Initial torque problem in STSPIN32F0

I have tried to configure ​stspin32f0 as per the user guide instructions to get required starting torque from bldc ,it is not working properly.plese provide me the information what parameter i have to change to increase my starting torque.

Hi, I am looking for some examples how to implement DTC ( Direct Torque Control) on STM32. I would like to make my own code and I am looking for some practice information. Does anyone do something like this? Does Motor Control library support DTC?

Hello everyone, My question is about the VN750PS-E, a load driver. It's not clear in the datasheet... I would to know the maximun voltage could be apply on the CTRL_pin. Exemple : Control Alway on by CTRL_pin directly connected to the Vin pin, 36v...

Is it optimal that STBC08 Charger charges to 4.2v (100%) ?

HeyWe are using the STBC08 to charger a LiPo battery, the device charges to 4.2v which is the maximum voltage for battery, However I understand that charging to 100% is not optimal in terms of battery lifetime, and most sources recommend not charging...

Quality issue with STPS5L60U schottky diode?

I am using the STPS5L60U in a low voltage landscape driver design. Input is 9-15Vac. Circuit is a buck-boost. Driver chip is a TI LM3429, driving an external FET. Switching frequency is only 145kHz. COB load is 20V and 750mA. I use 4 of these d...

LM3424 waveforms? DemoBoard

Hi, i tried LM3424 demoboard and adjust to me purpose. All works perfect, but when i design my PCB and i put all the components, the waveform and the efficiency of the system changes, the waveform of the transistor on the drenator pin is differents b...

interleaved active clamp flyback converter

as per the figure we provides a dc voltage as a input to the interleaved active clamp flyback converter block, provide a PWM signal to the MOSFET which is in interleaved block for switching purpose. PWM signal is generated by the microcontroller whic...

I connect stm32 F207ZG to usb port and the chip overheats. LD5 also is on and LD3 does not blink. What goes wrong?

I tried to download a program for motor control. I think that this is the potential problem because I use wait(1) instead of wait(0.1)

STC3115 fuelgauge not working when RSTIO + SCL + SDA is ZERO.

Hi I am having a strange issue with STC3115.My system is designed in such a way that the main MCU and all circuitry is powered using a push button controller. On long press my MCU and all devices will be off but except the fuelgauge which is powered ...

How can I turn off a PWM signal and turn on a High (one) in the same pin?

I´m using a PWM signal and the complementary with TIM1(timer1). The Pwm´s complementary singal is going out from pin A7 then I want to turn off the pwm signal from that pin and turn on a HIGH value (one) in the exact same pin (A7). The thing is that ...
