Festo
526726
Servomotor MTR-AC-55-3S-GB
This Festo industrial component features a planetary gear unit with a 4:1 gear unit ratio, maintaining a torsional backlash of 0.33 degrees or less alongside a nominal output speed of 1,125 1/min for 50% ED and 1,100 1/min for 100% ED. It operates with a nominal motor power of 468 W, a nominal voltage DC of 325 V, a nominal motor current of 1.4 A, a peak current of 6.4 A, and a continuous open-circuit current of 2.15 A, utilizing a resolver rotor position sensor, a PTC resistor for temperature monitoring, and a brake requiring 24 V DC operating voltage and 11 W power consumption. The assembly achieves a nominal rotary speed of 6,800 1/min, a maximum speed of 8,090 1/min, a motor constant of 0.457 Nm/A, insulation protection class F, and CE compliance according to the EU low voltage guideline, while supporting storage temperatures from -10 to 60 °C.
