sinusoidal PWM control for PMSM motor

Hi friends,   I am working in electric vechicle controller segment. Already, I have done my bldc controller using six step ( trapezoidal ) control method. I was completed my project using STM32f103c8t6 controller.  I need to control the PMSM motor us...

Is the stps5l60sfy footprint PSMC (TO-277A) too big?

We got this picture from our PCB manufacture. They claim there is "too much footprint" for this component and it causes sliding of the part. The footprint is made with reference to page 6 of this document. https://www.st.com/resource/en/datasheet/stp...

Nucleo Expansion Board Compatibility

Anyone know if the X-NUCLEO-IHM07M1 motor driver expansion board is compatible with the NUCLEO-F746ZG?

Signal sniffer

Hi everyone.I have a position encoder connected to a motor drive. The encoder transmit every 0.1ms a 73-bit data package using a protocol called EnDat 2.2 to the drive. The clock frequency is set to 5MHz, meaning one bit is 0.2 microsecond. Now I wan...

Battery Analyzer

Dear sir,We want to design a Battery analyzer for automotive purpose. The range of battery voltage can be 9V to 36V. Can you please suggest me an appropriate part number or reference design.Regards,Manoj HiwarkarEmbedded Engineer,9916707384 / 8087764...

We have designed in several LD56100 3.3 V LDOs. The datasheet specifies that the ESR of the output cap must be 3 to 300 mOhms. Over what frequency range is that required?

How to choose a proper MCU for DC fast charger ?

The interface between the Power Control Unit and the Control Unit is via CAN bus and the interface between the Communication Board and the Control Unit is via MQTT.Thank you for your time!

BLDC motor speed control using PID

HI all,I am trying to implement PID algorithm to control speed of bldc motor. For that the RPM of the motor is measured using Hall sensor. Now I have to write the code for pid can anybody tell the logic or example!I have studied about the PID control...

L5973D - 100% Duty Cycle Not Working

Hi,I have an L5973D set up for 28.5V output from 30V ish input for 2A current. The design requires the regulator to go to 100% duty cycle when the input voltage drops. At low currents (up to 1.5A) the device behaves correctly and smoothly transition...
