio with high power density at any voltage i did this testing only on the big BLDC drum and have not tried another motor. Sensorless BLDC motor doesnt have any sensor to detect its rotor position, its commutation is based on the BEMF (Back Electromotive Force) produced in the stator windings. 3.- Increase the voltage to where you propose Simple projects. The basic difference being the BLDC motor requires the commutation to be performed by electronic means rather than mechanical brushes.
