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 ...

Position encoders are sensors that, when used in industrial settings, produce critical motor information such as speed and position. The encoder delivers data for display or data that may serve as ...

Encoders are widely used in the motion control and automation industry to monitor the position and speed of motors. This information can be used by the motion control electronics to detect if the ...

• The new mantra of position encoding is low-current drain. • Capacitive encoding is a way to realize low-power consumption without giving up resolution or accuracy, even at relatively low speeds.

Engineers using an incremental encoder for the first time often have a misunderstanding about what types of signals are provided by an encoder and how to interface an encoder to their application.

We always think it is interesting that a regular DC motor and a generator are about the same thing. Sure, each is optimized for its purpose, but inefficiencies aside, you can use electricity to rotate ...

Rotary encoders sense changes in the position of a rotating shaft, then generate signals that send speed, direction, and position information to a receiving device such as a counter, drive, or ...

To attain accurate positioning, a servo system requires a feedback signal to close its feedback loop. Instruments that typically supply the feedback signal include optical encoders, resolvers, and ...

In robotics, movements must be precise and well-controlled. As robots are asked to do more as industry becomes more familiar with the technology, there will be an increasing need for high accuracy ...

Last year, Automation World examined the differences between accuracy, resolution, and precision in the encoder world. And while understanding the differences among these terms is important to ...
