Product Description:
The MSK101E-0300-FN-S2-BP2-RNNN synchronous servomotor is manufactured by Bosch Rexroth Indramat as part of the MSK IndraDyn S Synchronous Motors series. Classified as an IndraDyn S synchronous servomotor, it provides closed-loop rotary actuation for positioning tasks in automated machinery and packaging lines. The motor interfaces with drive controllers to deliver command-based torque and speed, converting electrical input into mechanical rotation for axis control in production cells and material-handling assemblies. This operating profile suits axes that need repeatable motion, stable speed control, and accurate positioning under changing loads.
Thermal management relies on liquid cooling, so the circulating medium removes losses directly from the stator and supports high continuous power density. An electrically released holding brake supplies 70 Nm of static torque to secure the load when power is removed. For position feedback, the motor carries an EnDat2.1 serial interface that transmits incremental and absolute data from an optical scanning system. The feedback disk provides 2048 signal periods, and the single-turn design references absolute position within one mechanical revolution. Because the cooling circuit is integrated into the motor, heat can be managed without relying on external fan airflow around the housing.
The electromagnetic section uses winding code 0300, which sets the electrical characteristics for compatible IndraDrive amplifiers. Power enters on the B-side, which can simplify cable routing when several motors share a conveyor or gantry frame. The motor has size 101 and length E, and it is built with increased concentricity to reduce runout at the shaft face. A shaft with keyway transfers torque to couplings that do not rely on frictional clamping alone. That shaft arrangement is useful for pulleys, gearboxes, and other driven elements that require positive torque transmission. The motor uses the FN cooling class and keeps the mechanical layout consistent with the series.
