Hello, everyone.I am currently studying FOC for BLDCM.A motor with magnetic encoder AS5048A was used.The PWM output of the magnetic encoder works normally, but I failed to get the SPI interface to work normally.If you have ever used this magnetic enc...
Hello I am working on a 48V BLDC drive unit and I would like to implement the safety feature "Safe Limitd Speed" according SIL2/3 and PLc/d.In the Motor Control Reference Guide from ST there is "Safety ready: SIL, Class B" as one of the key features ...
Hello friends, i want to read ADC value for particular time. That is, to read the analog value during the middle time of every pwm signal. Triggering ADC via timer.I had generated pwm signal with 50% duty cycle in center align mode so that we could e...
Hi All,Using a 36V motor that is rated for peak of 20.5A. I always get an overcurrent fault on startup even though my current output is only 0.8A. Any guidance would be appreciated, and I am happy to provide more details if needed.Thanks,-Nick
Hello,I would like to build a circuit to drive a three phase BLDC motor and the board EVSPIN32F0251S1 seems to be a choice, but i can't find the software easily. Does anyone know a three phase BLDC firmware project for this board? My build tool is Ke...
Hello. I am using Steval - spin3204 and motor jk86bls71-03-x001. I am building a project for Keil in ST Motor control 5.4.3. But I can’t start the engine with or without Hall sensors. I tried to make various configurations of PID controllers, PWM par...
Hi, I read in the Data Brief of the STEVAL-SPIN3201 module that it can ouput up to 15 Arms of current but I can't find in the schematic why that it. The mosfet used on the board (STD140N6F7) seems capable of higher current output.We want to port the ...
I have a 5V line that I need to step down to 3.3V in order to power the MCU. I can use a switching regulator that I like (http://www.ti.com/product/LM3241) to provide 3.3V with a 6MHz ripple. If that ripple is not acceptable for either the Vdd or Vd...
