Product Description:
The MSK070E-0300-NN-M2-UP0-RNNN synchronous motor is produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. It is an IndraDyn S synchronous servomotor intended to drive position-controlled axes in industrial automation lines, where accurate torque delivery and electrical feedback are required for coordinated motion. In closed-loop applications, this type of motor supports repeatable positioning, stable speed regulation, and responsive load handling during automated machine cycles.
The motor relies on natural convection to remove heat, so airflow around the housing must be maintained instead of adding forced cooling hardware. Position feedback is handled through an EnDat2.1 optical interface that streams absolute position data from an encoder with 2048 signal periods per revolution, enabling high-resolution drive control. This sensing element is multi-turn absolute, so the controller can read shaft position across multiple revolutions without requiring a homing cycle after power loss. The housing has an IP65 rating that helps block dust ingress and water jets, allowing the motor to be mounted directly on machinery in demanding production environments. The encoder plug can also be rotated through 240°, which helps when cable routing space is limited.
The mechanical interface uses a shaft with a keyway and a design intended to improve concentricity and reduce runout when the motor is coupled to gearboxes or other driven components. The stator uses winding code 0300, which matches compatible drive amplifiers and the electrical characteristics of the E-length frame. Insulation class 155 supports continuous operation as long as internal winding temperature remains within the allowable limit. Reliable service is maintained across an ambient range of 0–40 °C; outside this range, derating or external temperature control is required. The motor is supplied without a holding brake, so any load-holding function at standstill must come from the drive or from external mechanical hardware.
