Festo EMMT-ST Series Stepper Motor, 48V Nominal Operating Voltage, 0.63Nm Holding Torque - EMMT-ST-57-L-RSB, Numeric Part Number: 8156183
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.
Features and Benefits:
• 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
• 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
Applications
• 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

What encoder capability is provided for closed‑loop feedback?
It includes an absolute single‑turn magnetic encoder with 16‑bit resolution and BiSS‑C Interface providing 65,536 position values per revolution.
How does the brake perform during emergency stops?
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.
What thermal and altitude operating limits apply?
Ambient operation is -15 °C to 40 °C with derating up to 80 °C at -2%/°C
installation up to 4,000 m with -1.0% per 100 m above 1,000 m.
Which mechanical loads can the shaft tolerate?
The shaft permits axial loads up to 15 N and radial loads up to 75 N.
