Festo
549417
Stepper motor EMMS-ST-87-S-SE
The Festo part number 549417 is an industrial component operating at a nominal voltage of 48 V DC and a nominal motor current of 9.5 A, featuring a 1.8 deg full step stepper angle with a ±5% tolerance. Built with an integrated optical encoder for rotor position sensing, Class B insulation, and an IP54 protection class, this unit delivers a 2.5 Nm motor holding torque, a 2 Nm brake holding torque, and supports a permissible axial shaft load of 65 N alongside a radial shaft load of 200 N. With a product weight of 2,100 g, a mass moment of inertia of rotor and overall mass moment of inertia at power take-off both at 1 kgcm2, and an electrical connector system using a plug, it functions within an ambient temperature range of -10 to 50 °C and storage temperatures between -20 and 70 °C under 45 to 80% relative air humidity while carrying a CE symbol according to the EU-EMV guideline and C-Tick authorization.
