The closed-loop design of the Nema 8 stepper motor with encoder allows it to provide precise and accurate motion control, with minimal risk of missed steps or positioning errors. The encoder provides feedback to the control system, allowing it to correct any errors in real-time and ensure that the motor is always in the correct position.

Features:

Bipolar or unipolar versions available
Hybrid stepper construction
Available in single or double shaft versions
CE and RoHS approved
Customizations on request
