<Delivery Notice>

Fastec products are made to order, which may require an additional 2 to 4 weeks for production.

For this reason, cancellations or modifications are not possible once an order has been placed.

We will provide you with the confirmed production and delivery schedule after the order has been placed (manufacturing starts)

<Discription>

The EZI-SERVOII-CL-42M-A is the standard medium-sized model in the NEMA 17 (42mm) closed-loop stepper series. With a body length of approximately 40mm, it strikes an ideal balance between physical compactness and holding torque (approx. 0.44 N·m). It is equipped with the industry-standard "A" Type (10,000 PPR) optical encoder, making it the reliable, cost-effective choice for general precision applications such as 3D printing, medical pumps, and compact desktop automation.

Key Features

• Balanced Performance: The Medium stack design ("M") fits most NEMA 17 mounting footprints while providing sufficient torque for general loads, avoiding the bulk of the "L" version and the weakness of the "S" version.

• Standard High Resolution: Features a 10,000 PPR (Pulse Per Revolution) encoder, providing 40,000 steps per revolution (in 4x mode). This resolution is sufficient for the vast majority of positioning tasks.

• Closed Loop Control: Continuously monitors the motor position to prevent step-out (loss of synchronization), ensuring accurate motion even if the load fluctuates.

• No Tuning Required: Ready to run immediately without the complex gain tuning associated with servo motors.

• Stable Stop: Holds its position perfectly stable without hunting (oscillation), ideal for applications requiring steadiness while stopped.
