Product Description:

The MHD115B-035-PG0-BN is a servo motor built by Bosch Rexroth Indramat for the MHD Synchronous Motors series. In automated production cells, it converts drive current into precise shaft rotation for packaging, machining, and material-handling stages. The unit belongs to motor size 115 and uses a plain shaft, so torque is transferred through a suitable coupling rather than a keyed output. Position data comes from an optically based digital servo encoder integrated into the housing, and the feedback system provides absolute tracking over more than 4096 revolutions. This arrangement allows the connected drive to retain position information across multiple turns.

A continuous standstill torque of 50.0 Nm allows the motor to hold high-inertia loads at zero speed. Heat is removed by Liquid cooling, which carries thermal energy away from the housing during sustained duty. The housing has an IP65 rating, and a square flange of 192 mm supports mounting to compatible machine interfaces. The permitted ambient operating range is 0 to 40 °C, and closed-loop positioning repeatability is ± 0.5 angular minutes. Insulation class F permits winding temperatures up to 155 °C.

For storage, the ambient temperature can range from -20 to +80 °C when the motor is not in operation. The centering recess measures 180 mm, which helps align the motor with matching machine components. The motor is supplied without a holding brake, so any vertical axis that must remain fixed after power removal needs an external holding device. Power and feedback connections are routed through an output connector on side B, and a shaft seal is fitted at the drive end. The motor uses a B-length housing, can be installed at elevations up to 1000 m above mean sea level, and winding code 035 matches the current data used by the drive controller.
