Product Description:

The MSK071D-0300-NN-M1-UP1-NNNN is an IndraDyn S synchronous servo motor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. As a compact rotary actuator, it converts commanded drive current into torque for positioning, indexing, and continuous-motion axes in automated machinery. This type of motor is commonly used where repeatable motion, stable speed control, and accurate stopping behavior are needed during cycling, transfer, or synchronized machine movement. It combines absolute feedback with an electrically released holding brake, allowing closed-loop operation and secure load holding when drive power is removed.

The motor is cooled by natural convection, so heat dissipates through the housing without forced airflow, which simplifies installation and reduces acoustic noise. Feedback is transmitted over the Hiperface interface, and the encoder provides 128 signal periods for fine angular resolution during motion control. The sensing principle is optical, using a light-based code disk read by photodetectors for repeatable position detection. The encoder uses multiturn absolute feedback, so position is retained through 4,096 mechanical revolutions without a homing cycle after power loss. For load holding, the electrically released brake provides 23 Nm of static torque to prevent unintended motion when the drive is disabled.

The output uses a shaft with a keyway, which provides positive torque transfer to pulleys, couplings, or gearboxes in applications that need a secure mechanical connection. The motor has a frame size of 071, placing it in a medium-power range that balances inertia and installation space on compact machine axes. Winding code 0300 corresponds to the electrical constants used by the paired drive for rated torque operation within its voltage range. A rotatable 240° encoder connector supports flexible cable routing, and the motor uses a standard housing design that fits typical machine layouts.
