Festo EMMB Series Stepper Motor, 48V Voltage, 0.25Nm Holding Torque - EMMB-ST-42-S-SM, Numeric Part Number: 8156127

This stepper motor is a Compact hybrid device designed to deliver precise incremental rotation for motion-control systems. It operates from a 48V supply and provides moderate holding force suitable for controlled positioning tasks. The motor is panel-mounted and rated to IP20, intended for protected indoor environments where accurate stepping and repeatable motion are required.

Features and Benefits:

• 1.8° step angle delivers predictable positional increments
• 600rpm output speed enables moderate-speed motion applications
• 1.8A current rating supports consistent drive performance
• 2.1 Ω resistance per phase affords defined electrical loading
• 50 pole pairs reduce resonance and improve smoothness

Applications

• Suitable for small CNC Axis control and positioning
• Ideal for precision lab automation stages
• Used with rotary encoders for closed-loop positioning
• Can be used for pick-and-place assembly equipment
• Suitable for educational motion-control demonstrations

What shaft specifications are available for coupling?

The motor has a 5mm diameter shaft with 24mm length suitable for standard couplings.

How does the frame size affect mounting choices?

The 42x42mm frame provides a square footprint that suits panel-mounting layouts and Compact assemblies.

What safety and regulatory markings are present?

The product carries CE, cULus, IEC 60034, RCM and RoHS identifiers Plus UL E342973.

What electrical characteristic determines torque at holding?

The combination of 1.8A rated current and 2.1 Ω per phase informs the Coil excitation influencing the 0.25 Nm holding torque.
