Festo EMMT-ST Series Stepper Motor, 48V Nominal Operating Voltage, 1.12Nm Holding Torque - EMMT-ST-57-M-R, Numeric Part Number: 8156173

This stepper motor provides precise incremental motion control for industrial automation and positioning tasks. Designed for continuous-duty operation, it runs on 48 V DC and delivers a fine 1.8° step angle for accurate indexing. The motor supports installation at a range of ambient temperatures and altitudes with appropriate derating, and its housing offers enhanced protection against environmental exposure.

Features and Benefits:

• 1.8° step angle enables accurate positional control
• 2600 rpm output speed supports moderate-speed motion tasks
• 5.4 A nominal current gives sustained torque for continuous duty
• 0.17 Ω resistance per phase reduces voltage drop under load
• IP65-rated motor housing protects connections from contaminants

Applications

• Suitable for precision conveyor indexing in manufacturing
• Used for Camera positioning and inspection systems
• Ideal for rotary actuation in assembly stations
• Can be used for valve positioning in process plants
• Used with motion controllers in laboratory automation

What maximum ambient temperature can it tolerate?

It operates between -15 °C and 40 °C and may be used up to 80 °C with a derating of -2% per °C.

What are the current limits for continuous and Peak operation?

Continuous stall current is 6.6 A, nominal current is 5.4 A and Peak current is 8 A.

How does altitude affect performance?

Installation up to 4,000 m is possible

above 1,000 m apply derating of -1.0% per 100 m.

What mechanical loads can the shaft accept?

Permissible axial load is 15 N and permissible radial load is 75 N.
