<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-STEP-BT-42L is the "Large" stack version of the NEMA 17 (42mm) Ezi-STEP BT series. With a body length of 48mm, it delivers a strong holding torque of 0.5 N·m, making it a powerful option for applications that require more force than standard short motors but still need to fit within the NEMA 17 footprint. This unit features an integrated high-performance drive built directly into the rear of the motor, significantly reducing wiring complexity and saving valuable space in control panels.

<Key Features>

High Torque Density: The Large stack design produces 0.5 N·m of holding torque, offering a significant upgrade in power over the S and M models for driving heavier loads.

Integrated Drive System: Combines the stepper motor and drive into a single "All-in-One" unit, eliminating the need for a separate driver and simplifying machine cabling.

High Precision: Features a high-performance 32-bit MCU that supports resolutions from 1.8° down to 0.0072° (up to 50,000 pulses/rev), adjustable via software.

Software Damping: Equipped with proprietary vibration suppression technology that ensures smooth operation at both low and high speeds, reducing the need for mechanical dampers.

Status Monitoring: Includes Run/Stop output signals and LED indicators (Power/Alarm) to provide real-time operating status to the host controller.
