Product Description:

Bosch Rexroth Indramat manufactures the MSK101D-0300-NN-M1-BP3-NNNN. As a synchronous servomotor in the MSK IndraDyn S Synchronous Motors series, it converts electrical input from a drive controller into regulated torque and speed for positioning duties on industrial machinery. The 101 frame size and D length place it in the higher-torque segment of the family, suiting axes that demand repeatable duty cycles without mechanical backlash. When installed in multi-axis gantries or packaging stations, the motor supplies closed-loop motion control that sustains high throughput.

Thermal management relies on natural convection, so waste heat leaves the housing without fans, simplifying cabinet design but requiring clearance around the fins. The sealed enclosure carries an IP65 rating, blocking dust and low-pressure water jets so the unit can be mounted near wash-down zones. Position feedback is provided by an encoder that communicates over the Hiperface interface; its 128 signal periods per revolution give the controller fine angular resolution. Because the scanning system is optical and the scale is multiturn absolute, the drive recovers rotor position after power loss, eliminating homing moves. A B-side power connector supports right-angle cabling, and the standard housing design fits existing Rexroth mounting patterns.

Mechanical coupling is via a shaft with keyway, allowing rigid attachment of gears or pulleys while preventing slippage under load. An electrically released holding brake supplies 120 Nm of static torque to secure vertical axes when the inverter is disabled. The stator follows winding code 0300 and uses Class 155 insulation, maintaining dielectric integrity during continuous duty within an ambient window of 0–40 °C. This combination supports positioning axes that must hold a load securely when drive power is removed.
