Product Description:

The MSK075E-0300-FN-S1-AG1-NNBN is an IndraDyn S synchronous servo motor engineered by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It converts regulated drive current into precise rotary motion required for positioning, forming, or conveying axes in automated machines. The 075 frame size and E-length stator stack provide a compact, torque-dense package that fits common machine mounting patterns. In closed-loop systems, the motor works with a compatible drive to deliver repeatable acceleration, speed regulation, and stable holding behavior during indexed or continuous motion. Its compact format is useful where axis spacing, guarding, or nearby process hardware limit the available mounting space.

Heat is removed through liquid cooling, allowing stable thermal control during demanding duty cycles. Position feedback is supplied through the Hiperface serial interface, and the integrated optical scanner resolves 128 signal periods per mechanical revolution. Its optical sensing principle supports accurate feedback, while the single-turn encoder reports absolute shaft position within one revolution. Dynamic stopping is provided by an electrically released brake rated at 23 Nm. The enclosure is rated IP65, which helps protect internal components from dust and water jets, and the power connector is arranged on the A-side to keep cable routing orderly along the machine frame. The combination of feedback and cooling supports precise motion control when the axis must maintain steady thermal behavior over repeated cycles.

The permitted ambient range is 0–40 °C, which matches typical factory operating conditions. A plain shaft supports clamp-style couplings without a key, which can simplify alignment in direct-drive or gearbox-connected assemblies. Because the shaft is plain rather than keyed, torque is typically transferred through friction-locking hubs that preserve concentricity and reduce backlash from loose fits. Insulation class 155 allows high winding temperatures before thermal aging becomes critical. Winding code 0300 identifies the electrical winding used for this motor size. This arrangement suits packaging, handling, and forming axes that run frequent start-stop cycles during normal operation.
