Festo EMMT Series Stepper Motor, 57mm Frame Size, 48V Voltage - EMMT-ST-57-L-RM, Numeric Part Number: 8156181

This stepper motor is a hybrid design intended for precise motion control in industrial equipment. It operates at 48V and delivers controlled rotary motion with a 1.8° step resolution suitable for closed-loop or open-loop systems. The device is built for panel mounting and rated to IP40 for protection against solid objects, making it appropriate for many factory and automation environments.

Features and Benefits:

• 1.8° step angle provides accurate positioning for repeatable motion
• 5.2A current rating enables high-drive performance for heavy loads
• 1.86Nm holding torque maintains steady holding under load
• 500rpm maximum speed permits moderately Rapid positioning cycles
• 0.26Ω resistance per phase reduces voltage drop during operation

Applications

• Ideal for CNC Axis positioning requiring fine increments
• Suitable for pick-and-place machinery in manufacturing lines
• Used with automated inspection rigs needing steady holding torque
• Can be used for rotary indexing tables in assembly systems

What shaft size does it use for coupling compatibility?

It uses a 6.35mm diameter shaft suitable for common coupling types.

How deep and wide is the unit for panel recess planning?

The body measures 57mm in depth and 57mm in width for enclosure layout.

What is the exposed shaft length for external mounting considerations?

The shaft extends 21mm from the mounting face to accommodate external fittings.

Which approvals and certifications accompany the motor?

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

How many pole pairs and what IP rating does it have for selection?

It provides 50 pole pairs and an IP40 enclosure rating for dust protection.
