Product Description:

The MS2N05-B0BNN-CMSG1-NNNN-NN is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MS2N Synchronous Servo Motors series. It serves as a drive element in industrial automation tasks that require accurate position control and stable rotary motion. The motor uses a self-cooling enclosure, standard bearings, and a B5 / IM3001 flange arrangement. It also has a 95 mm centering collar, a 98 mm flange with standard accuracy, frame length B in the MS2N05 size class, a smooth shaft with a shaft sealing ring, a size 1 electrically released holding brake, and a black RAL 9005 varnish finish.

Power and feedback are routed through a rotatable single M23 cable connection, which helps with cabinet cable routing. Over that connection, communication runs at 10 MBaud, and the drive interface uses telegrams with 4 transmit bytes and 20 receive bytes. The integrated multi-turn encoder stores 4,096 absolute revolutions and provides Advanced 20-bit ACURO®Link feedback, while a separate safety channel supplies 9-bit safe-position resolution. Rated mechanical output is available up to 3000 rpm, and the motor uses a shaft diameter of 19 mm. The power conductors support a cross-section of 1.5 mm², and the internal memory retains 7.5 kbytes of OEM parameter data.

For functional safety, the motor is rated to Category 3, PL d and can achieve SIL 2 when it is used with certified drives. The brake is designed for a calculated service life of 20,000,000 cycles, which supports frequent stopping and holding actions on high-duty axes. Application dynamics are supported by a low inertia rotor, which helps the motor accelerate quickly without requiring an oversized drive amplifier. A PT1000 sensor is included for temperature monitoring, so the connected drive can track thermal conditions during operation.
