Product Description:
The MSK075E-0300-NN-M3-UG0-NNNN is a synchronous servomotor built by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It converts electrical energy into regulated torque and speed for positioning axes, gantries, and packaging machinery. In closed-loop systems, the motor works with compatible drive controllers so position and velocity can be corrected continuously during operation. This supports repeatable motion in automated equipment during indexing, feeding, and positioning tasks.
This model relies on natural convection for heat dissipation, so airflow around the housing must remain unobstructed. Its enclosure has an IP65 rating, which helps keep dust and water jets away from internal components. Rotor position is reported through a Hiperface interface, and a resolution of 16 signal periods per revolution supports stable commutation and smooth speed control. The motor uses class 155 insulation, which permits winding temperatures up to 155 °C before insulation aging increases more rapidly. Because the motor is supplied without a holding brake, any load that must remain fixed at standstill needs external braking or drive-applied holding torque.
The encoder connector can be rotated through 240°, which simplifies cable routing in compact machine layouts. The feedback system uses a Multiturn Absolute encoder design, so the drive can retain absolute shaft-turn information after power is removed. The motor has size 075 with an E length code, giving a mid-frame format that fits many servo installations. Winding code 0300 is intended for compatible drive settings across the 0 to 40 °C ambient range used with convection-cooled motors. A plain shaft transfers torque through friction or clamp couplings without keyways, which can help reduce backlash in precision assemblies.
