Product Description:

The MHD115C-035-NP0-BA is a servo motor built by Bosch Rexroth Indramat for the MHD Synchronous Motors series. As a brushless AC drive element, it converts commanded current from a digital drive controller into proportional torque and speed so automated axes can respond accurately during motion. The unit fits applications such as gantry axes, material handling systems, and packaging stations that require coordinated motion within a closed feedback loop during repetitive operation.

This motor’s mechanical envelope supports stable mounting and load transfer. A continuous standstill torque of 70.0 Nm allows it to hold static loads without thermal overload. The square flange measures 192 mm, while the 180 mm centering diameter aligns the stator on the machine plate. The enclosure has an IP65 protection class, preventing dust ingress and water jets in typical factory zones. Operation is permitted from 0 to 40 °C, and installation is allowed up to 1000 m above mean sea level. Size code 115 and length code C indicate the stator stack and overall depth. Power cables terminate on side B through an output connector, and the shaft is fitted with a seal. The design omits a holding brake.

Position feedback is supplied by a digital servo feedback (HSF) encoder that is scanned optically to provide relative rotor angle data with a system accuracy of ± 0.5 angular minutes. The motor is cooled by natural convection, so airflow around the housing must be maintained instead of relying on forced ventilation. A keyed shaft transmits torque directly to couplings while helping prevent slip during reversals. Insulation class F permits winding temperatures up to 155 °C, and storage is allowed between -20 °C and +80 °C when the machine is idle. The package uses a relative position-detection scheme, and winding code 035 matches the drive’s current loop characteristics.
