Product Description:

Bosch Rexroth Indramat builds the MSK075C-0300-NN-S2-UG1-RNNN as part of the MSK IndraDyn S Synchronous Motors series. Classified as an IndraDyn S synchronous servomotor, it converts drive current into precisely controlled rotary motion for positioning tables, packaging axes, and other automated equipment on factory floors. Its electromagnetic setup is suited to medium-torque, medium-speed duty within tightly coupled servo loops. A mechanical design with increased concentricity keeps shaft runout low, which supports backlash-free coupling to gearheads or load shafts and helps maintain smooth rotation during repeated motion cycles.

Thermal management relies on natural convection, so the motor can operate without separate fans and can be used where airflow is limited. The aluminum housing has an IP65 rating that keeps out dust and resists water jets during operation. It is rated for ambient temperatures from 0 to 40 °C, and Class 155 insulation allows the windings to handle elevated internal temperatures during cyclic overloads. A plain shaft supports keyed or clamp-coupling connections, while the compact housing helps keep inertia moderate for responsive axis behavior.

Position feedback is handled by an optical encoder with the EnDat 2.1 digital interface for bidirectional parameter exchange with the drive controller. Its scale generates 2048 signal periods per revolution, and the device is a single-turn model, so absolute position is available within one mechanical turn. The encoder connector can be rotated 240° to ease cable routing in tight cabinets and reduce strain at the connection point. For static holding duties, an electrically released brake provides 23 Nm of torque to prevent axis drift when power is off. The brake cavity is sealed against dust and moisture to protect the braking surfaces during normal machine operation.
