[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 ...

It uses another motor as the encoder, taking advantage of the minute changes in inductance as the magnet passes each of its coils. It’s a technique that works better with cheaper motors ...

The new SilverPak 23DE, an integrated Nema 23, high torque, 1.8 degree bipolar step motor, microstepping driver and encoder is designed to reduce overall design time and system cost for a wide array ...

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 ...

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 ...

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 ...

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 ...

Compact encoder's integrated third channel and high resolution enable a smaller motor encoding system than ever before — to cut design costs and save PCB board space for industrial automation ...

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 ...
