Product Description:
The MSK071D-0300-NN-S2-UP2-RNNN servomotor is manufactured by Bosch Rexroth Indramat as part of the MSK IndraDyn S Synchronous Motors series. It converts electrical energy into tightly controlled rotary motion for machine tools, packaging lines, and handling robots that demand coordinated position and speed control from a matching IndraDrive amplifier during continuous operation. Frame size 071 and length code D provide a compact footprint without sacrificing torque density, and the electrically released holding brake keeps the axis secure whenever the drive is disabled. The motor is intended for direct coupling to belts, gearboxes, or ball screws inside enclosed automation cabinets.
Thermal management relies on natural convection, satisfying the internal cooling requirement without auxiliary fans or liquid circuits. The optical feedback system provides 2048 signal periods per mechanical revolution and communicates through the bidirectional EnDat2.1 interface, enabling high-resolution absolute position transfer to the controller for closed-loop control. An electrically released brake delivers 30 Nm of holding torque to prevent back-driving on vertical or indexing axes. The housing is sealed to IP65, protecting internal components against dust and low-pressure water jets. The design with increased concentricity reduces runout, and the keyed shaft supports positive torque transmission. Winding code 0300 matches the electrical characteristics used by standard IndraDrive power stages.
The encoder connector is rotatable through 240°, allowing cable routing to clear adjacent hardware and tight mounting surfaces inside the machine frame. The measuring head is a single-turn device, so it supplies an absolute angle within one revolution and lets the drive perform multi-turn counting during operation. Continuous duty is permitted only within 0 to 40 °C, a range that aligns with insulation class 155 for the stator windings. This operating window helps limit thermal rise during extended production cycles.
