Product Description:
The MSK070D-0300-NN-S1-UG1-NNNN is a synchronous servomotor from Bosch Rexroth Indramat in the MSK IndraDyn S Synchronous Motors series. Designed for closed-loop motion systems, the unit delivers precise torque and speed control so that industrial robots, pick-and-place stations, and CNC feed axes can follow commanded trajectories accurately. Its plain shaft supports direct coupling to gearboxes or other drive elements where a simple cylindrical output is preferred. An internally mounted encoder supplies rotor position data to the drive, which helps maintain stable speed regulation during acceleration, deceleration, and dwell periods. This motor type is typically paired with a servo amplifier that closes the current, speed, and position loops in real time.
Thermal management is handled through natural convection, so heat leaves the housing by surface airflow without auxiliary fans. Rotor position is measured with 128 signal periods, and the sensing element is optical, which supports accurate feedback in electrically noisy industrial settings. Signal transmission uses the Hiperface interface, allowing the motor to work with compatible servo drives that process serial position data. For vertical axes or suspended loads, an electrically released brake provides 23 Nm of holding torque when power is removed. This arrangement helps keep the axis stationary during stops and controlled shutdowns.
Connection routing is improved by an encoder plug that is rotatable through 240°, making it easier to direct the cable away from nearby machine parts. Because the feedback device is single-turn, the motor reports angular position within one shaft revolution and is well suited to axes that re-reference within a limited travel range. The motor uses frame size 070 with length code D, giving it a compact mechanical envelope for medium-duty servo applications. Winding code 0300 matches the electrical characteristics expected by compatible drive modules, which supports stable current control during continuous operation. The housing format also fits machine layouts where cable clearance and motor length must stay controlled near guards, slides, or linear guides.
