<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-B is a versatile NEMA 17 (42mm) closed-loop stepper motor system. As the "M" (Medium) version, it features a body length of approximately 40mm, providing substantial holding torque (0.44 N·m) while remaining compact enough for space-constrained applications. This model is equipped with the advanced "B" Type (20,000 PPR) high-resolution optical encoder, making it an excellent choice for general-purpose precision stages, 3D printers, and medical devices that require smoother motion and higher accuracy than standard models.

Key Features

• Optimal Size-to-Performance Ratio: The Medium stack design delivers 0.44 N·m of torque in a compact 40mm body, suitable for the majority of NEMA 17 applications.

• Ultra-High Resolution: Features a 20,000 PPR (Pulse Per Revolution) encoder, offering double the resolution of standard "A" type models (0.018° per step) for extremely fine positioning.

• Closed Loop System: The embedded controller continuously monitors the motor position to ensure no loss of synchronization (step-out) even under sudden load changes.

• No Hunting: Maintains a completely stable stop position without oscillation, ensuring reliability for vision inspection and optical alignment tasks.

• Smooth Operation: The high-resolution feedback combined with vector control minimizes vibration and noise, even at low speeds.
