Product Description:

The MHD115B-035-PP1-BA is a servo motor produced by Bosch Rexroth Indramat within the MHD Synchronous Motors series. Designed for precision positioning in industrial automation, the unit integrates digital servo feedback with an optical absolute encoder that maintains reference for more than 4096 revolutions. That feedback arrangement gives the drive immediate position information after startup and supports accurate motion on indexing, transfer, and packaging axes. A keyed shaft transmits mechanical torque to the load, while a power connector on side B handles electrical connection. Class F insulation supports elevated winding temperatures, and the internal holding brake secures the axis when supply power is removed.

At standstill, the motor can deliver a continuous torque of 50.0 Nm, so it can hold static load without exceeding thermal limits. The cast-aluminum housing is sealed to IP65, protecting the windings and encoder against dust ingress and low-pressure water jets encountered on factory floors. For emergency or power-off conditions, the integrated holding brake applies 70.0 Nm of torque, allowing vertical or suspended axes to remain fixed. Heat generated in operation is removed by natural convection, so no auxiliary blower or liquid circuit is required. Closed-loop positioning repeatability is assisted by a system accuracy of ± 0.5 angular minutes, which supports applications that need tight angular resolution.

The motor uses a square flange that measures 192 mm with a centering pilot of 180 mm, helping align the housing to standard machine interfaces. It belongs to size 115 with the B length code tied to winding pattern 035, and a factory-installed shaft seal helps keep lubricant in place while limiting contaminant entry. Operation is specified from 0 to 40 °C ambient and up to 1000 m above mean sea level without derating. For warehousing or transit, components may be stored between -20 to +80 °C provided condensation is prevented. Dry storage helps protect the bearings, insulation system, and connector surfaces before installation.
