Product Description:

The MSK100B-0300-NN-S2-BP0-RNNN is an IndraDyn S synchronous servomotor from Bosch Rexroth Indramat in the MSK IndraDyn S Synchronous Motors series. As a rotary actuator, it converts drive current into precise motion for positioning axes, conveyor sections, or tool spindles in automated machinery. The size-100 frame and B length give it a medium torque class that balances inertia with compact installation. Used with Rexroth drive controllers, the unit closes high-resolution feedback loops so production equipment can maintain repeatable speed, angle, and acceleration profiles. This makes the motor suitable for applications that require steady motion control in packaging, handling, and general automation equipment.

Cooling relies on natural convection, so heat is dissipated through the housing fins without forced airflow, which is useful in sealed cabinets. Mechanical accuracy is supported by an increased concentricity design, limiting shaft runout and reducing vibration transfer to attached loads. For positional feedback, the motor carries an optical encoder that communicates through the EnDat2.1 interface. The sensor delivers 2048 signal periods per revolution, which the controller interpolates for fine angular resolution. Because the encoder is single-turn, it reports absolute position within one mechanical turn and removes the need for a homing routine at startup.

Operation is specified without a holding brake, so stopping torque must be supplied by the drive or by an external locking device when power is removed. The power cables attach on side B, allowing compact side-entry routing inside multi-axis installations. This cable position can also help reduce routing congestion where several motors are mounted close together. Torque is transferred through a shaft with keyway, a common connection that helps prevent slip between the rotor and the coupling under load surges. The 0300 winding code identifies the electrical winding arrangement used for this size-100 motor, and it matches the motor to compatible IndraDrive amplifiers for appropriate current selection.
