Product Description:
The MHD093B-058-NG0-AA is a servo motor built by Bosch Rexroth Indramat for the MHD Synchronous Motors series. Classified in the 093 size group, it is used in assembly lines, packaging stations, and handling systems where precise closed-loop rotary motion is required. By pairing permanent magnets with real-time drive electronics, the motor delivers regulated torque and speed so multiple mechanical axes can remain synchronized within automated equipment. This type of motor is well suited to applications that require repeatable acceleration, stable speed control, and accurate positioning over frequent production cycles.
The motor supplies 17.5 Nm of continuous torque at standstill, which is the load it can hold indefinitely without thermal overload. A 130 mm centering diameter keeps the frame concentric to the driven machine and helps reduce vibration. Cooling relies on natural convection, so heat leaves the housing through surface airflow instead of forced fans. Power is transmitted through a plain shaft, allowing clamp or shrink couplings to contact the full diameter. Position data is provided by digital servo feedback (HSF), and the high-speed signals give the drive tight control over velocity and incremental position. Cables are routed through an output connector on side A, and a shaft seal helps prevent oil or coolant from entering the interior windings.
Mounting follows the 140 / 150 mm flange pattern, enabling direct attachment to common gearboxes or machine plates. The unit is delivered without a holding brake, so external locking devices must secure vertical axes during power loss. Motion sequencing uses relative position detection, which means a reference move is necessary after each startup. The electromagnetic characteristics of winding code 058 balance current draw with speed capability, and the B-length frame adds thermal mass that helps the motor absorb short duty peaks during repetitive motion.
