Product Description:

Bosch Rexroth Indramat manufactures the MSK100A-0300-NN-M2-BP0-RNNN, a synchronous servomotor in the MSK IndraDyn S Synchronous Motors series. The unit is built for precise position and speed control inside automated machines where coordinated motion is critical to product quality. Its permanent-magnet design and digital feedback allow the drive controller to track commanded motion profiles closely, making the motor suitable for multi-axis gantries, pick-and-place stations, and high-speed machining spindles that require consistent torque and dynamic response.

Heat is removed from the stator by natural convection, so no fan or liquid circuit is required. Position data are generated by an optical encoder with 2048 signal periods of base resolution, and the multi-turn absolute measuring system keeps shaft position available across several revolutions after power is restored. Communication travels over the EnDat2.1 bidirectional interface, which reduces cabling while supporting data exchange between the motor and drive. The housing carries an IP65 rating that helps protect internal parts from dust and low-pressure water jets, and the increased concentricity design helps reduce radial runout at the coupling hub for smoother operation.

The motor is supplied without a holding brake, so external clamping must secure vertical axes when power is removed. Frame size 100 and motor length A give the unit a compact form, and winding code 0300 identifies the electrical values used by the matching drive. Torque is transferred through a shaft with a keyway, allowing direct connection to standard hubs. The permitted ambient operating temperature range is 0 to 40 °C, and the power connector on the B-side supports straightforward cable routing in right-hand layouts. Class 155 insulation tolerates elevated copper temperatures during cyclic overloads without damaging the winding varnish.
