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 ...

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 ...

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 ...

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 ...

An interesting trend in industrial motion control has been the replacement of self-contained encoders (rotation sensors with their own housing, bearings and shaft) with modular or “kit” encoders.

As previously mentioned, the feedback sensors include position sensors to track the rotor’s location, current sensors to measure the motor phase currents, voltage sensors to monitor the DC bus voltage ...

The new SC Series from Nanotec Electronic is an out-of-the-box combination of a stepper motor with an optical encoder. The first two motors are available in sizes 60 mm (NEMA 24) and 41 mm NEMA 17.

Encoders are fantastically useful devices for human-machine interfacing. The issue for the makers, teachers, students, and engineers trying to use them is that many have less-than-ideal output signals ...

The topic of motors and motor control techniques is wide and varied. Part one of this two-part article will cover the principles of alternating-current (AC) motor operation and control. Part two will ...
