Product Description:

The MHD115B-024-NG1-RA is a servo motor built by Bosch Rexroth Indramat within the MHD Synchronous Motors series. In automated production, this unit converts drive current from a matching controller into precise rotary motion for positioning, indexing, or speed-regulated transport tasks. Its design targets axes that require high holding capability and accurate feedback without forced ventilation equipment.

During operation, the motor can sustain a continuous standstill torque of 50.0 Nm, and the aluminum housing dissipates the resulting heat through natural convection so no external blower is required. An integrated holding brake delivers 70.0 Nm of static torque to secure vertical or suspended loads when power is removed. The enclosure carries a protection rating of IP65, which blocks dust ingress and water jets, while a shaft seal further guards the plain shaft against splash. Position and velocity information is generated by a digital servo feedback (HSF) encoder that uses an optical measurement method and reports relative positions to the controller. Winding code 024 identifies the electrical characteristics used by the motor, and the design follows the MHD115 size with a right-side power connector.

The mechanical interface presents a centering diameter of 180 mm and a square flange that measures 192 mm, simplifying alignment with gearboxes or machine frames. Insulation is classified as F, supporting winding temperatures suitable for the stated operating range of 0 to 40 °C. Within that range, the feedback chain maintains a system accuracy of ± 0.5 angular minutes, allowing tight contouring on multi-axis gantries. Installation is permitted up to 1000 m above mean sea level, and the unit is specified with motor length code B. When stored out of service, it tolerates temperatures from -20 °C to +80 °C, provided the shaft seal remains lubricated.
