Product Description:
The MHD093A-058-NP2-AA is a servo motor produced by Bosch Rexroth Indramat as part of the MHD Synchronous Motors series. Built on motor size 093 with length code A, this unit uses a keyed shaft for positive mechanical coupling and leaves the factory with a holding brake installed. Power is routed through an output connector on side A of the housing, and relative position information is captured by internal feedback so the drive can maintain commanded motion profiles in automated machinery.
At stall, the motor can deliver a continuous torque of 12.0 Nm, giving machine axes a steady reserve even when movement is paused. A flange pattern of 140 / 150 mm and a centering pilot ensure repeatable alignment to gearboxes or adapters. The housing carries a sealing grade of IP65, so dust and low-pressure water jets will not reach live parts. Position feedback is generated by a digital servo feedback (HSF) encoder that the drive evaluates optically, and winding code 058 matches the electrical constants to standard Indramat inverters. For emergency stops or vertical loads, the integrated brake supplies up to 32.0 Nm of static holding torque.
Thermal energy is removed only by natural convection; therefore, the permitted operating environment must stay between 0 to 40 °C with unrestricted airflow. Storage limits of −20 to +80 °C keep insulation materials within design margins, and Class F varnish withstands higher winding temperatures during duty cycles. The stator face includes a 130 mm centering diameter that cooperates with the chosen flange to minimize runout, while a shaft seal blocks lubricant migration. Combined electronic and mechanical tolerances yield a system accuracy of ± 0.5 angular minutes, and the motor may be installed up to 1000 m above mean sea level without performance derating.
