Festo EMMB Series Stepper Motor, 48V Voltage, 2.4Nm Holding Torque - EMMB-ST-87-S-SS, Numeric Part Number: 8156150

This stepper motor delivers precise positional control for industrial automation and motion systems. It is a hybrid design intended for panel mounting and provides controlled stepping with a 1.8° increment. The unit operates at 48V and is suitable for applications requiring moderate holding force and accelerated output speed while maintaining protection against solid ingress consistent with its IP20 rating.

Features and Benefits:

• 1.8° step angle for accurate incremental positioning
• 48V supply enabling stable torque delivery
• 2.4Nm holding torque for secure stationary loads
• 6.9A current rating supporting high-drive performance
• 800rpm maximum speed for Rapid motion cycles

Applications

• Suitable for precision conveyor indexing systems
• Ideal for pick-and-place machinery requiring repeatability
• Used with rotary tables for controlled angular positioning
• Can be used for laboratory automation actuators
• Suitable for panel-mounted motion control assemblies

What shaft dimensions does the motor provide for coupling compatibility?

The motor uses an 11mm diameter shaft with a 30mm exposed length suitable for common couplings and clamping hubs.

How does the winding characteristic affect drive selection?

Each phase has a resistance of 0.13 Ω, which influences current demand and driver heat dissipation when selecting a compatible stepper driver.

What mechanical configuration supports installation to control panels?

The unit is designed for panel mounting with an 87mm frame compatible with standard panel cut-outs and mounting patterns.

What electrical and safety approvals accompany the product?

It holds CE, cULus, IEC 60034, RCM and RoHS recognitions, Plus a UL E342973 listing.

How many pole pairs does the rotor contain and what does that imply?

The rotor comprises 50 pole pairs, affecting magnetic pole count and stepper electromagnetic performance.
