Product Description:

The MSK070C-0150-NN-S2-UP0-RNNN is a synchronous servomotor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. Within multi-axis machining centers, packaging lines, or pick-and-place stations, this motor supplies precisely regulated torque and speed so closed-loop controllers can hold position or follow motion profiles with high repeatability. Its operating behavior suits applications that require accurate acceleration, steady velocity, and repeatable positioning during continuous production cycles. This makes it suitable for axes that must start, stop, and reverse quickly while maintaining coordinated motion with the rest of the machine.

The stator windings are cooled by natural convection, eliminating external fans and simplifying cabinet ventilation. A housing rated at IP65 prevents dust ingress and guards against water jets, so the unit can be mounted directly on machinery. Signal wiring is simplified by a rotatable 240° encoder connector that can be oriented after installation. Position feedback travels over the EnDat2.1 serial interface, and the optical encoder resolves movement into 2048 signal periods per revolution, enabling fine interpolation inside the drive. The output uses a shaft with keyway, which helps provide slip-free coupling to pulleys or gearboxes. Motor size 070 and length code C indicate the active core dimensions, while winding code 0150 corresponds to the voltage constant and current rating. Continuous operation is permissible between 0 °C and 40 °C without derating, which fits typical factory conditions.

Feedback is absolute over one turn because the encoder is a single-turn design, so multi-turn counting must be handled in the drive or control system. Class 155 insulation allows the copper conductors to reach elevated temperatures without premature aging and helps maintain dielectric strength during cyclic loading. The rotor and stator are machined for increased concentricity, reducing radial runout and improving bearing life when high speeds coincide with low permissible vibration. The motor is supplied without a holding brake, which reduces rotor inertia and supports fast acceleration.
