In direct drive motors, the encoder’s signal quality plays a critical role in the amount of electrical current noise, which affects the motor’s dynamic performance and possible power dissipation.

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… ...

Heidenhain is proud to announce the addition of its new slim-design ECI 1118 rotary encoder to its expansive product line.

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.

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 ...

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 ...

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 ...

The new SC Series from Nanotec Electronic is an out-of-the-box combination of a stepper motor with an optical encoder.

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 ...
