Product Description:
The MS2E07-C0BQN-CMSG1-NNNNN-NN synchronous servomotor is produced by Bosch Rexroth Indramat for the MS2E Synchronous Servomotors series. This three-phase permanent-magnet motor supplies tightly regulated torque and speed to packaging, material-handling, and machining axes in automated installations. The model combines electronic feedback with a permanent-magnet design to provide closed-loop motion control within the manufacturer’s compatible drive platform.
At its nominal speed of 4000 rpm, the motor uses the Advanced Performance ACUROlink system with a multi-turn encoder that provides a single-turn resolution of 20 bits and stores the absolute position across 4096 mechanical revolutions. The size 07 housing with frame length code C has a 140 mm flange with standard accuracy. Its B5 / IM3001 mounting arrangement uses 11 mm holes on a 165 mm bolt circle, while a 130 mm centering collar maintains concentric alignment. A smooth shaft with a sealing ring works with standard deep-groove ball bearings to achieve an IP65 protection rating. The low-inertia rotor includes a size 1 electrically released holding brake that supplies 20.00 Nm of holding torque when the drive is disabled. A rotatable M23 single-cable interface carries power, encoder, and brake connections, simplifying cable routing within the machine. The assembly is ATEX compliant, allowing installation in applicable explosive atmospheres when all system requirements are satisfied.
Thermal management relies on self-cooling, so the motor does not require an external fan or liquid-cooling circuit. The housing has an RAL 9005 varnish finish that protects its exterior surfaces during routine industrial operation. Continuous operation is permitted within an ambient temperature range of 0 to 40 °C without output derating, and the installation altitude can reach 1,000 m above mean sea level. A built-in PT1000 temperature sensor sends winding temperature data to the controller, allowing the drive to initiate a protective shutdown or adjust the workload when thermal limits are approached. The sealed shaft interface limits the entry of dust and water while helping protect the bearings in demanding operating environments.
