MS2E04-C0BNN-CSSG1-NNNNN-NN by Bosch Rexroth Indramat

The MS2E04-C0BNN-CSSG1-NNNNN-NN is a three-phase permanent-magnet motor produced by Bosch Rexroth Indramat for the MS2E Synchronous Servomotors series. It is intended for precision positioning and velocity control in industrial automation. Its self-cooling housing removes heat without auxiliary fans, so full output is maintained between 0 °C and 40 °C at installation heights up to 1,000 m. Standard deep-groove ball bearings support the rotor, a black RAL 9005 varnish protects the exterior, and a rotatable M23 single-cable connector carries power, brake supply, and digital feedback to the drive. ATEX compliance permits operation in classified explosive environments.

Mechanical interfacing follows the B5 / IM3001 pattern. An 82 mm flange with standard face accuracy seats against a 50 mm centering collar, and four 6.6 mm mounting holes on a 95 mm pitch circle fit common machine interfaces. The motor has frame length code C, motor size code 04, a smooth shaft with a sealing ring, and an IP65 with a shaft sealing ring rating for washdown service. Inside, five pole pairs allow a nominal speed of 3000 rpm, while the rotor can reach 6000 rpm when commanded. Rated phase current is 1.10 A, and the inverter may supply 9.7 A peak. The phase resistance is 10.9 ?, and the back-EMF constant is 105.7 V/1000 rpm. Position data come from a single-turn Advanced Performance ACUROlink encoder with a resolution of 20-bit over one absolute revolution.

The motor delivers 2.80 Nm of standstill torque. It reaches a rated output of 1.62 Nm at a 60 K winding temperature, and it can deliver 12.00 Nm continuously or 13.05 Nm momentarily when the stator is kept at 100 K or 20 °C. The electromagnetic gradient is 1.74 Nm/A, and the low-inertia rotor supports rapid speed changes. A size 1, electrically released holding brake supplies 5.00 Nm of static torque and is energized with 24 V at a current of 0.63 A. A PT1000 sensor monitors stator temperature to protect the windings during demanding duty cycles.
