Product Description:

The MSK070E-0150-NN-M2-UP1-RNNN synchronous servomotor is produced by Bosch Rexroth Indramat and belongs to the MSK IndraDyn S Synchronous Motors series. As an IndraDyn S servomotor, it converts regulated electrical drive output into precise rotary motion for positioning and velocity tasks in industrial automation. This motor is suited for axes that require accurate speed control, repeatable positioning, and stable operation during frequent start-and-stop cycles.

The motor relies on natural convection for heat dissipation, so no external fan or coolant circuit is required when it operates within the permitted ambient range. Its 070 frame size, E-length housing, and winding code 0150 are arranged for the torque and speed demands of common packaging and handling axes. A rotatable 240° encoder connector supports flexible cable routing, while position feedback is supplied through the EnDat2.1 interface. Within the encoder, an optical scanning head resolves 2048 signal periods, and the multi-turn absolute function stores revolutions for power-off position retention. Motion at standstill is secured by an electrically released holding brake with 23 Nm of static torque.

For installation planning, the housing has an IP65 protection rating, so dust and low-pressure water jets cannot reach internal components. The motor uses a shaft with keyway, which supports positive-drive coupling and repeatable alignment under reversing loads. Insulation class 155 permits winding temperatures up to 155 °C without loss of dielectric strength during normal operation. The permitted ambient operating range is 0 to 40 °C when the motor is cooled only by natural convection. The mechanical design also features increased concentricity, which helps reduce radial runout when the shaft is coupled to gearboxes or other driven machine elements.
