Product Description:
The MSK070C-0450-NN-S2-UG1-RNNN is a synchronous servomotor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. As a drive element in industrial automation, it converts regulated electrical energy from a compatible drive controller into precise rotary motion for axes that require high positional repeatability. Its synchronous design supports accurate speed and position control in applications such as packaging stations, pick-and-place gantries, and CNC tooling. The motor also uses an increased-concentricity shaft assembly to reduce runout where tight mechanical tolerances are important.
Thermal management relies on natural convection, so the motor does not require an external fan for cooling. Position feedback is delivered through an optical encoder with the EnDat2.1 serial interface, which supports direct communication with the matching control electronics. The encoder disk provides 2048 signal periods per revolution, and the single-turn design retains absolute position information within one shaft rotation. The encoder plug can be rotated by 240 degrees to simplify cable routing in confined machine layouts. Motion can be held by an electrically released brake that provides 23 Nm of torque when the axis must remain stationary after power is removed.
The housing is sealed to IP65, helping protect internal components from dust and low-pressure water jets. Power is transmitted through a plain shaft, which supports direct coupling to pulleys or gearboxes, and the rotor is balanced for the C-length version of the 070 frame to help reduce vibration. Continuous operation is permitted within an ambient range of 0–40 °C, and insulation class 155 supports winding temperatures associated with dynamic duty cycles. The 0450 winding code and 070 frame size place the motor in a compact servo format intended for precise rotary motion.
