Product Description:
The MSK100C-0300-NN-S2-BP0-RNNN is a synchronous servomotor manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. As a drive element, it converts electric power into controlled rotary motion for packaging, metal-cutting, and material-handling lines. It can be paired with CNC controllers and motion modules so axes respond accurately during indexing, feed control, and synchronized machine movements. That operating role makes the motor suitable for applications that require repeatable acceleration and stable positioning under changing loads.
This model uses natural convection cooling, so heat leaves the housing through surface radiation and airflow without external fans. Its housing is sealed to IP65, which blocks dust and water jets so it can be mounted close to processing equipment. Continuous operation is permitted at ambient temperatures of 0–40 °C, allowing installation in standard factory environments. Position feedback comes from an optical encoder that generates 2048 signal periods per revolution, and the digital data stream is transmitted through the EnDat2.1 interface. This arrangement gives the drive controller absolute position values for tight loop control after power interruptions.
Within the encoder assembly, the light-grating system is optical and uses a single-turn configuration, so one electrical revolution of feedback equals one mechanical revolution of the shaft. The rotor uses an increased concentricity design to reduce radial runout, and the output is a shaft with a keyway for positive torque transfer to pulleys or couplings. This style supports direct mechanical engagement when the motor is connected to keyed hubs or similar drive components. This unit is supplied without a holding brake, so external clamping or drive torque must secure the load when power is removed. The motor has size 100 and length code C, and winding code 0300 matches drives that supply the required current profile. A B-side power connector simplifies cable routing, while thermal class 155 insulation supports winding temperatures suitable for continuous industrial duty.
