Product Description:

The MHD115B-035-NP0-BA is a servo motor produced by Bosch Rexroth Indramat within the MHD Synchronous Motors series. It drives automated axes that require closed-loop speed and position control in material-handling, packaging, and general motion platforms. Position feedback is generated by a digital servo feedback (HSF) encoder that tracks rotor movement optically and reports relative positions to the drive controller. A keyed shaft transfers torque directly to couplings or pulleys, and a shaft seal protects the bearing cavity from coolant or dust. The motor uses winding code 035, a size 115 frame, and a B-length housing, with a power output connector that exits toward side B of the stator body.

The motor sustains a continuous standstill torque of 50.0 Nm, supplying the holding force demanded by static loads without thermal overload. It mounts to machinery by means of a square flange that measures 192 mm, while concentric alignment is achieved with a 180 mm centering diameter. The enclosure carries an IP65 rating, preventing airborne particles and water jets from entering during wash-down cycles. Reliable function is maintained across an ambient temperature window of 0 to 40 °C, and the keyed output shaft can operate continuously within that range. Because the unit is supplied without a holding brake, any power-off load retention must be provided by external mechanics or by drive torque.

Cooling occurs through natural convection, so no forced-air hardware is required and installation depth stays minimal. When stored, the motor tolerates temperatures from -20 to +80 °C, and it may be mounted up to 1000 m above mean sea level without derating. Class F insulation withstands high winding temperatures, and overall positioning repeatability is held within ± 0.5 angular minutes thanks to the high-speed feedback system.
