Product Description:

The MHD115C-035-PP1-BA servo motor is manufactured by Bosch Rexroth Indramat as part of the MHD Synchronous Motors series. It serves as a drive element in automated production cells, converting three-phase electrical power into precisely regulated rotation for gantries, presses, and packaging axes. Digital feedback with an absolute encoder feeds real-time position data to the drive controller, enabling closed-loop speed and angle control under changing mechanical loads.

At standstill, the motor delivers a continuous torque of 70.0 Nm, permitting direct drive of loads without gear reduction. The housing is sealed to IP65, so dust and low-pressure water jets cannot enter the stator cavity. Thermal dissipation relies on natural convection, and fins on the 192 mm square flange promote surface cooling while simplifying alignment to the machine frame. Continuous duty is permitted in ambient temperatures from 0 to 40 °C, and insulation class F materials protect the windings during normal operation. A centering diameter of 180 mm maintains rotor concentricity, and the keyed shaft transfers torque to the driven load. The output connector is oriented to side B, which consolidates the phase and protective-earth conductors, and the C length of the 115 frame fits standard machine envelopes.

Position quality is verified optically through the integrated digital feedback, yielding a system accuracy of ± 0.5 angular minutes. The encoder supplies absolute data for more than 4096 revolutions, removing the need for homing after power-up. A holding brake clamps the shaft when the motor is disabled, and winding code 035 identifies the electrical constants expected by the drive. Safe storage falls between -20 to +80 °C, and a shaft seal helps block lubricant escape. Operation is permitted up to 1000 m above mean sea level, so the motor can be used in elevated facilities. Power leaves through an output connector with strain relief for secure cable routing during installation.
