In motion control applications, you frequently hear all sorts of loops -- open, closed, current, torque, speed, voltage, and so on. Here, we define and explain these terms.

Open-loop vector (OLV) control is used for greater and more dynamic motor control. It independently controls motor speed and torque, much like DC motors are controlled.

Precise setting of a speed profile is done by the built-in non-volatile memory (NVM) and TC78B027FTG therefore eliminates the need for an external MCU for a closed loop speed control.

It is estimated that 40% to 60% of the ac motor applications would benefit from some form of closed-loop, smart speed control. Closed-loop control allows single-phase ac motors to close the gap in ...

The topic of motors and motor control techniques is wide and varied. Part one of this two-part article will cover the principles of alternating-current (AC) motor operation and control. Part two will ...

Almost two years ago, a research team showed that it was possible to get fine motor control from cheap, brushless DC motors. Normally this is not feasible because the motors are built-in such a way… ...

How about an analogue motor speed control? These are things that I have never given much though to – I knew they compensated for something in a sort-of open-loop way, but not what. Anyway, after ...
