Product Description:
The MHD115C-058-NG0-BN is a servo motor manufactured by Bosch Rexroth Indramat and delivered as part of the MHD Synchronous Motors series. It serves as a drive element in automated machinery, converting regulated three-phase input into tightly controlled rotary motion for positioning axes, gantry systems, and material-handling stations. When used with digital drive controllers, the motor supplies consistent torque and speed so that production lines can maintain cycle accuracy under changing mechanical loads.
This model supplies a continuous standstill torque of 70.0 Nm, enabling it to hold sizable loads without drift while energized. Heat generated during high-current duty is removed by liquid cooling through the housing jacket, preserving winding life and limiting thermal expansion. The housing is rated IP65, sealing the stator against dust ingress and water jets, and a shaft seal protects the bearings. Precise mounting is assisted by a 180 mm centering diameter, and the square mounting interface measures 192 mm across the flange. Power conductors exit on side B through an output connector, which can simplify cabinet routing in fixed machine layouts. Encoder feedback is provided by digital servo feedback, and the optical position system uses fine index marks for repeatable resolution.
The motor operates in ambient temperatures from 0 to 40 °C, while Class F insulation permits internal hot-spot temperatures up to 155 °C. A plain shaft simplifies coupling to gearboxes or pulleys, and overall positioning accuracy is held within ± 0.5 angular minutes. Installation is allowed up to 1000 m above mean sea level, and storage conditions span -20 to +80 °C. Because the unit is supplied without a holding brake, external locking must provide power-off retention. Motor length code C and size 115 establish the magnetic stack dimensions, while winding code 058 identifies the electrical resistance and inductance used for drive tuning. Relative position detection resets the reference at power-up, which suits machines that home at startup.
