Product Description:

The MSK101D-0300-NN-S1-AG0-NPNN is an IndraDyn S synchronous servo motor manufactured by Bosch Rexroth Indramat and included in the MSK IndraDyn S Synchronous Motors series. In multi-axis machining centers, pick-and-place gantries, or packaging stations, this motor supplies precisely commanded torque so the associated drive controller can synchronize position, velocity, and acceleration with other axes on the machine. The motor carries no integrated brake, so static load holding must be provided externally when required. This operating role makes it suitable for applications that need repeatable motion during indexing, cutting, sealing, or transfer sequences.

The housing is built for flange assembly (B5), allowing the motor face to mount directly to a gearhead or machine wall while the stator remains stationary. Cooling is handled through natural convection, so airflow around the exterior fins removes heat without auxiliary blowers or liquid circuits. Electrical power reaches the stator windings through an A-side connector, and the rotor couples to loads with a plain shaft when tapered or keyed hubs are unnecessary. The motor has size code 101 and length code D, which correspond to the active iron stack and total body depth. Inside the sealed encoder chamber, an optical system uses a Hiperface interface and resolves rotor position in 128 signal periods, providing feedback for tight current-control loops.

The motor has an IP65 protection rating, which helps keep internal components free of dust ingress and water jets encountered on production floors. The encoder is a single-turn device, reporting the absolute angle within one mechanical revolution, which is suitable for homed applications that do not require multi-turn data retention. Because the encoder retains position only within one revolution, the machine normally establishes its reference position during startup. Continuous operation is allowed from 0 to 40 °C, a range coordinated with the motor's thermal class 155 insulation system that tolerates winding hot-spot temperatures up to 155 °C. Winding code 0300 identifies the coil impedance and rated torque constant, allowing the drive to use matching current limits.
