Product Description:

The MHD093B-058 is an AC synchronous motor from Bosch Rexroth Indramat’s MHD Synchronous Motors series. This unit delivers closed-loop torque and speed to positioning tables, pick-and-place gantries, and other automated machinery when paired with Rexroth digital drives. Acting as the electromechanical interface between the power stage and the load, it converts commanded current into precise rotary motion for industrial automation cells.

At constant excitation the motor can hold a continuous standstill torque of 17.5 Nm, allowing axes to resist static loads without overheating. Accurate mounting is helped by a centering pilot of 130 mm, which aligns the housing to gearboxes or machine frames and limits radial run-out. The square flange offers two bolt patterns—140 mm and 150 mm—so the same unit fits multiple mechanical layouts without adapter plates. These physical interface dimensions, combined with the internal resolver feedback, enable straightforward integration into both new and retrofit installations.

Electrical characteristics are defined by the frame size 093, the length code B, and the winding designation 058. Together, these parameters set the nominal speed, voltage constant, and rotor inertia for drive selection worksheets. The designated product type is a Servo Motor, signaling that the internal magnets and windings are optimized for rapid acceleration rather than continuous duty at line frequency. By combining these catalog codes, engineers can match the motor to existing drives and ensure that cable sets, braking resistors, and fuses meet the required performance margins.
