Festo EMMT Series Stepper Motor, 57mm Frame Size, 1.8° Step Angle - EMMT-ST-57-L-RMB, Numeric Part Number: 8156184

This stepper motor provides precise incremental motion control for panel-mounted electromechanical systems. It operates from a 48V supply and is designed with a hybrid construction to deliver high-resolution stepping and dependable rotational performance in applications requiring moderate torque and controlled speed.

Features and Benefits:

• 1.86Nm holding torque delivers stable shaft positioning
• 5.2A current rating supports sustained drive performance
• 500rpm output speed enables moderate-speed motion tasks
• 0.26Ω resistance per phase allows predictable thermal loading
• 50 pole pairs provide fine phase resolution for accuracy

Applications

• Suitable for automated pick-and-place systems requiring steady hold
• Ideal for laboratory instruments demanding controlled rotation
• Used with rotary indexing tables for repeatable positioning
• Can be used for precision feeders in manufacturing lines

What shaft Interface dimensions are available for coupling?

The shaft uses a 6.35mm diameter with a 21mm exposed length to accommodate standard couplings.

What protection level does the enclosure provide?

The enclosure meets IP40, offering protection against solid objects greater than 1mm but not against liquids.

What mounting arrangement is required for installation?

The device is configured for panel-mount installation, permitting direct attachment to control panels or mounting plates.

Which standards approvals are associated with the unit?

It carries CE, cULus, IEC 60034, RCM and RoHS designations along with UL E342973 registration.
