Posted on May 12, 2018 at 19:44 We used BT139X-600E triac. Opto triac MOC3052 used for triac's control. Load is 230V, 50 Hz LED lamp, current is 30 mA. Current is not very nonlinear - it is short 'pulses' in the maximum of voltage 230 V. The triac...
Posted on February 07, 2018 at 17:51Hello, I am new to STM32 and to ST products in general. I am developing a BLDC motor controller. Until now we've been working with other MCU development platform but we want to research other solutions as well. ST...
Posted on May 17, 2018 at 15:24I would need advice on how to make a stepper motor drive with a supply voltage of 120Vdc and a current of 6 nominal Amps.It seems to me there are only 2 ways, even if I do not know if they are feasible, they are:1) Use...
Posted on March 21, 2018 at 20:50 I found only more requests of the same in this forum and no answers. Using Hall sensors for motor control is most typical today. 6-step BLDC code example provided in X-CUBE-SPN8 is sensorless only. There are driver...
Posted on May 10, 2018 at 18:18Hy,I'm using X-NUCLEO-IHM03A1 'High power stepper motor driver expansion board based on powerSTEP01 for STM32 Nucleo'I want to know if when there is a problem of undervoltage or overcurrent during a GoTo command the dr...
Posted on December 02, 2017 at 12:18I having traouble with the H-Bridge 'VNH5180A'. I tried to find the problem now for some days, but I wasn't able to find it. The H-Bridge haven't the right output voltage. At the Pins of the Bridge are these volta...
Posted on May 09, 2018 at 12:39Viper26 - Output Voltage drop also on light load Hi everyone,I've used the eDesigneSuite tool to draw a buck converter. Specs are simple: Input Voltage: 185~265 Volts, Output Voltage: 4.5 Volts; Output current: 0.4 Amp...
Posted on May 09, 2018 at 12:14hello guys, I bought STPM34TR from one of my supplier, the this part didn't work on the board. When it was tested, the value was not in the normal range, please refer to the attached file I don;t know what is problem. ...
