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
• 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
