Product Description:

The MSK040B-0450-NN-S3-UG1-NNNN is a synchronous servomotor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. As a torque and position actuator, it drives axes in packaging lines, pick-and-place gantries, and motion platforms that depend on rapid electrical commutation rather than hydraulic or pneumatic power. This product combines the rotor of an IndraDyn S machine with a compact stator so OEMs can integrate precise closed-loop motion into automation cells without auxiliary gear reduction.

The motor relies on natural convection for heat removal, meaning the housing surface transfers thermal energy to the surrounding air without fans or fluid circuits. Its enclosure carries an IP65 protection rating, so internal windings and bearings are shielded from dust ingress and low-pressure water jets encountered in factory washdowns. A mounted brake supplies 4 Nm of static holding torque; because it is electrically released, the brake secures vertical or suspended loads whenever power is lost. Position feedback travels through the Hiperface interface, allowing the drive to read absolute angle data at startup and during every power cycle. The windings are rated to insulation class 155, permitting continuous operation at elevated temperatures within the motor's thermal limits.

The encoder plug is rotatable through 240°, so the cable exit can be oriented along a machine frame without stressing the leads. Inside the transducer, the capacitive sensor delivers absolute feedback over a single-turn range with 16 signal periods, providing fine resolution within one mechanical revolution. Mechanical integration is simplified by a plain shaft that mates with clamp or collet couplings, and the B-length, size-040 frame keeps mass low for dynamic axes. The motor maintains its stated ratings within an ambient range of 0 to 40 °C, and the 0450 winding code matches current constants to low-voltage IndraDrive amplifiers used in compact multi-axis assemblies.
