Product Description:

The MSK100D-0300-NN-M2-LP2-RNNN is an IndraDyn S synchronous servomotor manufactured by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. It uses frame size 100 and the D length, giving it the torque and inertia needed for mid-to-high-power axes in automated handling, printing, or packaging cells. As a closed-loop drive element, the motor converts commanded current from a Rexroth inverter into precise rotary motion for position or velocity control on production machinery.

Thermal management is based on natural convection, so heat leaves the housing through surface radiation and airflow without auxiliary blowers; the cooling fins should remain unobstructed during installation. The housing carries an IP65 rating, sealing the stator against dust and low-pressure water jets encountered in factory environments. Operation is permitted from 0 to 40 °C, which supports normal winding and bearing life inside standard control cabinets. Position feedback is provided through an optical encoder that communicates via EnDat 2.1; its internal disk delivers 2048 signal periods, supplying the drive controller with fine incremental data for smooth commutation. The encoder is referenced to the keyed shaft, which simplifies coupling alignment with gearboxes or belt pulleys. A left-side power connector keeps the cable bundle clear of moving machine members.

An electrically released holding brake delivers 70 Nm of static torque, allowing the axis to maintain load position when power is removed. The feedback unit stores multi-revolution position data through its multi-turn absolute design, so homing is unnecessary after emergency stops. The motor uses insulation class 155, which supports elevated winding temperatures during intermittent overloads. The rotor is ground to increased concentricity for low vibration.
