Product Description:

The MHD093B-058-NG0-BA is a servo motor manufactured by Bosch Rexroth Indramat and assigned to the MHD Synchronous Motors series. In industrial automation, the unit supplies closed-loop rotary motion so that drive controllers can position tooling, conveyors, or pick-and-place arms with repeatable accuracy. This type of motor is used where stable speed control and precise positioning are required during continuous machine operation.

The frame is guided into a machine housing by a centering diameter of 130 mm and attaches on a square flange that spans 140 / 150 mm. Continuous torque at standstill reaches 17.5 Nm, allowing the axis to resist load without motor movement when commanded by the control loop. Heat is dissipated through natural convection, so no auxiliary blower or liquid circuit is used and the installation must allow free ambient airflow. The motor is supplied without a holding brake, which means static load retention must be handled by the servo drive or an external mechanical lock. Motor size 093, length code B, and winding code 058 identify the electromagnetic package used for this unit and match it to compatible Indramat power modules.

Rotor position is returned to the controller by a digital servo feedback (HSF) device that tracks motion incrementally during operation. The motor uses a relative measuring system, so the reference position must be re-established at startup. The steel output shaft uses a plain shaft design and includes a shaft seal to help protect the bearing area from lubricant ingress. Power and feedback cabling exit toward side B through an output connector, which helps with routing when adjacent components limit clearance. This arrangement supports orderly cable placement in compact machine layouts where access around the motor is restricted.
