Product Description:
The MSK101E-0300-FN-S2-AP2-RNNN is an IndraDyn S synchronous servomotor engineered by Bosch Rexroth Indramat and supplied within the MSK IndraDyn S Synchronous Motors series. Intended for closed-loop industrial automation axes, the unit converts drive current into precise mechanical rotation for tasks such as positioning tables, pick-and-place modules, and packaging actuators. Motion data are absolute within one turn because the encoder is of the single-turn type, so the drive receives a direct rotor position value after startup. This arrangement supports synchronized motion where accurate speed and position response are required across repeated machine cycles.
Thermal management is provided by liquid cooling, so the stator can support continuous torque without overheating during repetitive acceleration cycles. The integrated coolant jacket interfaces with plant chillers and helps keep winding temperature stable under changing load conditions. An electrically released holding brake provides 70 Nm of static torque, preventing load drift when power is removed. Because the brake disengages when energized, it engages during power loss. Position feedback is supplied by an optical encoder with 2048 signal periods per revolution and an EnDat2.1 interface, enabling precise closed-loop control. The motor uses frame size 101 with length class E, which sets the housing envelope and mounting footprint.
The rotor and stator are machined for improved concentricity, which reduces runout and supports applications that require uniform velocity. Mechanical output is transferred through a shaft with keyway, making the motor suitable for keyed pulleys or rigid couplings. Power connections are arranged on the A-side, which can simplify cable routing in compact machine layouts. The electromagnetic design uses winding code 0300, matching the electrical characteristics expected by compatible IndraDrive controllers. Its electrical values are coordinated with the drive so current regulation remains stable across the operating range.
