Product Description:

The MSK101E-0300-NN-M2-AP0-RNNN is an IndraDyn S synchronous servo motor manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It is intended for closed-loop positioning and velocity regulation in industrial handling equipment, packaging stations, and metal-cutting cells. A size 101 frame combined with the elongated E length increases active copper volume while keeping the footprint narrow. This format supports applications that need higher torque density without moving to a wider mounting pattern. The mechanical design provides increased concentricity, which limits shaft runout so couplings remain accurate under cyclic loads and repeated direction changes.

Heat removal is handled by natural convection, allowing the motor to operate without fans or liquid circuits. Position feedback travels through an EnDat2.1 optical interface, providing bidirectional data exchange between the encoder and drive. Inside the measuring system, a grating with 2048 signal periods supplies high angular resolution, while the multiturn absolute function preserves the revolution count after power loss. The motor is delivered without a holding brake, so static load retention must be provided externally when required. Power leads exit on the A-side of the housing, which helps keep the feedback connection accessible and simplifies cable routing in tight machine spaces.

An IP65 enclosure helps keep dust and water jets away from live parts, and torque is transmitted through a shaft with a keyway for secure mechanical engagement. The permitted ambient range of 0 to 40 °C matches common factory conditions, while insulation class 155 allows elevated winding temperatures before insulation aging increases. Winding code 0300 identifies the electrical configuration used with compatible IndraDrive controllers, including the matching voltage constant and current behavior expected by the drive. These features suit installations where protected housing, passive cooling, and accurate shaft coupling are required in the same motor package.
