Festo EMMT Series Hybrid Stepper Motor 48V, 0.63Nm Torque, 1.8 °, 57 mm Frame, 6.35 mm Shaft

This stepper motor provides precise open‑loop positioning and controlled rotary motion for automation and motion‑control systems. It operates from a 48 V DC supply and is designed for mounting in any orientation with protection rated to IP40 on the shaft and IP65 on the housing. The unit incorporates an absolute single‑turn magnetic encoder with BiSS‑C output to report rotor position and supports continuous operation within defined thermal limits.

• 1.8° step angle for accurate incremental movement
• 50 pole pairs delivering fine torque resolution
• 5.2 A nominal current enabling sustained torque output
• 0.26 Ω resistance per phase reducing voltage drop
• 1500 rpm maximum rotational speed for dynamic response

• Suitable for machine‑tool Axis positioning
• Ideal for pick‑and‑place automation systems
• Used with conveyor indexing mechanisms
• Can be used for rotary indexing tables
• Used for packaging‑line motion control

It includes an absolute single‑turn magnetic encoder with 16‑bit resolution and BiSS‑C Interface providing 65,536 position values per revolution.

The holding brake has 1.74 Nm torque, operates at 24 V, consumes 0.38 A, and permits one emergency stop per hour with a maximum friction energy per braking process of 6,000 J.

Ambient operation is -15 °C to 40 °C with derating up to 80 °C at -2%/°C

The shaft permits axial loads up to 15 N and radial loads up to 75 N.
