Product Description:

The MHD093B-058-NP2-BA is a servo motor produced by Bosch Rexroth Indramat as part of the MHD Synchronous Motors series. It uses the 093 frame with length B construction and routes its power connection to side B through an output connector. In automated handling and machining stations, the motor converts controlled current from the drive into precise rotary motion for axes that need stable speed regulation and repeatable positioning. This makes it suitable for feed axes, transfer units, and rotary tables where the controller must correct motion errors in real time. Relative optical position detection provides the feedback data needed for closed-loop operation.

At standstill, the rotor can deliver 17.5 Nm of continuous torque, allowing the axis to support a sustained load without overheating. The housing has an IP65 rating, which helps keep dust and low-pressure water jets away from internal components during operation. Shaft position is monitored by a digital servo feedback (HSF) encoder, so the controller can track rotor movement accurately. Heat is removed by natural convection, eliminating the need for an external blower. Because cooling occurs at the motor surface, the installation can remain compact as long as surrounding air can circulate freely around the housing. The motor maintains rated output in ambient temperatures from 0 to 40 °C, and higher temperatures require derating to protect the insulation system.

An electromechanical holding brake provides 32.0 Nm of static torque when the drive is disabled, and it helps prevent unwanted drift on vertical or suspended loads. During closed-loop operation, the motor and feedback system support an accuracy of ± 0.5 angular minutes for applications that require precise indexing. The winding uses F insulation class, and the motor has a keyed shaft for positive torque transmission to pulleys, couplings, or gearboxes. A 130 mm centering diameter and a 140/150 mm flange pattern support accurate mounting on compatible machine interfaces. Installation is permitted up to 1000 m above sea level.
