Product Description:

The MSK100B-0400-NN-S1-BG0-NNNN is a synchronous servomotor built by Bosch Rexroth Indramat and placed within the MSK IndraDyn S Synchronous Motors series. In industrial automation, this motor delivers closed-loop torque, speed, and position control for packaging equipment, gantry axes, and material-handling stations where accurate motion sequences are required. Its synchronous design allows the paired drive to regulate motion precisely during acceleration, steady operation, and stopping, which supports repeatable axis performance in automated systems. It can serve indexing, transfer, and positioning duties where consistent response is needed across changing loads.

Heat generated by the windings is removed through natural convection, so the unit can be mounted without external blowers, although enclosure spacing must allow unobstructed airflow. Rotor position feedback is supplied by a Hiperface-compatible encoder, and the interface uses differential signals on shielded twisted pairs to reduce electrical noise between the drive and motor. Inside the scanning head, optical sensing tracks produce 128 signal periods per mechanical revolution, and the feedback electronics interpolate them for high-resolution commutation. Because the measuring system is single-turn, absolute position is retained within one revolution, while multi-turn tracking is handled by the external controller. This feedback arrangement supports smooth low-speed control and stable servo response during positioning tasks. Winding code 0400 is selected for general-purpose duty cycles.

The housing carries an IP65 rating, so dust ingress is blocked and low-pressure water jets do not disrupt operation within the approved 0 to 40 °C ambient range. A hardened plain shaft transfers torque to backlash-free couplings, and the motor is delivered without a holding brake, which reduces inertial load during frequent start-stop cycles. Size 100 and length code B indicate the stator geometry, and the B-side power connector helps route cables in machine layouts that share a common feed direction. Class 155 insulation supports winding temperature endurance during cyclic acceleration, and the standard design avoids the need for custom sealing or auxiliary cooling accessories. The sealed housing and simple shaft arrangement suit machines that need straightforward mechanical integration and dependable operation in routine industrial environments.
