Festo EMMT Series Stepper Motor, 48V Voltage, 1.12Nm Holding Torque - EMMT-ST-57-M-RS, Numeric Part Number: 8156174

This stepper motor is a compact, sealed hybrid actuator designed for precise position control in industrial settings. It operates at 48V and delivers synchronised stepping performance with a 1.8° step angle, suitable for applications requiring repeatable angular increments and moderate rotational speed. The unit is engineered for installation in any orientation and offers ingress protection for use in harsher environments.

Features and Benefits:

• 1.8° step angle provides accurate incremental positioning
• 5.4A current rating enables sustained drive capability
• 1.12Nm holding torque maintains static loads without drift
• 1000rpm output speed supports moderate-speed motion tasks
• IP65 ingress protection allows operation in dusty or wet conditions

Applications

• Suitable for conveyor indexing systems in factories
• Ideal for automated labelling and pick-and-place machines
• Used with rotary tables requiring repeatable angular steps
• Can be used for Camera pan mechanisms in enclosed environments
• Used for valve actuation where sealed operation is required

What shaft details affect coupling selection?

The shaft diameter is 6.35mm with a length of 21mm which determines rigid coupling and hub choice.

How does electrical impedance influence driver selection?

Resistance per phase is 0.17 Ω so drivers must accommodate low-impedance windings and appropriate current handling.

What certification indications are present for regulatory acceptance?

It carries CE, cULus, IEC 60034, RCM, RoHS and UL E342973 markings supporting recognised conformity.

Can it be mounted in different orientations without performance loss?

Yes

the mount type permits installation in any position while maintaining rated torque and speed.

How many magnetic pole pairs define its stepping resolution?

The device uses 50 pole pairs which contributes to its stepping characteristics and torque profile.
