[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 ...

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 ...

The P760 series disc magnet motor from Portescap combines “Disc Magnet” technology and an optimized number of pole pairs to deliver 0.7-Nm torque and acceleration up to 5000 rpm. Disc Magnet ...

A new magnetic digital encoder featuring 14-bit resolution, differential outputs, and a speed range of up to 200-k e-RPM offers accurate and cost-effective position sensing for various robotic and ...

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.

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 ...

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 ...
