Festo EMMT Series Stepper Motor, 57mm Frame Size, 0.63Nm Holding Torque - EMMT-ST-57-L-RS, Numeric Part Number: 8156180

This stepper motor provides precise incremental motion control for industrial and automation systems. Designed for sealed operation and varied mounting orientations, it delivers consistent stepping performance at moderate rotational speeds. The device operates from a 48V supply and is suited to applications requiring repeatable positioning and controlled acceleration profiles.

Features and Benefits:

• 1.8° step angle delivers accurate positional increments
• 500rpm maximum speed enables moderate-speed motion control
• 0.63Nm holding torque resists external loads during stops
• 5.2A current rating supports sustained torque output
• 0.26Ω phase resistance minimises voltage drop and heat

Applications

• Suitable for indexed conveyor position control systems
• Ideal for servo-replacement in Compact automation cells
• Used with rotary tables requiring repeatable stops
• Can be used for valve actuation in sealed environments

What environmental protection does it offer?

The enclosure is rated IP65, providing dust-tight protection and resistance to water jets.

How can it be mounted in machinery?

It supports mounting in any position to accommodate varied mechanical arrangements.

What are the shaft specifications for coupling?

The output shaft is 6.35mm diameter with a 21mm length to enable standard couplings.

What electrical characteristics affect drive selection?

It requires a 48V supply and the windings present 0.26Ω per phase with a 5.2A current rating for drive tuning.

What mechanical configuration influences torque production?

The rotor contains 50 pole pairs which relate to its stepping and torque behaviour.
