Product Description:

Bosch Rexroth Indramat manufactures the MS2E07-E0CNN-CMSG2-NNNNN-NN as part of the MS2E Synchronous Servomotors series. The unit is a three-phase permanent-magnet servo motor built for precise motion control in industrial automation. A multi-turn Advanced Performance ACUROlink encoder supplies absolute position data to the connected servo controller. A size 2 electrically released holding brake secures the shaft when power is removed. Combined with a low-inertia rotor and deep-groove ball bearings, the motor supports rapid start-and-stop cycles in indexing tables, robots, and material-handling axes.

The motor operates at a nominal speed of 3,000 rpm, permitting high throughput without exceeding the speed limits of many standard mechanical transmissions. When motion must be arrested, the brake provides up to 36.00 Nm of holding torque, which helps prevent vertical loads from moving while power is unavailable. The encoder provides 20-bit resolution per revolution, allowing the servo controller to calculate fine position changes without an external feedback device. The housing has an IP65 protection rating and includes a shaft sealing ring, protecting internal components from dust and low-pressure water jets. Its mounting flange uses a 140 mm B5 pattern with a 130 mm centering collar for accurate alignment with compatible gearboxes and machine surfaces.

The encoder records up to 4,096 complete shaft revolutions, preserving unambiguous absolute position data after a power cycle. Thermal management relies on self-cooling, eliminating the need for an external fan and keeping the motor within the compact E-frame envelope. Rated-load operation is permitted at ambient temperatures from 0 to 40 °C, while installation is supported at elevations up to 1,000 m. An internal PT1000 sensor monitors motor temperature so the drive can respond if winding heat approaches an unsafe level. The motor has ATEX compliance for appropriate applications where potentially explosive atmospheres may be present, subject to the required installation practices. Power, brake, and feedback conductors use a single-cable connection with a rotatable M23 plug, allowing the connector orientation to suit the available routing space. The smooth shaft supports clamp-style couplings, while 11 mm mounting holes arranged on a 165 mm bolt circle accommodate attachment to pumps, linear drive screws, or gearheads.
