[Frank Herrmann] had an interesting idea to turn a geared DC motor into a servo motor assembly, but with a stepper motor-like interface. By stacking some small PCBs behind the motor body, it was ...

The new magnetic encoders from Posital provide absolute position feedback They are available with multi-turn measurement ranges which can be useful when a motor is connected to a screw shaft, cable ...

They do this with greater efficiency and less motor heating because motor phase currents are regulated up and down according to need. Performance of the closed-loop steppers are similar to servo ...

An interesting trend in industrial motion control has been the replacement of self-contained encoders (rotation sensors with their own housing, bearings and shaft) with modular or “kit” encoders.

POSITAL is expanding its line of kit encoder solutions for motion control applications to satisfy a wider range of needs faced by machine builders, system integrators and motor manufacturers. Kit ...

Oriental Motor of Japan is offering stepper motors with battery-free multi-turn absolute position encoding that can ride through power-loss. Oriental Motor of Japan is offering stepper motors with ...

Robotic designs that operate autonomously or alongside human workers offer convenience, efficiency and accuracy, greatly benefiting the manufacturing and industrial sectors. Here, monitoring motor ...

When you think about highly-precise actuators, stepper motors probably aren’t the first device that comes to mind. However, as [Diffraction Limited]’s sub-micron capable micro-manipulator shows, they ...

Rotary encoders convert rotary movement or angular position into analogue or digital signals for use in measurement or control systems. They can be classified in a number of ways, primarily by the ...

Encoders are a vital component in many applications that require motion control and feedback information. Whether a system’s requirement is speed, direction, or distance, an encoder produces control ...

The International Electrotechnical Commission (IEC) defines a servo device as “an adjustable-speed AC power drive system that includes an AC motor integrated by feedback, a converter, and control, ...
