Product Description:

The MHD093A-058-PG1-AN is a servo motor configured by Bosch Rexroth Indramat as a member of the MHD Synchronous Motors series. This rotary unit converts electrical energy into controlled mechanical motion for positioning and velocity functions in industrial automation cells and gantries. It couples with matching Indramat drives to furnish precise torque and speed control on packaging lines, handling modules, and processing equipment.

A centering diameter of 130 mm aligns the stator housing to machine frames and maintains concentricity between the motor shaft and driven mechanisms. At standstill, the electromagnetic system can deliver 12.0 Nm continuously, so the axis can support static loads without overheating. Heat produced in the windings is carried away by the integrated liquid cooling jacket, allowing higher power density than air-cooled models. Rotor position and speed are resolved through digital servo feedback from the integrated encoder, enabling closed-loop operation with a single cable. Power enters the unit through an output connector oriented on side A, which can simplify cable routing when the motor is mounted in tight spaces. A shaft seal helps block the ingress of coolant and dust, and the connector style removes the need for a terminal box.

The built-in holding brake clamps the rotor with 22.0 Nm of static torque, preventing motion during power loss or safety stops. Mounting to machinery is handled by a square flange that offers bolt circles of 140 / 150 mm, giving compatibility with several frame patterns. Multi-turn feedback supplies absolute position over more than 4096 revolutions, eliminating the need for homing after each startup. Frame size 093 identifies the motor body size, while the A length keeps overall depth short for axial installations. A plain shaft mates with keyed couplings or shrink discs, and the winding code 058 corresponds to the electrical values expected by compatible Indramat inverters.
