Product Description:

The MHD093C-058-NG0-AA is a servo motor engineered by Bosch Rexroth Indramat for the MHD Synchronous Motors series. With a size 093 frame and length code C, the unit converts drive-controller energy into rotary motion for positioning axes, gantries, and transfer stations. Industrial automation systems use this motor when repeatable torque and accurate speed control are required in compact machinery. Its synchronous design supports precise motion in equipment that runs through frequent positioning and transfer cycles.

The motor provides 23.0 Nm of continuous torque at standstill, allowing sustained load support without excess heating. Mechanical mounting uses a 130 mm centering diameter together with a flange pattern of 140/150 mm, enabling the housing to bolt directly to standard Rexroth faces. Rotor position is monitored through digital servo feedback (HSF), which sends high-resolution incremental data to the drive for closed-loop speed and position correction. Thermal energy is removed by natural convection, so no external blower or liquid circuit is required for moderate duty cycles. Power conductors terminate on side A, which can simplify cable routing when access is limited to one end of the machine.

Torque is transmitted through a plain shaft, and an integrated shaft seal helps protect the front bearing against splash and fine dust. The winding code 058 matches the motor to compatible inverters with the proper voltage constant for this stator. Relative position detection in the encoder means the drive retains reference data once the axis has been homed. Because the motor is supplied without a holding brake, power-off retention must be handled by a mechanical stop or active servo clamping. The connector arrangement keeps the electrical connection compact and supports orderly cable routing.
