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 ...

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 ...

(Nanowerk News) Global precision motion control and nanopositioning industry leader PI introduces a new high dynamics linear motor stage family, the V-574 - a new series of linear positioning stages ...

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 ...

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 ...

Why are there so many different angle encoders on the market? Why do they use different scanning and measuring methods? And which one should a designer choose? To answer those questions, engineers at ...

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 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 ...

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 ...

There are a lot of cheap Chinese CNC machines out there with okay mechanics and terrible electronics. The bearings aren’t complete crap, but the spindle of these CNC machines is a standalone PWM ...
