Commercial shaft encoders use magnets and Hall-effect sensors, or optical sensors and encoder discs. But these can be quite expensive, so [Hello1024] hacked together an alternative in an afternoon.

Titanio series stepper drives from Ever Motion Solutions include three new drives available with two open-loop (no encoder ...

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.

If you have a motor and you’d like to know where the shaft position is, you are likely to turn to an optical encoder scheme. However, as [lingib] points out, you can also use a magnet and a ...

Absolute rotary encoders work on motors up to 8,000rpm Same Sky has created an absolute encoder family for motor shafts from 9 to 15.875mm (5/8inch).

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.

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 ...

Encoder specialist POSITAL has expanded its line of kit-style encoders for feedback for servo and stepper motors with new models that utilize the same mounting form factor as incremental kit encoders ...

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 ...
