Synchronous servomotors of the series EZM for screw drives from a German company Stober Drive Technology they have a large hollow hole for installing a spindle with a diameter for EZM5 models up to 25 mm, for EZM7 up to 35 mm, compact housing design. They are characterized by high dynamics, power and torque values. Two dimensional options are available, a wide range of working configurations, and they are available with types of feedback sensors.
To protect against overheating, PTC thermistors are built in, the engine is cooled by natural convection or using a water heat removal system. On request, the engine can also be equipped with a braking system. The brands of ball screw spindles used are HWIN, THK, Steinmeyer, Kammerer, NEFF, NSK, and other options can also be installed on request. The screw drive is not included in the servo motor package.
