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.

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.

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 ...

JVL QuickStep closed-loop integrated stepper motors provide higher torque, faster acceleration, torque control, stall free operation and quieter movements than traditional step motor systems.

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.

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 ...
