Hi everyone. I'm working ​on to drive 3 wheel omniwheel system for our project. I'm using parallel connection to have larger current. I realize that when i connect all the input and enable pins to ground (logic 0), all the leds connected to the outpu...

PWD13F60 Interference between MOSFET pairs in full-bridge frequency converter

 Hello to everyone. I'm making a 200W frequency converter for motor driving with APFC (~85...265 AC input) at my own 2-layers PCB and have some questions about influence from one half-bridge to another half-bridge inside the IC. Parts are driven in u...

How to control Speed of Eval6229pd

Hi,I have Eval6229pd and I am having trouble in controlling of speed. It was controlling via arduino pwm. when vref is adjust there is no effect in terms of speed. So I was adjusting it by fwd/rev but the certain speed that I'd expect was not met. Is...

Hello,I'm trying to export the PSPICE model from eDesign Suite so I can embed it with our design in OrCAD. Is there a way to download the model from eDesign?

L4984D

Well, I have posted a question in the eDesignSuite Q&A, but it seems to be the wrong place for it. Lets try here.I am looking for information about to feed the L4984D through self-supply. Does this controller works with self-supply or it is necessary...

How to configure POWERSTEP01 to limit Motor Phase Current

Hey,i bought <nucleo-F401RE> and <x-NUCLEO-IHM03A1> boards in order to drive the NEMA 17 "QSH-4218-51" bipolar step motor. this one can be supply under 24V with 1A phase current. Using "BASETech-305" Volage Generator, i supplie the <x-NUCLEO-IHM03A1>...

[STSPIN32F0] 6-step control: Set phase out in float mode

Hello,I am using the STEVAL-SPIN3201 board to control a BLDC motor.I want to implement a position controller, so I need to hold tight the position of the rotor at a given position (1 phase to Gnd, 1 phase to pulsed Vm, and 1 floating phase).The probl...
