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… ...

Brushless DC (BLDC) motors are standard fare in low-precision, speedy RC applications. The control schemes needed to run them slowly or precisely go deep into motor theory and might put these motor… ...

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 ...
