Festo EMMT Series Stepper Motor, 48V Supply Voltage, 0.63Nm Holding Torque - EMMT-ST-57-L-RSB, Numeric Part Number: 8156183

This stepper motor is a hybrid design intended for precise positional control in industrial and automation contexts. It operates from a 48V supply and is capable of delivering controlled motion at speeds up to 500rpm while maintaining ingress protection suitable for challenging environments. The unit is certified to multiple international safety and materials standards for use in machine assemblies and equipment.

Features and Benefits:

• 1.8° step angle delivers fine incremental positioning
• 50 pole pairs enable smooth torque production
• 5.2A current rating permits sustained motor drive
• 0.26 Ω resistance per phase reduces phase voltage drop
• IP65 rating allows operation in dusty and wet settings

Applications

• Suitable for CNC Axis positioning systems
• Used with rotary indexing tables for repeatable steps
• Ideal for laboratory automation handling tasks
• Can be used for conveyor start/stop positioning
• Suitable for valve control in process equipment
