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

Closed-loop stepper motors may be the best choice for tasks typically done by servos because traditional steppers couldn’t handle them.

Most interestingly, it uses closed-loop feedback and DC motors instead of steppers, and it uses a fairly beefy 32-bit ARM processor instead of the glorified Arduino Uno that’s running many ...

Like other PCB motors it produces very little torque, roughly 2% of a typical NEMA17 stepper motor. Even so, the engineering behind this project remains impressive.

Stepper motors have several attributes. They generate incremental motion and generally run open-loop, and this eliminates the cost and complexity of an encoder or resolver.

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.
