The electric motor is the fundamental building block of almost all robotic projects but, without some form of feedback, it lacks the precise positional control required for the task. Small servos from ...

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 ...

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 ...

Why are there so many different angle encoders on the market? Why do they use different scanning and measuring methods? And which one should a designer choose? To answer those questions, engineers at ...

Encoder tracking is a technique that monitors a reference motor with an encoder and controls a secondary motor. Encoder tracking is a technique that monitors a reference motor with an encoder and ...

Precisely tracking speed, acceleration, and position of a motor's rotor is an essential requirement for many motor control applications found in everyday equipment such as fax machines, elevators, and ...
