Festo EMMT-ST Series Stepper Motor Stepper Motor 48V, 0.63Nm Torque, 1.8 °, 6.35 mm Shaft

This stepper motor is a servo‑type actuator designed for precise position control in industrial settings. It operates from a 48V DC supply and performs reliably over a wide ambient range with derating for high temperatures and installation heights. The motor features hybrid connector electrical interfacing and is intended for continuous‑duty applications where step‑wise motion and repeatable torque are required.

• 1.8° step angle for accurate incremental positioning
• 50 pole pairs for fine resolution and smooth motion
• 1500 rpm maximum rotational speed for moderate‑speed tasks
• 0.26 Ω phase resistance enabling efficient current flow
• 5.2 A nominal current supporting sustained holding torque

• Used with CNC equipment requiring precise indexing
• Suitable for automated assembly requiring repeatable steps
• Ideal for robotics requiring controlled low‑speed torque
• Can be used for conveyor indexing in production lines
• Used for laboratory motion stages needing fine resolution

The winding may reach 130 °C and the motor has a thermal time constant of 30 min for heat dissipation.

Above 1,000 m a derating of -1.0% per 100 m applies and installation up to 4,000 m is permitted.

The shaft region is rated IP40 while the housing including connections is sealed to IP65.

The holding brake operates at 24V DC, consumes 0.38 A, and has a Coil resistance of 63.8 Ω.
