New 12 And 24 Volt Brushless DC Speed Controls

The new type ABL-3906C low-voltage brushless DC controls provide variable speed control for BLDC (ECM) gearmotors and motors. The controls operate from a DC power supply or from a battery (12 VDC or 24 VDC, depending on the control model). They are ideal for portable or remote applications where connection to an AC line is not

What is a Sensorless Brushless DC Control? How does it work?

A sensorless brushless DC control consists of a power supply, a power stage, commutation logic, and startup logic. The key difference to an electronically commutated BLDC motor system is that the Hall sensor inputs are replaced by a system that measures generated voltage (BEMF = back EMF) and uses zero crossings to determine when to
