Product Description:
The MSK075E-0450-FN-S2-UG2-RNNN is a synchronous servomotor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. It supplies precise torque and position control for industrial axes that need high dynamic accuracy. The unit is equipped with a plain shaft and an electrically released holding brake, making it suitable for direct coupling to gearboxes or load shafts in automated machine tools, packaging lines, and handling modules. Its synchronous motor design lets the paired drive respond quickly to changing command values during positioning and speed-control tasks. This arrangement also supports accurate motion on axes that must start, stop, and hold position repeatedly during normal machine operation.
The stator uses winding code 0450 and is built for forced circulation through liquid cooling, and the FN suffix indicates this cooling method. A 240° rotatable encoder connector simplifies cable routing in compact cabinets, while feedback is transmitted over the EnDat2.1 serial interface. The connector orientation also reduces cable strain where the motor is mounted close to guarding, frames, or adjacent axes. Position resolution is generated through 2048 signal periods from an optical measuring system, enabling tight loop control at the drive. An ingress protection rating of IP65 shields the housing against dust and water jets, so the motor can be installed on exposed machine frames without additional covers. Motor length E provides the active stack height for medium-power axes, and the increased concentricity design helps reduce mechanical runout at the bearing journals.
The electrically released brake supplies 30 Nm of static torque for vertical axes or controlled stops. Internally, the encoder disc uses an optical pickup and supports single-turn position tracking, which suits machines that perform homing after power-up. Operation is specified for ambient conditions from 0–40 °C, assisted by liquid coolant that removes copper and iron losses before they raise winding temperature. This cooling approach supports stable output during repeated acceleration and deceleration. The motor's feedback and brake arrangement also help the drive maintain controlled motion when the axis must pause between indexed moves.
