Festo EMMT-ST Series Stepper Motor, 0.63Nm Holding Torque, 48V Nominal Operating Voltage - EMMT-ST-42-L-RSB, Numeric Part Number: 8156171

This stepper motor is a Compact industrial servo‑subtype actuator designed for precise position control in automation systems. It operates from a 48V supply and provides a 1.8° step angle for incremental motion tasks. The unit incorporates an absolute single‑turn rotor position encoder with BiSS‑C Interface for accurate feedback and can be mounted in any orientation. It is intended for use in environments requiring moderate ingress protection and vibration and shock resilience.

Features and Benefits:

• 0.63Nm holding torque delivers secure load retention during stops
• 1.8° step angle enables accurate incremental positioning
• 3.4A nominal current supports sustained torque output
• 3200rpm max output speed allows high‑speed indexing
• IP65 housing protection resists water ingress at enclosure level

Applications

• Suitable for pick‑and‑place automation with position feedback
• Ideal for rotary indexing tables in assembly lines
• Used with motion controllers for conveyor synchronisation
• Can be used for laboratory automation requiring precise steps
• Suitable for transport‑grade equipment exposed to vibration

What encoder resolution is available for position measurement?

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

How does the brake operate electrically and mechanically?

The integral holding brake runs at 24V DC, consumes 0.34A, closes within ≤41ms and releases within ≤28ms.

What thermal and ambient limits apply to continuous operation?

Rated for ambient -15°C…40°C with storage -20°C…70°C, and windings maximum temperature 130°C

derating applies above 40°C at -2%/°C.

What are the electrical winding characteristics relevant to drive design?

Phase resistance is 0.6Ω, phase inductance 0.8mH, voltage constant 10.6mVmin and motor constant 0.162Nm/A.

What mechanical load capacities should be observed on the shaft?

Permissible axial shaft load is 10N and radial shaft load is 28N for reliable operation.
