Festo EMMT-ST Series Stepper Motor, 48V Nominal Operating Voltage, 1.12Nm Holding Torque - EMMT-ST-57-M-RSB, Numeric Part Number: 8156177

This stepper motor is a 48V industrial servo stepper motor designed for precise positioning and controlled rotary motion in automated systems. It operates reliably across a wide ambient range and supports hybrid plug electrical connection with a 12‑core M17x0.75 connector. The unit incorporates an absolute single‑turn encoder with BiSS‑C Interface for accurate rotor feedback and an integrated holding brake for secure static positioning.

Features and Benefits:

• 1.8° step angle motor delivers predictable full‑step movement
• 5.4A current stepper motor provides sustained nominal torque
• low resistance 0.17Ω stepper motor reduces I2R losses during steady state
• high torque 1.12Nm stepper motor maintains position under load
• 50 pole pair stepper motor enables fine electromagnetic control

Applications

• Suitable for precision pick‑and‑place machines
• Ideal for synchronised conveyor indexing systems
• Used with motion controllers requiring BiSS‑C feedback
• Can be used for rotary table positioning tasks
• Used for closed‑loop robotics joints requiring holding brake

What encoder resolution is available for position feedback?

The encoder provides 16‑bit resolution with 65,536 position values per revolution.

How does the brake perform electrically and mechanically?

The brake runs on 24V DC, consumes 0.38A, delivers 1.74Nm holding torque and closes in ≤97ms.

What environmental protection does the unit offer?

The shaft area is IP40 while the motor housing including connections is IP65 protected.

What are the thermal limits for continuous operation?

Continuous rating is S1 with max winding temperature 130°C and thermal time constant 27 min.
