Product Description:

The MSK100B-0300-NN-S1-BG1-NNNN is an IndraDyn S synchronous servomotor manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It converts drive-controller commands into precise rotary motion in automated handling, machining, and packaging stations, providing finely regulated speed and torque that support coordinated multi-axis movement on modern production lines. In servo systems, this supports repeatable motion on axes that must accelerate, decelerate, and reverse without losing control accuracy. Winding code 0300 and motor length B give this variant the stator copper volume and thermal behavior used for this motor configuration.

The motor relies on natural convection for heat removal, so mounting positions must allow free ambient airflow around the housing. Frame designation 100 places it in a mid-range size class that balances torque capability with manageable mass for typical gantry or spindle zones. An electrically released holding brake delivers 32 Nm of static torque to secure loads during shutdown or an emergency stop. Position feedback is provided through a Hiperface serial interface that transmits both commutation and operating data to the drive. This feedback system uses an optical scanning method that offers high signal fidelity even under temperature fluctuations and vibration.

The encoder delivers 128 signal periods per mechanical revolution, and internal interpolation by the drive refines this raw pattern for smooth velocity control. Because the measuring system is single-turn, absolute position information is retained only within one rotation. Mechanical power is transferred through a plain shaft, enabling backlash-free coupling to gearboxes or belt pulleys without keyways. All power conductors exit on the motor’s B-side, which aids cable routing where space behind the axis is limited. This cable exit arrangement can help keep the connection area clear when the motor is mounted close to guards or machine frames.
