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 ...

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 ...

Magnetic-free dual-coil technology can create a high-resolution, precise, and reliable solution for motor position sensors used in robotics, industrial, and medical devices. The need for accuracy and ...

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 ...

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 ...

Rotary encoders are indispensable tools for providing position feedback in many motion-control and automation processes. Lifts, overhead monorails, automated storage and retrieval systems, and cranes ...

A quadrature encoder uses two output channels offset in phase to detect both direction and position with greater precision.

A while back we featured a magnetic rotary encoder that [LongHairedHacker] designed. The heart of the system is an AS5043 magnetic rotary sensor which runs from $6.5-$11 and has a 10 bits precision.

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 ...
