Festo EMMT Series Hybrid Stepper Motor 48V, 1.12Nm Torque, 1.8 °, 57 mm Frame, 6.35 mm Shaft

This stepper motor provides precise rotary positioning for industrial motion tasks, operating from a 48 V supply and designed for continuous service. It incorporates an absolute single-turn encoder with BiSS‑C Interface for high-resolution feedback and is available with IP40 protection on the shaft and IP65 for the housing and connections, enabling use in environments requiring sealed housings. The unit accepts a hybrid plug connection and conforms to relevant electrical and temperature classes for integration into control systems.

• 1.8° step angle delivering accurate incremental positioning
• 50 pole pairs ensuring fine angular resolution and control
• 1.12 Nm detent torque for secure shaft holding without power
• 5.4 A nominal current enabling sustained rated torque output
• 0.17 Ω phase resistance reducing voltage drop and heating

• Suitable for automated assembly positioning systems
• Ideal for rotary indexing tables in production lines
• Used with motion controllers requiring encoder feedback
• Can be used for robotics joint actuation requiring precision
• Appropriate for lab automation requiring sealed housings

It uses an absolute single-turn magnetic encoder with 16-bit resolution and BiSS‑C interface.

A hybrid plug with M17x0.75 connector and 12 cores is specified for power and signal wiring.

Rated for -15°C…40°C with permissible storage to -20°C…70°C and derating up to 80°C at -2%/°C.

The nominal rotary speed is 1,000 rpm with a maximum mechanical speed of 8,000 rpm and operational limit of 2,600 rpm.

The shaft permits axial loads up to 15 N and radial loads up to 75 N.
