Product Description:

The MSK101D-0300-NN-M1-LG0-NNNN is an IndraDyn S synchronous servomotor manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. With size 101 and length D, it delivers controlled torque and speed to automated axes in packaging lines, machining centers, and pick-and-place modules. The motor converts electrical energy from a compatible drive into precise rotary motion for positioning and speed-controlled tasks. Electrical power enters on the left side of the housing, which can simplify cable routing in compact machine frames.

Cooling is provided by natural convection, so the housing dissipates heat without a fan. Position feedback is transmitted through a Hiperface interface, and the encoder provides 128 signal periods per revolution. Because the encoder is optical, it is not affected by stray magnetic fields during operation. The feedback system is multiturn absolute, so position and revolution information remain available after power is removed. A sealing class of IP65 protects the motor against dust and low-pressure water jets. The motor is supplied without a holding brake, so external load holding must be handled by the machine or drive system.

The motor uses a plain shaft, which supports backlash-free couplings for direct drives or precision gearheads. It is intended for continuous operation in ambient temperatures from 0–40 °C, a range that fits most indoor industrial environments. Insulation class 155 allows the winding system to withstand elevated internal temperatures during intermittent overload conditions. Winding code 0300 sets the electrical characteristics expected by compatible Rexroth drive parameters. Passive cooling eliminates the need for auxiliary airflow hardware, which keeps the motor layout simple and avoids fan-related service requirements.
