Product Description:

The MSK101C-0300-FN-M1-AP2-NNNN is an IndraDyn S synchronous servomotor manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It delivers regulated torque and speed for positioning tables, gantry axes, and other precision stations found in automated packaging, printing, and machine-tool environments. Integrated feedback lets the drive controller maintain tight motion loops during acceleration, deceleration, and steady-state running. In closed-loop servo systems, that behavior supports accurate indexing, contouring, and synchronized motion with other machine axes. Its enclosed construction is suited to industrial installations where compact motor packages are preferred.

Thermal management relies on liquid cooling that circulates through internal stator channels. Operation is permitted only when the FN cooling requirement is met, so the motor must be connected to an external coolant circuit before power-up. This cooling method removes heat from the stator more directly than free-air convection. The unit follows the standard design code, and its power connector is located on the A-side for direct cable routing. An electrically released holding brake supplies 70 Nm of static torque and engages by spring force whenever supply voltage is removed. Position data reach the drive through Hiperface, and the optical measuring system provides 128 signal periods per revolution with a multiturn absolute position value for immediate axis recognition after power-up.

The encoder uses optical scanning, which avoids contact in the measuring system and supports long-term accuracy. A shaft with keyway transmits torque by positive engagement, which helps prevent slip between the motor and the driven mechanism during load reversals. This shaft arrangement is commonly used with hubs and couplings that require secure mechanical engagement. The motor has frame size 101 and length code C, giving it a medium stack depth that balances torque density with installation space and fits standard MSK mounting patterns. Winding code 0300 matches Rexroth drive modules intended for high current at moderate bus voltage.
