Product Description:

The MSK100B-0400-NN-M2-AG0-RNNN is an IndraDyn S synchronous servomotor built by Bosch Rexroth Indramat and included in the MSK IndraDyn S Synchronous Motors series. In automated machinery, this motor acts as a direct-drive actuator that delivers tightly regulated speed and position to axes such as gantry heads, tool spindles, or pick-and-place arms. It is suited to applications that need accurate starts, stops, and speed changes during repetitive motion. The motor has a 100 mm frame with B length, and its power connector is located on the A side to route supply leads toward the driven machine.

The unit is cooled by natural convection, so heat leaves the housing without forced airflow, which helps keep the installation simple and avoids external fans. A high-precision optical feedback system connects through the EnDat2.1 interface and provides 2048 signal periods per revolution for fine incremental data. The encoder is Multiturn Absolute, so shaft position is retained over many revolutions even after power loss and startup can proceed without a homing routine. The motor is rated IP65, which helps keep out dust and low-pressure water jets on open production lines. Increased concentricity in the mechanical design minimizes runout between the rotor and stator, supporting smooth torque generation during precision moves.

The specified operating range of 0–40 °C lets the motor operate on factory floors without separate climate control in typical indoor production areas. The motor uses a plain shaft for torque transfer where keyed or tapered couplings are unnecessary, and it comes without a holding brake when external clamping is used. Thermal insulation class 155 supports winding temperatures up to 155 °C during continuous duty. Winding code 0400 indicates the electrical constants used in the drive parameter set.
