Product Description:

The MHD115A-058-NP1-BA is a servo motor engineered by Bosch Rexroth Indramat within the MHD Synchronous Motors series. It drives rotary axes in automated lines, combining an internal encoder with a keyed shaft to give motion controllers direct position data and a secure mechanical interface. This arrangement supports closed-loop speed and torque control in packaging, material-handling, and machining equipment. The motor is intended for servo systems that require controlled acceleration and stable holding behavior. In many automated machines, it can serve in place of pneumatic or hydraulic actuators where precise rotary motion is required.

Its stall capability is 32.0 Nm, permitting the motor to hold or accelerate loads from standstill without overheating. Positional data come from digital servo feedback (HSF), which is read optically and uses relative measurement with a system accuracy of ±0.5 angular minutes. A centering diameter of 180 mm mates with a 192 mm square flange, and the keyed shaft suits standard couplings for direct power transfer. The winding code 058 and motor length A correspond to size 115, so the electrical values match compatible MHD-class inverters. Cooling is provided by natural convection, and the housing is sealed to IP65. Internal windings use insulation class F for thermal endurance in industrial duty. Power enters through a connector on side B, which helps reduce cable stress during installation.

For power-off safety, the integrated holding brake provides 70.0 Nm of torque, and a shaft seal helps keep dust away from the keyed interface. Reliable operation is permitted from 0 to 40 °C, while storage and shipment are allowed from -20 to +80 °C without harming the magnets or resin. The motor may be installed up to 1000 m above mean sea level while remaining within its intended installation range.
