Festo EMMT Series Stepper Motor, 48V Voltage, 1.8° Step Angle - EMMT-ST-42-S-RSB, Numeric Part Number: 8156165

This stepper motor provides precise incremental rotation for motion-control systems, designed for panel mounting in controlled industrial environments. It operates at 48V and delivers repeatable 1.8° steps while offering moderate holding torque suitable for positioning tasks. The unit is intended for applications requiring defined speed control up to 600r/min and a Compact footprint.

Features and Benefits:

• 0.25 Nm holding torque for secure position retention
• 600r/min output speed enabling steady rotational motion
• 1.8A current rating for predictable electrical loading
• 2.1 Ω resistance per phase reducing driver mismatch risk
• IP40 protection level for use in non‑corrosive indoor settings

Applications

• Suitable for small rotary indexing systems
• Ideal for laboratory automation modules
• Used with pick‑and‑place assemblies requiring step control
• Can be used for conveyor positioning in light industry
• Suitable for educational and prototyping rigs

What shaft dimensions affect coupling choices?

The shaft diameter is 5mm and the exposed shaft length is 24mm which informs clamp or hub selection.

What electrical characteristic governs torque per phase?

Phase resistance is 2.1 Ω and the phase current is 1.8A which together determine thermal loading and torque capability.

How does pole pair count influence control resolution?

With 50 pole pairs the motor's electromagnetic configuration affects torque ripple and interaction with drive microstepping.

What mounting considerations should be observed?

The unit is designed for panel mount installation within a 42mm frame envelope to align with panel cut‑outs.

Which approvals apply to safety and regulatory acceptance?

It holds CE, cULus, RCM and RoHS approvals Plus UL E342973 for regulatory conformity.
