Controller for Universal Motor in DC mode

Hello,I want to drive a Universal Motor in DC mode. I am looking for a suitable controller. Can andybody help me?

Overcurrent fault always set without PWM enabled.

I have a 446re nucleo and IHM07M1. I am just trying to get my 6 step BLDC with Hall sensors to work. My overcurrent PIN 'PA6' is set all the time. As soon as i turn on 12 V DC to IHM and USB to nucleo , i read the PIN as HIGH. I have measured the vol...

This is a question about the signal name of VIPer22A.

I am repairing the power supply of AC-DC5V. According to the VIPer22A data sheet, pins 5-8 are "DRAIN" It was confirmed that the purchased VIPer22A has the same pin number 5-8. However, the VIPer22A (4PY138) used for the AC-DC5V power circuit purchas...

VN340SP-E DIAFG signal

Hi,I'm using the VN340SP-E on a board to drive 4 output inductive loads from a 24V voltageIn one condition I connected solonoids (which are actually inductors) to the outputs. I activated the 24V on the output stage and power was applied to the induc...

Should a inductor be added between Cin and the drain of MOS in the applicaion of Liner Voltage Regulator in L9779

 I've got a problem about the engine management IC——L9779. I would really appreciate that if you could help.Here is the thing：  A Liner Voltage Regulator has been built on this chip, which could transit the voltage from 12V to 5V and 3.3V.And this Re...

STEVAL SPIN3201 Hall Effect RPM Stability 3000RPM +/- 1.5RPM

Dear CommunityI have developed a BLDC motor drive with a senorles BACKEMF control using a DRV10983 IC.It uses sensor less control no halls used. If I look at the motors hall effects that are not used on the DRV10983 Chip My issue is that the speed is...

ST IHM08M1 Shottky Diode for Encoder and Hall

Hi,I need the circuitry on the IHM08M1 board for the encoder and hall sensors two times.I would like to ask, is there an alternative diode for the BATFILM30K, which is not built for SMD, instead built for THT.In the data sheet "Diodes and rectifiers"...

HVLED001A and TSM103 or TSM1012 for dimming application.

I'm developing a led driver dimmerable, and i'd like to understand how I could connect a dimmer to TSM103 or TSM1012. thanks for the help
