Festo
549418
Stepper motor EMMS-ST-87-S-SB
This Festo industrial component operates on a 48 V nominal DC voltage with a 9.5 A nominal motor current, featuring a 1.8 deg stepper angle at full step and a ±5% stepper angle tolerance. It provides a motor holding torque of 2.5 Nm, a brake holding torque of 2 Nm utilizing a 24 V DC operating voltage and 11 W power consumption, and achieves an IP54 protection class with Class B insulation. Designed with a permissible radial shaft load of 200 N, an axial shaft load of 65 N, and an overall mass moment of inertia at power take-off of 1.07 kgcm2, the unit functions within an ambient temperature range of -10 to 50 °C and relative air humidity of 45 to 80%.
