Festo EMMT Series Stepper Motor, 57mm Frame Size, 48V Voltage - EMMT-ST-57-M-RMB, Numeric Part Number: 8156178

This stepper motor converts electrical pulses into precise rotary motion for controlled-position applications. It is a hybrid design intended for panel-mounted installations and operates where moderate torque and defined step increments are required. The unit is rated for protected indoor environments and is compatible with drive systems supporting the specified voltage and current characteristics.

Features and Benefits:

• 1.8° step angle delivers accurate incremental positioning
• 1.12Nm holding torque enables secure load retention
• 5.4A current rating supports high-power stepping performance
• 1000r/min output speed permits moderately fast motion profiles
• 0.17Ω resistance per phase reduces voltage drop under load

Applications

• Suitable for automated positioning systems in manufacturing
• Ideal for CNC indexing and light motion-control tables
• Used with robotics joints requiring repeatable steps
• Can be used for lab instrumentation requiring precise rotation
• Used for pick-and-place units in assembly lines

What shaft specifications affect coupling options?

The shaft is 6.35mm diameter with 21mm protrusion which suits standard collets and couplers designed for 6.35mm shafts.

What protection and mounting considerations apply?

The enclosure meets IP40, indicating protection from solid objects larger than 1mm, and it is configured for panel-mount installation.

What electrical supply characteristics are required?

The device is specified for a 48V nominal supply and a Peak current capability of 5.4A per phase.

How do pole pair count and step angle influence control?

With 50 pole pairs and a 1.8° increment, it provides fine resolution and predictable microstepping behaviour for precise motion profiles.
