Product Description:

The MHD093B-058-PG0-LN is a servo motor manufactured by Bosch Rexroth Indramat and placed within the MHD Synchronous Motors series. As a rotary actuator for industrial automation, the unit converts controlled electrical energy into precise mechanical motion for positioning tasks on packaging lines, handling gantries, and other CNC or assembly stations. Its size 093 frame and B-length housing provide the mechanical envelope required for medium-power axes while remaining compatible with standard Rexroth drive controllers. This motor is suitable for applications that need accurate speed control and repeatable positioning during frequent start-and-stop operation.

The motor has an enclosure protection rating of IP65, which helps keep dust and low-pressure water jets away from the stator frame when the unit is mounted directly on machine tooling. Continuous torque capability is 17.5 Nm at standstill, providing steady rotary force for static holding or low-speed feed moves without overheating. Heat generated at this load is carried to a secondary circuit by the integrated liquid cooling jacket, which improves output density compared with air-cooled designs. A centering pilot of 130 mm aligns the flange within the machine interface for repeatable concentricity. The windings use Class F insulation, allowing elevated internal temperatures before thermal derating is required.

Position accuracy relies on an optical measuring system that delivers a feedback precision of ± 0.5 angular minutes, supporting high-resolution contouring at process speed. The motor is specified for operation between 0 to 40 °C, allowing full rated performance on factory floors where ambient control is limited. For axes that depend on external load-holding devices, the shaft is supplied without a holding brake, which reduces mass and inertia. Absolute position capture extends through over 4096 revolutions, so homing is unnecessary after a power cycle. The left-side power connector can be routed with other drag-chain services when cable space is limited.
