Product Description:
The Bosch Rexroth Indramat MSK100C-0300-NN-S1-AP2-NNNN is an IndraDyn S synchronous servomotor in the MSK IndraDyn S Synchronous Motors series. This permanent-magnet unit supplies precise torque and position control for automated packaging, handling, and metal-cutting equipment. Within such drive systems, it converts regulated inverter current into mechanical rotation while returning encoder data to the controller for closed-loop motion. That arrangement supports repeatable movement during rapid indexing, speed changes, and stop-and-hold sequences.
Thermal management relies on natural convection, so the housing surface must stay exposed to ambient air rather than being enclosed behind panels. The standard design in size 100 with frame length C provides a fixed mounting envelope for medium-duty axes. Winding code 0300 indicates the electrical characteristics used by compatible drive systems. Power enters on the A-side connector, which directs the motor cable toward the drive cabinet. Rotor position is captured by an encoder that uses the Hiperface digital interface; its 128 signal periods per revolution are generated by an optical single-turn sensor, allowing dense commutation data and stable position feedback without multi-turn tracking. An electrically released holding brake delivers 70 Nm of static torque to secure vertical or indexing axes when power is removed, and the sealed housing carries an IP65 rating against dust and water jets.
The motor maintains rated performance within an ambient range of 0–40 °C, so cooling calculations should stay within this window to avoid derating. Output torque is transmitted through a shaft with keyway, enabling positive mechanical coupling to pulleys or gearboxes without relying on friction alone. Class 155 insulation supports winding temperatures up to 155 °C and matches the thermal capacity expected for this cooling method. This makes the motor suitable for servo axes that cycle through repeated starts, stops, and holding periods during normal operation.
