Festo EMMT-ST Series Stepper Motor, 48V Nominal Operating Voltage, 0.63Nm Holding Torque - EMMT-ST-57-L-R, Numeric Part Number: 8156179

This stepper motor is a Compact industrial actuator designed for precise position control in automation systems. It operates from a 48 V supply and delivers controlled stepping for applications requiring repeatable motion at moderate speeds. The unit is built for varied mounting orientations and includes connection options suited to industrial cabling, with protection that supports harsher environments.

Features and Benefits:

• 1.8° step angle for accurate incremental positioning
• 50 pole pairs enabling fine torque resolution
• 0.26 Ω resistance per phase for predictable electrical loading
• 5.2 A nominal current supporting sustained operation
• IP65 industrial protection for enhanced housing sealing

Applications

• Suitable for pick‑and‑place automation requiring repeatable steps
• Ideal for rotary indexing tables with controlled speed
• Used with motion controllers in laboratory instrumentation
• Can be used for conveyor positioning in manufacturing lines
• Suitable for machine tools requiring stepwise adjustments

What temperatures can it operate within?

It operates between -15 °C and 40 °C with capability to 80 °C using derating of -2%/°C.

What mechanical loads can the shaft accept?

It tolerates axial loads up to 15 N and radial loads up to 75 N.

What electrical Peak capabilities are available?

Peak current reaches 8 A with a Peak torque of 2.1 Nm.

How is the motor connected electrically?

It uses a 12‑core hybrid plug with an M17x0.75 connector pattern.

What dynamic limits affect sustained operation?

Continuous stall current is 6.1 A and thermal time constant is 30 min.
