Product Description:

The MSK070D-0300-NN-M2-UP1-RNNN is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. In automated production cells, it delivers precise rotary motion for tooling heads, indexing tables, and feeder axes by converting controller commands into regulated shaft torque and speed. The motor is suited for closed-loop motion tasks that require accurate positioning, stable velocity control, and repeatable response during frequent start-and-stop cycles. Its synchronous design also supports smooth operation where fast corrections are needed to maintain axis accuracy under changing loads.

This model is cooled by natural convection, so heat is removed through the housing without auxiliary fans or liquid circuits. An enclosure rating of IP65 helps protect the motor against dust ingress and low-pressure water jets, which supports installation close to moving machine elements. For power-off holding, an electrically released brake supplies 23 Nm of static torque, allowing vertical or high-inertia loads to remain fixed when the drive is de-energized. Position data are captured by a multi-turn absolute encoder, and the feedback is transmitted to the drive over the EnDat2.1 serial interface for position, diagnostics, and electronic nameplate communication.

The feedback assembly uses a rotatable 240° connector, which helps with cable routing in compact machine frames. Internal signal generation relies on an optical scanning method that supports accurate phase separation and strong immunity to electrical interference. The motor is intended for ambient temperatures between 0–40 °C, and insulation class 155 supports winding temperatures up to 155 °C during cyclic operation. It also has increased concentricity for reduced runout, a keyed output shaft for positive mechanical coupling, winding code 0300, motor length D, and frame size 070 for medium-power servo axis applications.
