having trouble getting the motor to run at a consistent speed

I am working on a project that involves controlling a DC motor using a microcontroller. I am having trouble getting the motor to run at a consistent speed and it keeps stalling. I have tried adjusting the PWM signal and playing with the circuit but n...

Resolved! X-NUCLEO-IHM07M1 can not drive l6230 through input PWM to obtain normal and stable voltage due to overcurrent protection

Hello,I have a X-NUCLEO-IHM07M1 suite. When I used this hardware and the FOC algorithm(PWM frequency is 8kHz) to drive a BLDC motor. Then I found that the overcurrent protection was always triggered, but I didn't know why it was triggered and how to ...

Does the STMPWD13F60 require that it be run with a PWM signal (AC) or can it be run DC? If needs inputs to change what are the frequency and pulse width limits both low and high ?

* LED2001 Can I use "VINA" to use it as enable ? "PWM commercial module" is used. When this board is powered on, high is output for 500msec and then pulse is output. So when the power is turned on, I want to keep the VINA pin low for 500msec.

What is the PWM Ramp Voltage of SG3525

I need to calculate the analog compensator values so I need to know pwm ramp voltage of sg3525 but I cant find on datasheet, can somebody help me about it?

Why and how is PWM implemented in Field Oriented Control (FOC) ?

Hi everyone, I am trying to understand and implement FOC algorithm in MATLAB for a PMSM. I understand we are converting the 3 phase stator currents into 2 time-invariant stator currents: (direct and quadrature currents or Id and Iq, respectively). Bu...

Signal sniffer

Hi everyone.I have a position encoder connected to a motor drive. The encoder transmit every 0.1ms a 73-bit data package using a protocol called EnDat 2.2 to the drive. The clock frequency is set to 5MHz, meaning one bit is 0.2 microsecond. Now I wan...

I am looking for Reference code to generate 180 Deg phase shift PWMs for two phase interleaved synchronous buck converter. I am using STM8L152C8. If anyone can help on this. Thanks Manish

Use the L6563s to design a dc power

Posted on June 28, 2018 at 10:24Hi?I use the L6563S to design a 200W DC power.I just wanted to know how the L6563s to start working .I don't know the effect of diode D0 betweeninductanceT1 and capacitorC0.What it needs to work normally form the sta...

Using L6599 STBY pin for power output control through PWM

Posted on June 26, 2017 at 14:37Hi, I'm trying to design an LED driver using L6599 and L6533 (boost then LLC) stages, I'd like to know if I can use a 300Hz PWM on the STBY pin of 6599 to drive the output in a PWM dimming control? The datasheet doesn...
