Product Description:

The MS2E04-C0BNN-CMSK1-NNNNN-NN is a three-phase permanent-magnet servo motor manufactured by Bosch Rexroth Indramat for the MS2E Synchronous Servomotors series. Supplied as a size-04 unit with frame length code C, it drives precision axes in hazardous areas while meeting ATEX conformity requirements. The motor uses an Advanced Performance ACUROlink multi-turn encoder that offers 20-bit single-turn resolution across 4,096 revolutions, providing high-resolution position control for industrial automation tasks.

The motor delivers a continuous torque of 1.62 Nm at 3,000 rpm while drawing 1.1 A, resulting in an output of 0.55 kW. It has a standstill torque of 2.80 Nm and handles a peak current of 9.7 A, while maximum torque reaches 13.05 Nm at 20 °C. Overspeed is limited to 6,000 rpm, and electromagnetic conversion follows a torque constant of 1.74 Nm/A with a voltage constant of 105.7 V per 1,000 rpm. Low rotor inertia supports rapid acceleration, and the self-cooled housing removes heat without an external cooling system. Power and feedback share a rotatable M23 single-cable connector, while deep-groove ball bearings support the keyed shaft and its sealing ring. The B5 / IM3001 flange measures 82 mm across and has a 50 mm centering collar, a 95 mm pitch circle, and 6.6 mm mounting holes.

An electrically released size-1 brake rated at 24 V DC supplies a holding torque of 5.00 Nm, preventing axis drift when power is removed. The total motor mass with this brake is 4.4 kg, and the assembly has an ingress protection rating of IP65 because of its shaft sealing ring and enclosed housing. Continuous operation is permitted from 0 to 40 °C without derating and at elevations up to 1,000 m above mean sea level. A PT1000 sensor monitors the winding temperature to support thermal protection during operation. The housing has a black RAL 9005 varnish coating that protects its external surfaces. The flange uses standard accuracy to support consistent alignment with compatible machine interfaces.
