Posted on June 18, 2012 at 13:30Hi I am trying to setup the ST FOC library with a small BLDC-motor with hall sensors. I am using the evaluation board STEVAL-IFN003V1. I have configured all parameters of the system with the ST Motor Control Workbenc...
Posted on June 19, 2012 at 10:09We are starting a new project for a sensorless BLDC control.We select STM8S903K3 as MCU.Do anybody have a S/W source code can use? It's our first project which use STM8S,we haven't experience.We want to speedy the pro...
Posted on June 07, 2012 at 15:05Hello all.I would like to receive some suggestions of ICs / considerations about this design.The picture below states how this power supply should work.http://e2e.ti.com/cfs-file.ashx/__key/communityserver-discussions...
Posted on March 22, 2012 at 02:32Hi I have several different motors that I would like to drive (one at a time) using the same hardware and firmware based on the STM32 FOC PMSM libraries. The motor selection is indicated to the processor with a DIP s...
Posted on May 16, 2012 at 06:08I have an application where i need to use Viper25H in non-isolated mode.For reference generation I am using TL431. But the problem is that when TL431 is used for non-isolated configuration , power supply is getting int...
Posted on April 28, 2012 at 08:56Hi all, I got a 200 Watt Resonant SMPS board based on L6599 (STEVAL-ISA018V1) and wanted to simulate it with the eDesignSuite but I couldn't find a L6599 design. It seems that there are no eDesigns for the L6599 ava...
Posted on April 11, 2012 at 16:34Hello, I'm a bit confused about the timer usage for the Hall sensors on the STM3210B-EVAL board. The encoder signals (which are used for the hall signals too) are placed on the GPIOs PA0, PA1 and PA2 and timer TIM2 i...
Posted on April 10, 2012 at 02:44The new eDesignstudio does not support the VIPER53E. Original design was done by software supported by ST, but can not find it on the web. Can you send me or point me to where I can get a copy?
Posted on March 19, 2012 at 10:50Hi everybody On my simple Cw, Ccw control, for low power brushed d.c. motors, realized around L6207, i need to adjust the motor's speed. Is it a good idea to Pulse Width modulate the enable input (EA) instead using ...
Posted on March 20, 2012 at 18:09Hi! I have some questions about L6470 decoupling and voltage tolerance.1. If I use an external 3.3v to drive both Vreg and Vdd (internal reg disabled), do I still need a 40uf Vreg cap or I can use just one 10uf?2. Ca...
