Product Description:
The MSK101C-0300-NN-M1-AG2-NNNN is an IndraDyn S synchronous servomotor manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. This motor converts drive-supplied three-phase power into regulated torque for axis control in industrial automation. An optical multi-turn absolute encoder delivers position data immediately after power cycling, allowing precise homing-free operation in machining centers, pick-and-place modules, and other coordinated motion systems.
Its thermal management relies on natural convection, a passive cooling mode that dissipates heat without fans or liquid circuits. The housing carries an IP65 rating, blocking dust ingress and low-pressure water jets during washdown or open-frame installation. An electrically released brake supplies 70 Nm of static holding torque so vertical axes can remain locked when power is removed. Position feedback granularity is provided by the encoder’s 128 signal periods, permitting fine velocity control at low speeds. Windings built to insulation class 155 tolerate elevated copper temperatures, supporting continuous-duty operation. The unit follows the Standard design code, uses a plain output shaft for direct coupling, mounts its power connector on the A-side, and requires the Cooling FN installation condition so airflow around the fins remains unobstructed.
Communication with the drive controller occurs through the Hiperface interface, ensuring synchronous transmission of position and diagnostic data. The motor operates within an ambient range of 0–40 °C, maintaining stated performance without derating in typical factory conditions. The motor has a frame size of 101 and a length code of C, giving it a balanced inertia profile for mid-power axes. Winding code 0300 sets the resistance and inductance values expected by compatible MSK drives. The optical encoder supports stable servo feedback when the brake is released and the axis moves through programmed acceleration profiles.
