BLDC motor loud grinding noise on open loop ramp with STSW-ESC002V1 running on STEVAL-ESC002V1 board (STSPIN32F0A)

On ramp to 1000 RPM, intense rhythmic motor grinding noise (attached video). At 1000 RPM after hand over to PID, motor runs smoothly with no noise.Attached file with motor parameters header file and precompiled settingsThank you for any suggestions.

ST7580 - DC Application

I want to use the ST7850 in a DC application, where there is no "mains voltage" but 12...24V DC Supply. I've taken a look at other schematics that use powerline modems, and i think it would only be necessary to remove the insulation transformer plus ...

STLA02, In the datasheet I have seen the resistor value is calculated as per for feedback voltage.How I can control the booster voltage.What is the Voltage at the Vout pin.

Can i use RCM flow in "regular_conversion_manager.c" to do ADC Injected channel conversion?

Dear I want to get 3-phase current, but due to 3 phase current belong to ADC injected channelAfter checking the "RCM_ExecRegularConv" function, i find that it will call LL_ADC_REG_StartConversion to do adc conversion. I'm wonder whether i can use th...

Time over of L6924D Charger

Hi all,I fixed 3 hours fot the maximum charge time.The question is : when Tmaxch =0, the condition will be IND FAULT so the circuit restart the charge or user who will do that ?Thanks and best regardKhalil

Where to get the ST PLM Dongle Programmer and ST PLM Frame Manager GUI software?

We have a few STEVAL-IHP002V2 modules and a STEVAL-IHP005V1 module to setup an experimental smartplug application using PLC. We are faced with two major issues and spent a lot of time trying to figure out and hope you can help us with giving us some ...

How to setup STEVAL-002V2 using GUI software.

Do you have a Windows 10 version of STEVAL-IHP005V1_Setup?

We have laptops running Windows 8 and Windows 10 and on both we installed this software STEVAL-IHP005V1_Setup.exe and the software crashes every time. We set the compatibility mode to Windows 7 and still the same issue. Unable to use this software to...

STM6600 voltage divider on VCC for high voltage applications

Hi, I'm evaluating the STM6600 on/off controller. My application has a 2-series LiPo battery with a voltage range of 6 to 8.4V, so I need to put a voltage divider before VCC as described in AN3271. The calculations for the divider provided in that do...
