The DECS 50/5 speed controller drives brushless DC (BLDC) motors without Hall sensors. Measuring about the size of a business card, the unit accepts an input-voltage range from 10V to 50V and ...

One way to commutate BLDC motors is with the “six-step” or “trapezoidal” technique, which relies on Hall-effect sensors ... three blocks in the system diagram that require position ...

The integrated Hall sensor used to detect the rotational position ... making this device in BLDC motors superior to existing brush motor solutions. A micro power sleep mode can be initiated ...
