Description of AC servo motor EM3G-55

EM3G-55 is a powerful 5500 W AC brushless servo motor. The motor is medium speed and medium inertia model with expanded range of run speeds. Movement accuracy is ensured by high resolution 23-bit optical or 17-bit magnetic absolute encoder. Optional 24 VDC brake is available.

EM3G servo motor series is designed to provide increased operating speed range without reducing output power. This feature significantly expands the range of possible usage applications and in many cases allows excluding a gearbox, improving reliability and reducing overall cost.
