<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-56L-B is a powerful NEMA 23 (56mm) closed-loop stepper motor system. The "L" (Long) designation means this motor has a longer stack length compared to the Small (S) or Medium (M) versions, allowing it to deliver maximum holding torque within the 56mm frame size. It is equipped with a high-precision 20,000 pulse/revolution encoder ("B" Type), making it suitable for applications requiring both high torque and extremely fine positioning.

Key Features

• High Torque Output: The Long stack design maximizes magnetic flux, providing higher holding and running torque compared to standard 56mm motors.

• Ultra-High Resolution: Features the "B" type 20,000 PPR optical encoder, offering double the resolution of standard "A" type (10,000 PPR) models for precision motion.

• Closed Loop Reliability: Continuously monitors motor position to ensure no loss of synchronization (step-out), even under heavy loads or rapid acceleration.

• Vector Control: The drive uses software-based vector control to ensure smooth operation and reduced heat generation compared to open-loop systems.

• Fast Response: Ideal for short-pitch, fast-move applications due to its high torque-to-inertia ratio and instant settling time (no hunting).
