Product Description:
Bosch Rexroth Indramat manufactures the MSK071C-0450-NN-S2-UP1-RNNN, which belongs to the MSK IndraDyn S Synchronous Motors series. This IndraDyn S synchronous servo motor uses its compact 071 frame and C length to deliver tightly regulated torque for positioning axes, pick-and-place heads, and packaging machinery. It is suited for servo applications that require stable speed control and repeatable positioning in a limited installation space. This arrangement supports frequent cycling where the axis must return to the same position with consistent accuracy. Its feedback system and integrated brake support accurate motion during operation and help hold the load when power is removed.
The winding code 0450 sets the electrical constants that affect acceleration behavior and RMS current limits. Cooling is handled by natural convection, so no external blower or liquid circuit is required. The housing has an IP65 protection rating that helps keep out dust and low-pressure water jets, allowing mounting close to the machine in demanding industrial areas. The holding brake provides 23 Nm of static torque, which helps prevent drift when the axis is stopped. Feedback is transmitted through the digital EnDat2.1 interface for absolute position data and integrated parameter memory.
The encoder is an optical single-disk unit with 2048 signal periods per revolution, and it uses a single-turn data format for axes that move through less than one mechanical revolution. This measuring system supports accurate commutation and position evaluation across the operating speed range. For straightforward cable routing, the encoder connector is rotatable through 240°, so conductors can exit toward the cabinet without strain. Improved rotor concentricity reduces radial force fluctuation, and the motor uses a shaft with a keyway for positive-drive couplings. Continuous operation is permitted between 0 °C and 40 °C, while the insulation system meets thermal class 155 for high winding temperatures without premature aging.
