Closed-loop stepper motors may be the best choice for tasks typically done by servos because traditional steppers couldn’t handle them. One of the more critical decisions engineers can make when ...

Typical closed-loop stepper-motor systems include a complicated controller or pulse generator. The controller senses the encoder or resolver feedback and does the comparing.

Building a 3D motor printed motor is one thing, but creating a completely custom servo motor with encoder requires some significant engineering. In the video after the break [365 Robots] takes us ...

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

Stepping up While open-loop SMLA systems are suitable for many applications, stepper motor users wanting real-time feedback on load position should consider adding encoders to their motors. Encoders ...

Aerotech’s XL4s linear amplifier for closed-loop servo control of voice coil and single-phase motors eliminates the nonlinearities common with PWM amplifiers. The unit provides deterministic behavior, ...
