Festo EMMT Series Stepper Motor, 42mm Frame Size, 1.8° step angle - EMMT-ST-42-S-RS, Numeric Part Number: 8156162

This stepper motor provides precise incremental rotation for controlled positioning tasks in electromechanical systems. Designed as a hybrid device with a panel-mount arrangement, it operates at 48V and delivers smooth motion up to 600r/min. The product meets multiple international standards and is suitable for integration where moderate holding torque and defined step resolution are required.

Features and Benefits:

• 1.8° step angle for accurate positional control
• 0.25 Nm holding torque for stable stationary loads
• 1.8A current rating enabling reliable drive performance
• 2.1 Ω resistance per phase limiting Coil heating
• IP40 protection for indoor, dust-limited installations

Applications

• Suitable for CNC Axis motion requiring defined microsteps
• Ideal for precision laboratory instrumentation requiring repeatable positioning
• Used with automated feeders needing steady holding torque
• Can be used for rotary indexing in assembly equipment

What shaft Interface is provided for coupling?

The motor uses a 5mm diameter shaft compatible with standard couplings and fittings.

How deep is the unit for panel integration?

The body depth measures 42mm, allowing Compact panel mounting in constrained assemblies.

What rotational speed can be expected under nominal conditions?

The motor can achieve an output speed of 600r/min when driven within the specified electrical limits.

How many pole pairs are present and what does that affect?

It contains 50 pole pairs, which influences electromagnetic torque characteristics and step response.

Which certifications indicate adherence to safety and performance standards?

The unit carries CE, cULus, IEC 60034, RCM and RoHS recognitions.
