Product Description:

The MSK070E-0300-NN-M2-UG0-RNNN from Bosch Rexroth Indramat belongs to the MSK IndraDyn S Synchronous Motors series. As a servomotor for industrial automation, it converts controlled electrical input into precise mechanical rotation for positioning tasks on packaging lines, metalworking centers, and automated assembly systems. Its synchronous design supports accurate speed and position control when paired with a compatible drive controller. The motor is suited for applications that require repeatable motion, stable response during speed changes, and a compact installation profile.

The motor uses winding code 0300 on its stator windings and combines motor size 070 with the extended length E housing to increase torque density without enlarging the mounting footprint. Cooling is handled by natural convection, so heat leaves the frame through surface exposure instead of forced airflow. A rotatable 240° encoder connector eases cable routing at different installation angles. Inside, an optical measuring system with an EnDat2.1 interface produces 2048 signal periods per mechanical revolution, allowing high-resolution feedback to the drive controller. The mechanical output passes through a plain shaft, and the enclosure is rated IP65 to help protect internal components from dust and low-pressure water jets. The motor is supplied without a holding brake, so load-side immobilization must rely on external clamping or continuous servo torque.

The motor uses an internal design focused on increased concentricity, which keeps the rotor’s geometric center closely aligned with the stator to reduce vibration at high speeds. The encoder operates as a Multiturn Absolute device, so the controller can read a unique position value across several mechanical turns without a homing cycle after power-up. The insulation system is rated class 155, permitting continuous winding temperatures up to 155 °C while the ambient temperature remains within 0–40 °C. This thermal capacity supports operation in enclosed machine sections where heat must dissipate through the motor housing.
