Product Description:

The MSK101D-0300-NN-S1-AP0-NNNN is an IndraDyn S synchronous servomotor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It converts controlled electrical energy into precise rotary motion, allowing indexing tables, gantry axes, and packaging spindles to follow exact position or velocity commands supplied by a drive controller within an automated cell. The unit is delivered in a standard design that pairs a 101 frame with length code D, making it suitable for machinery where compact size and repeatable torque output are required.

Cooling is provided by natural convection, so airflow over the housing removes losses without external fans and supports the motor’s Class 155 insulation rating. An enclosure protection rating of IP65 seals the stator against dust and low-pressure water jets, enabling cabinet-free mounting on the machine frame. Size 101 laminations, length D, and winding code 0300 set the torque density and electrical resistance, while an A-side power connector directs supply cables toward the drive. Position feedback is generated by a Hiperface interface that transmits data from an encoder with 128 signal periods. Its sensing element is optical, which supports high resolution and minimal hysteresis during interpolation.

The feedback module is a single-turn device, meaning it reports absolute angle within one revolution, which is sufficient for most point-to-point axes when the controller executes a homing routine at power-up. The rotor is machined with a shaft with keyway so torque can be locked to pulleys or couplings without relying solely on clamping force. Because the motor is supplied without a holding brake, the application must use mechanical locks or servo torque to secure vertical loads during power loss. Continuous operation is permitted between 0–40 °C, allowing the stator to remain within safe temperature limits when duty cycles follow drive ratings.
