Product Description:

The MSK101D-0300-NN-M1-BG2-NNNN is a synchronous servo motor built by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It converts drive current into controlled torque for indexing tables, gantry axes, and continuous-motion conveyors used in automated equipment. The motor size 101 housing with length D fits standard mounting patterns used in this motor family. Its winding code 0300 matches the electrical characteristics expected by compatible IndraDrive power modules, and the power connector is located on side B for straightforward cable routing. The standard mechanical design does not use optional sealing rings or extended bearing sets, which keeps the configuration straightforward.

This model uses natural convection cooling, so it does not require forced air or liquid jackets. An electrically released holding brake provides 70 Nm of torque to secure vertical loads during standby. The enclosure is rated IP65, which protects the motor against dust and low-pressure water jets. Feedback is transmitted through a Hiperface interface, and the optical system avoids the hysteresis associated with magnetic sensing. The brake is intended to hold the axis at standstill, and the cooling method supports installations that favor simple heat removal.

The encoder provides 128 signal periods per revolution, which allows the drive to interpolate position at high resolution. It also includes multiturn absolute position tracking, so rotor angle is available immediately after power-up even if the axis was moved while de-energized. The motor uses a plain shaft without a keyway for direct-coupled assemblies, and its insulation system meets Class 155 for continuous thermal duty. Ambient operation is permitted from 0–40 °C, which suits typical machine-room conditions. Optical feedback also supports stable speed control at low rpm during precise motion tasks.
