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

This stepper motor is designed for precise position control in industrial drive applications, operating from a 48V DC supply. It delivers consistent step performance with a 1.8° step angle and is configurable for diverse mounting orientations. The unit is suitable for environments requiring sealed housings and hybrid-plug electrical connection, and it meets recognised electrical and safety standards for industrial use.

• 9.4Nm holding torque for high-load positioning capability
• 1.8° step angle for accurate incremental movement
• 8.4A nominal current for sustained operational duty
• 0.3Ω phase resistance enabling efficient current delivery
• 430rpm maximum rotational speed for moderate-speed applications

• Suitable for automated assembly positioning tasks
• Ideal for conveyor indexing in manufacturing lines
• Used with motion-control systems requiring high torque
• Can be used for rotary actuators in test rigs
• Useful in robotics joints needing precise step control

The winding may reach 130°C maximum and the motor is rated for continuous duty class S1 with a thermal time constant of 37 min.

Above 1000 m, expect a derating of -1.0% per 100 m

The motor housing is IP65 rated

The shaft permits axial loads up to 60 N and radial loads up to 220 N with a maximum mechanical speed of 7000 rpm.
