Festo EMMT Series Stepper Motor, 1.8° Step Angle, 1.12Nm Holding Torque - EMMT-ST-57-M-RSB, Numeric Part Number: 8156177

This stepper motor is a sealed hybrid unit designed for controlled rotary motion in industrial automation. It operates from a 48V supply and is intended for installation in varied orientations, providing precise incremental movement for positioning tasks while maintaining protection against dust and water ingress.

Features and Benefits:

• 1000r/min output speed delivers consistent rotational performance
• 50 pole pairs enable fine electromagnetic control for smooth motion
• 5.4A current rating supports sustained drive for demanding cycles
• 0.17 Ω resistance per phase reduces voltage drop during operation
• IP65 ingress protection allows use in environments with dust and water

Applications

• Suitable for precision indexing in automation machinery
• Ideal for closed-loop positioning in pick-and-place systems
• Used with rotary tables requiring steady holding torque
• Can be used for conveyor positioning and motion control

What shaft dimensions are provided for coupling options?

The drive shaft is 6.35mm in diameter with a 21mm exposed length.

How does the motor perform when mounted in non-horizontal orientations?

It is specified for installation in any position, allowing flexible machine integration.

Which approvals indicate suitability for industrial installations?

The unit carries CE, cULus, IEC 60034, RCM, RoHS and UL E342973 approvals.

What torque capability should be expected when the rotor is stationary?

The holding torque is specified at 1.12 Nm.

Which enclosure size is relevant for panel or bracket design?

The frame measures 57 x 57mm with a depth of 57mm.
