I was still not able to drive the motor into instability with the ‘IR’ control, wherever it was set, but will try operating the mill for a while to see of there is significant speed droop before the ...

Speed control of DC motors is devoid from drift whilst remaining dynamic. The DC motor speed can be controlled from 0 rpm up to 150,000 rpm. A completely configurable broad range of functions can ...

he knew that his invention was more efficient and reliable than Edison's direct current (DC) motor. However, AC motor speed control requires either varying the magnetic flux or changing the number of ...

I was planning to use the opto-coupler speed sensor as part of a motor speed control – making the motor into the VCO block in a phase-locked ... What I didn’t know was that the difference between ...

This time he’s using a motor controller that has four half H-bridges built into it. He hooks up the SN754410 to two motors, giving him speed and direction control for both based on the duty ...

Recently, I found an interesting fan motor module in a web shop and grabbed a couple of them for nothing. At the heart of the module is an eight-pin L9110 DC motor control chip from ASIC (www.asic.net ...

For motor applications, engineers have several options at their disposal. Typically, engineers can choose between direct-current ... greater control and higher efficiency. DC motors rely on ...
