Hello,I am trying to develop my own sensorless motor control using the STEVAL-ESC001V1 Board. The motor used is a 6 poles BLDC motor. I have successfully been able to run the motor in open loop and it’s running well.In order to have feedback and esti...
Hi, I am a bit confused about PWM motor driving. Is Vref the same value as Vavg of PWM? I tried to calculate the value of PWM current control but there have the result is not the same current value as I measured from a test, here are the parameters;R...
I would like to know the working principle of the charger bump for MH98, as well as the working principles of CPOUT, CP1, and CP2. Why can the voltage of the bootstrap capacitor reach 11.3V when VDH = 6V? In other words, why can the voltage of CP rea...
HelloCould someone please help me with information on how to define the values of the capacitors and resistors seen in the figure of the typical circuit? Thanks
We are using the PowerSTEP01 driver in Current mode to drive the NEMA23 stepper motor.Supply voltage: 24V DC, Motor current 0.9A set in driver (motor max current is 2.1A)RPM Range 0 -1800 rpm; (0 - 6500 steps/sec)Acceleration / deceleration = 10000 ...
I hope this is an appropriate group. I don't see L6235Q anywhere. Is ST going to make any more Eval6235 boards? There doesn't seem to be any on earth. Choosing another controller is not an option. Mike
I am buying a EVSPIN32G4 evaluation board. What are the things I should test or check on the new board for any faults or damages
I found an aplication (ST Design Tip - DT0001), that suggests a way of controlling motor speed, using a PWM signal on the DIR input. Works fine for speed. Note: we are not using a micro as shown in the DT90001. We are using our design. And using P...
Hi,This value is not defined in the datasheet ( DS14341 - Rev 2 )Figure is attachedAny ideas?Thanks,Tim
I am running a STEVAL-ILL035V1 board using software downloaded from your site.Downloaded software is LED_DRIVER_GUI7708_1.0.1_130722.exe.Then I connected an additional board STEVAL-ILL035V2 and changed SW7 on ...V1.But now I am not able to control th...
