Festo EMMT-ST Series Stepper Motor Stepper Motor 48V, 9.4Nm Torque, 1.8 °, 14 mm Shaft

This stepper motor provides precise motion control for industrial automation and positioning tasks. Designed for continuous‑duty applications, it operates from a 48V DC supply and delivers consistent torque for static and dynamic loads. The unit is suitable for varied mounting orientations and offers both IP40 protection at the shaft and IP65 protection for the motor housing including connectors, enabling use in environments requiring moderate ingress resistance. Ambient and storage temperature ranges accommodate typical industrial conditions while permitting temperature‑related derating at elevated temperatures and altitudes.

• 9.4Nm holding torque delivers secure holding for stationary loads
• 1.8° step angle enables fine positional resolution for accurate control
• 8.4A nominal current rating supports sustained continuous operation
• 0.3Ω phase resistance reduces voltage drop for efficient drive response
• 430rpm maximum output speed allows Rapid indexing where required

• Suitable for automated pick‑and‑place systems requiring precise steps
• Ideal for rotary indexing tables in assembly operations
• Used with closed‑loop drives for positioning in CNC peripherals
• Can be used for valve actuation where sustained holding force is needed

It operates between -15°C and 40°C with permissible operation up to 80°C when applying a -2%/°C performance derating.

Above 1,000 m apply a -1.0% performance derating per 100 m up to the 4,000 m maximum installation height.

The integrated brake uses a 24V DC supply, consumes 0.49A, provides 4.26Nm holding torque and closes within ≤110 ms.

It connects via a 12‑core hybrid plug with an M17x0.75 connector system and Interface code 87A.
