Timing the Commutation Channels of an Optical Encoder to a Brushless Motor

Alignment of optical encoder commutation signals to a Brushless DC (BLDC) motor could be thought of as being comparable to timing the distributor on a car engine. The distributor tells the spark plugs ...

Simplifying BLDC Commutation and Feedback System

In a Brushless DC (BLDC) motor system, an electronic mechanism is required to commutate the system. Unlike a Brush DC motor system, the permanent magnet is located at the rotor and the windings are ...

Optical encoders encourage efficiency

Get the most out of brushless dc motors by specifying optical encoders. They measure finer movements than hall sensors, because their operation doesn't rely on motor phases. Brushless dc (BLDC) motors ...
