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 ...

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 ...

Is your motor spinning at the intended rate? Closed-loop motor control systems continue to answer this question, as there tends to be a closed-loop system implemented wherever a motor spins. Whether ...

The electric motor is the fundamental building block of almost all robotic projects but, without some form of feedback, it lacks the precise positional control required for the task. Small servos from ...

The SKM 36 SinCos Motor Feedback System is a multi-turn rotary encoder that tracks absolute position over 4,096 turns. The SKM 36 features a minimum number of components to allow miniature and ...

A DSP design approach, including hardware and software implementation for a quasi-absolute encoder. LEE WEI YAN, Applications Engineer, Avago Technologies, San Jose, Calif. A high-accuracy 20-bit ...

To improve the speed and control of rotary actuators used in laser scanning and other optical systems, engineers at Pangolin Laser Systems, Orlando, Fla., decided to take matters into their own hands ...

The Hardinge DD100 is capable of spindle speeds up to 4,200 deg/sec and up to 600 rpm continuous rotation — over 10x faster than a gear-driven indexer, the developer indicates. The standard DD100 ...

How do you make things move? You add in a motor that converts electrical energy into motion. That’s a simple idea, but how do you know where the motor is? That’s where the servo motor comes in. By ...

The U-628 rotary stage is equipped with an ultrasonic ceramic motor for fast response and high speed. On a very small footprint of only 2x2 inches, it provides high rotational velocity up to 1080 ...
