Product Description:

The MS2E07-E0CNN-CMSK2-NNNNN-NN is a three-phase permanent-magnet servo motor produced by Bosch Rexroth Indramat within the MS2E Synchronous Servomotors series. Intended for closed-loop positioning and speed control, it drives machine axes that require a high dynamic response while maintaining precise feedback through an integrated ACUROlink multi-turn encoder. The motor combines a low-inertia rotor with frame length E, providing a compact, high-torque solution for pick-and-place modules, gantries, and packaging stations in industrial automation.

Mechanical output is supported by a rated holding brake that delivers 36.00 Nm of shaft-locking torque when power is removed, preventing drift on vertical loads. Under continuous duty, the rotor can turn at a nominal speed of 3000 rpm, matching common servo drive frequency ranges. Position data are captured by the Advanced Performance ACUROlink system; the single-turn resolution reaches 20 bits, while the multi-turn counter stores up to 4096 revolutions, enabling accurate homing after power cycles. Because the stator and frame share a common thermal path, the motor relies on self-cooling. The housing surface dissipates heat without auxiliary fans, which simplifies airflow requirements around the installation and eliminates fan-related maintenance.

Protection against airborne particles and low-pressure water jets is rated at IP65, and a shaft sealing ring helps prevent coolant from entering around the keyed output shaft. Internal winding temperature is monitored by a PT1000 sensor that sends real-time data to the drive, allowing derating or shutdown when temperature limits are approached. A B5/IM3001 mounting flange measuring 140 mm supports alignment with industry-standard gearboxes, while the 130 mm centering collar helps minimize runout. The motor is ATEX compliant, permitting installation in zones where explosive atmospheres can occur when all applicable installation requirements are followed. Permitted operating conditions include ambient temperatures from 0 to 40 °C and elevations up to 1,000 m above sea level.
