Festo EMMT-ST Series Stepper Motor, 48V Nominal Operating Voltage, 0.63Nm Holding Torque - EMMT-ST-42-L-RB, Numeric Part Number: 8156170

This stepper motor provides precise positional control for industrial automation and motion systems. It operates at a nominal DC voltage of 48V and is rated for continuous operation within standard ambient ranges. The unit supports high-speed stepping and is designed for varied mounting orientations with protection against shaft-facing contamination. Electrical connection is via a 12-core hybrid plug and it meets recognised safety and environmental directives for industrial installations.

Features and Benefits:

• 1.8° step angle delivers fine positional resolution
• 3200rpm maximum rotational speed enables Faster indexing
• 3.4A nominal current supports sustained torque delivery
• 0.6Ω phase resistance reduces voltage drop in drives
• IP65 for housing protects electronics in harsh environments

Applications

• Suitable for precision indexing tables in assembly lines
• Ideal for feed systems requiring high-speed steps
• Used with closed-loop controllers for servo-class control
• Can be used for packaging machines needing Compact motors
• Suitable for transport-grade installations with vibration exposure

What temperature ranges can the unit withstand during operation?

It operates between -15°C and 40°C with allowance for up to 80°C under derating of -2% per °C.

How does altitude affect performance?

Above 1000 m a derating of -1.0% per 100 m is required, with a maximum installation height of 4000 m.

What braking characteristics are provided for safety stops?

The integral brake uses 24V DC, consumes 0.34A, and has separation and closing times of ≤28 MS and ≤41 MS respectively.

What mechanical loads can the shaft tolerate?

The shaft permits axial loads up to 10 N and radial loads up to 28 N without exceeding specifications.
