FOC PMSM motor controller : measure phase current with mosfets Drain/Source voltage

Hello, I developed by the past some FOC controllers with the STM32 PMSM FOC Firmware Library v3.0.For the phase current measurement, I used isolated current sensor (section 4.3 of STM32 PMSM MC Library v3.0 User manual.pdf).For a new design, I thinki...

I think the STM group not at all replying the people questions. May be they are not having interest to their followers.

I want to drive the BLDC motor and I have STM32F411 Nucleo-64 and L6230 BLDC motor expension board. I wanted to interface the motor and integrate the QEI encoder feedback with the same kit

Could anyone please share coding or tell me now I can interface the QEI signals with STM32F411 Nucleo board.

Battery life estimation calculator

Hello,Does anyone know the formula used to calculate the life of the battery?She uses self-discharge in the calculation.Thank you

I have a question about STEVAL-IHM023V3. I would like to run the 24VDC BLDC motor and 300VDC BLDC motor by using STEVAL-IHM023V3. Could you give me kind and detail explanation about range of the motor and the configuration?

In my 3 phase inverter design i need to increase the current rating. So i decided to parallel the mosfets to attain high current rating. I came across the" paralleling mosfets pfc " and even more datasheet. Is this circuit correct

Using a Viper12 to run leds over 50-1000V range

Hi im struggling with a circuit im designing, im trying to run 3x 24V indicators using a Viper12 circuit. Ive set the circuit up as below:The idea is that the pre circuit introduces the Zeners at 650V, offsetting the input to the Viper circuit by 400...
