Product Description:

Bosch Rexroth Indramat manufactures the MSK070D-0300-NN-M2-UG1-RNNK. This unit belongs to the MSK IndraDyn S Synchronous Motors series and is built for axis control in packaging, material-handling, and general automation equipment. By converting drive current into precise rotational movement, the motor allows a controller to position loads with high repeatability while returning absolute position data through its integrated encoder. This combination supports controlled starts, stops, and holding behavior in applications that require accurate servo response over repeated motion cycles.

The motor dissipates heat by natural convection, eliminating the need for external fans and keeping the installation layout simple. Position data come from an optical encoder that generates 2048 signal periods per revolution, and the EnDat2.1 serial interface passes digital position and diagnostic data to the drive. The encoder plug is rotatable 240°, which helps route cables in confined machine spaces, and the multiturn absolute design retains turn information when power is removed. For load-holding duties, the electrically released brake provides 23 Nm of static torque so vertical axes can remain stationary at shutdown. The housing is sealed to IP65, which helps protect internal components from dust and low-pressure water jets.

With a frame size of 070, the motor fits mid-range servo installations, and the D-length stator carries the 0300 winding set used for this model. The plain shaft supports direct coupling to gearheads or timing pulleys, and continuous operation is permitted from 0–40 °C under standard plant conditions. Insulation class 155 protects the windings during repeated acceleration and normal thermal cycling. These features support stable motor operation across typical industrial duty cycles without requiring auxiliary cooling hardware.
