It uses another motor as the encoder, taking advantage of the minute changes in inductance as the magnet passes each of its coils.

We always think it is interesting that a regular DC motor and a generator are about the same thing. Sure, each is optimized for its purpose, but inefficiencies aside, you can use electricity to rot… ...

Multiple quadrature encoder support: Mixed-signal FPGAs also offer another benefit for motor control – the capability of driving multiple motors (axles) simultaneously with single mixed-signal device.

Although integrated motor feedback is taking a growing share of the market for motion control systems, the future for standalone encoders continues to look bright.

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 ...

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 ...

Featuring easy installation and high performance in an optical ASIC caliper package, the KX21 series modular kit encoder uses set-screw mounting and provides an installation tool ...

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 ...

A standard reflective encoder module contains two digital output channels for direction sensing, but needs another module for indexing. Similarly, motion ...

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 ...
