Product Description:
The MSK100C-0300-NN-M2-AP2-RNNN is a synchronous servo motor built by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. As a torque source in closed-loop automation, the unit converts drive current into controlled rotary motion for positioning axes, tool spindles, and gantry drives. It is intended for machine functions that require repeatable acceleration, controlled holding behavior, and accurate response to changing load conditions. In automated equipment, this type of motor is commonly used where the drive must track commanded speed and position with stable feedback over a wide operating range.
Cooling is done by natural convection, so heat leaves the housing without forced airflow and no auxiliary fan is required. Position feedback is provided by an optical encoder with the EnDat2.1 interface, and the feedback system delivers 2048 signal periods per mechanical revolution with multiturn absolute position retention for several shaft turns after a power interruption. An electrically released holding brake supplies 70 Nm of static torque, which helps keep a vertical axis stationary when drive power is removed. The brake is useful on lifting or indexing axes where shaft movement at standstill must be limited.
Protection at IP65 helps keep dust and directed water away from the housing, and continuous operation is intended for ambient temperatures from 0–40 °C. The windings use class 155 insulation to withstand elevated internal temperatures, while the output uses a shaft with keyway for positive coupling to pulleys, pinions, or hubs. The power connector is located on the A-side for right-angle cable routing, which can help when cable runs must stay close to the machine frame. The motor uses size 100, length C, and winding code 0300, and it also incorporates an increased concentricity design to improve running accuracy during rotation.
