Festo EMMB Series Stepper Motor, 48V Voltage, 1.8° Step Angle - EMMB-ST-57-M-SM, Numeric Part Number: 8156139

This stepper motor provides precise rotational control for motion systems requiring accurate incremental positioning. It operates from a 48V supply and delivers steady performance up to 1000rpm in panel-mounted installations. The unit is constructed to a 57mm frame and is suitable where a sealed IP20 enclosure is acceptable. Certifications include CE, RoHS and cULus among others, reflecting conformity with multiple electrical standards.

Features and Benefits:

• 1.05 Nm holding torque increases positional stability under load
• 5.1A current rating supports higher torque at maintained step resolution
• 1.8° step angle delivers fine incremental movement for indexing
• 0.17 Ω resistance per phase reduces voltage drop in drives
• 6.35mm shaft diameter ensures compatibility with common couplings

Applications

• Suitable for precision indexing tables in assembly systems
• Ideal for laboratory automation requiring repeatable motion
• Used with microstepping drives in CNC auxiliary axes
• Can be used for Camera pan/tilt mechanisms in test rigs

What shaft engagement can be expected for coupling selection?

The shaft has a 6.35mm diameter and 21mm protrusion to accommodate standard clamping couplings.

How does the motor perform at higher rotational rates?

The device is specified to an output speed of 1000rpm which balances torque delivery and step fidelity.

Which mounting arrangement is provided for panel installations?

The design uses panel-mount fixation suitable for flush integration into control enclosures.

What electrical characteristic affects drive tuning and thermal behaviour?

Each winding measures 0.17 Ω resistance per phase, influencing current settings and heat generation.
