Product Description:

The MSK070C-0150-NN-M2-UP0-RNNN is a size 070, length C synchronous servo motor produced by Bosch Rexroth Indramat in the MSK IndraDyn S Synchronous Motors series. Its increased concentricity design keeps shaft runout low, and winding code 0150 suits medium-torque drive tasks where stable rotation and repeatable alignment are important. The motor serves as a closed-loop actuator that converts inverter current into accurate rotary motion for automated packaging, printing, and material-handling cells, where consistent positioning supports steady process timing.

In operation, the housing is sealed to IP65, so dust and water jets cannot reach the stator windings. Heat is removed through natural convection, so no external blower or liquid circuit is required, though airflow around the frame must remain unobstructed. The feedback device connects through a rotatable 240° connector that carries the digital EnDat2.1 protocol, allowing the drive controller to read position values and electronic nameplate data on a single shielded cable. Inside the sensor, an optical scanning head tracks a disk that yields 2048 signal periods per revolution, providing fine incremental resolution for velocity loops and smooth torque production under low-speed conditions.

The encoder stores absolute position across power cycles because it is a multi-turn absolute device, eliminating the need for homing after shutdowns and allowing the axis to recover its position immediately at startup. Mechanical coupling is through a shaft with keyway, which allows positive torque transfer to gearboxes or pulleys without relying only on friction. Continuous operation is permitted within an ambient range of 0 to 40 °C, and the motor uses insulation class 155 to support winding temperatures up to 155 °C before thermal derating is required. Because the unit is supplied without a holding brake, any static load retention must be handled by the drive or by external mechanics.
