Product Description:
The MHD093C-058-NP0-BA is a servo motor manufactured by Bosch Rexroth Indramat for the MHD Synchronous Motors series. As part of a multi-axis drive system, it receives three-phase power from a Rexroth drive and converts it into rotational torque to move tooling, feed screws, or transfer units under closed-loop control. The unit supports precise velocity and position regulation in automated packaging lines, material-handling gantries, and CNC work cells. Its synchronous design also supports stable motion during frequent acceleration and deceleration cycles.
This model delivers a continuous standstill torque of 23.0 Nm, so the axis can hold static loads without external gearing or brakes. A centering diameter of 130 mm aligns the housing precisely on the machine frame, which helps reduce radial runout during operation. The square mounting flange follows the standard sizes of 140 / 150 mm, which supports common Rexroth and third-party adapter patterns. Position data is returned through Digital servo feedback (HSF), so the drive can monitor rotor movement continuously and correct deviations quickly. Heat generated in the windings is removed by natural convection, allowing operation without auxiliary fans or liquid circuits. This cooling method keeps the overall motor package simple and suitable for enclosed machine layouts with limited space around the axis.
The electrical connection is arranged on side B, which can simplify cable routing when the motor face is difficult to access. A keyed shaft transmits torque directly to couplings or pulleys while helping prevent slippage under reversing loads. The motor reports movement as Relative position data, so the control system references the last homing routine during repeated machine cycles. Internally, the stator uses winding code 058, matched to the voltage and current profile for this 093 frame size. The motor also has a shaft seal to help limit ingress, and motor length C provides a longer housing within this frame size. Because the unit does not include a holding brake, vertical loads require an external method of retention when power is removed.
