MS2E03-B0BYN-CMSK0-NNNNN-NN by Bosch Rexroth Indramat

The MS2E03-B0BYN-CMSK0-NNNNN-NN is a three-phase permanent-magnet servo motor manufactured by Bosch Rexroth Indramat within the MS2E Synchronous Servomotors series. It provides precise motion control for automated handling, packaging, and processing axes that require high rotational speed with low rotor inertia. The motor integrates an Advanced Performance ACUROlink multi-turn encoder and a single M23 hybrid cable, allowing the drive controller to receive power, position data, and feedback through one routed lead.

The motor reaches a nominal speed of 9000 rpm and can sustain that speed up to its mechanical limit. A peak torque of 3.75 Nm is available for rapid acceleration, while continuous duty at a 60 K temperature rise is limited to 0.35 Nm with 0.72 A. This operating point corresponds to 0.21 kW of shaft power. Standstill torque is 0.73 Nm at 1.31 A, and a winding resistance of 14.3 ? works with a voltage constant of 36.9 V/1000 rpm. The rotor has low inertia for fast but controlled speed changes, the enclosure is rated IP65, and the motor is ATEX compliant for use in potentially explosive zones.

Mechanical installation uses a 40 mm centering collar, a 58 mm flange with standard accuracy, a 63 mm bolt circle, and 4.5 mm mounting holes that match the B5 / IM3001 pattern. Frame length code B and motor size code 03 keep the package compact, while the keyed shaft is sealed and deep-groove ball bearings support the output side. Self-cooling permits ambient operation from 0 to 40 °C at altitudes up to 1,000 m. Overload current reaches 7.25 A. The torque constant is 0.61 Nm/A, and the windings have an inductance of 20.22 mH monitored by a PT1000 sensor. A varnish coat in RAL 9005 protects the surface, the encoder provides 20-bit single-turn resolution with 4,096 absolute revolutions, and the motor is supplied without a holding brake.
