Brushless motors are ubiquitous in RC applications and robotics, but are usually driven with low-cost motor controllers that have to be controlled with RC-style PWM signals and don’t allow fo… ...

You can salvage some nice motors out of optical drives but they can be tricky to control. That’s because brushless DC motors require carefully timed signals used in a process called Electronic ...

Because students are using it, it needs to be short-circuit-proof – no possibility that a mix-up in control signals can cause the drive to short out the rails (see DANGER, right). BTW, don’t use these ...

However, cheap mosfet-based mains motor controllers seem to be a lot less robust than SCR types – partly, I suspect, through the natural robustness of thyristors, and partly due to under-specifying ...

A family of NovalithIC components from Infineon integrates the control chip and MOSFETs into a single component. Rutronik expects this to bring a new level of performance to integrated and protected ...
