How does a stepper motor turn into an encoder? Well, that’s the MacGyver part. We are not big fans of the physical circuit diagrams, but it looks like [Tech Build] borrowed (with credit ...

To answer those questions, engineers at Heidenhain set up a torque motor commanded by a CNC controller hooked up to four different angle encoders to see how they differ. The four absolute angle ...

For integrated motor feedback, the measurement components of an encoder are attached to a motor’s housing, with rotary motions measured directly from the drive shaft. The technologies used in ...

Rotary encoding is a common mechanism for the delivery of accurate speed, acceleration, and position of the motor rotor. Rotary encoders are commonly deployed in the closed-loop rotor systems used in ...

[Andriyf1] has a slightly different trick. He shows how to use a stepper motor as an encoder. You can see a video of the setup below. It makes sense. If the coils in the stepper can move the shaft ...

The TSM14POE StepSERVO from Applied Motion includes a motor, encoder, drive, and controller combined in a single integrated motor package. The TSM14POE StepSERVO from Applied Motion includes a motor, ...

This Design Idea combines a simple ISA-bus-resident interface circuit; a garden-variety PC; a high-resolution optical shaft encoder; and a PWM-controlled, 0.05-hp, brushed, permanent-magnet dc motor ...
