Product Description:
The MHD093B-058-PP1-AA is a servo-class rotary actuator produced by Bosch Rexroth Indramat and belongs to the MHD Synchronous Motors series. This model is a servo motor intended to deliver closed-loop motion in industrial automation axes that rely on permanent-magnet synchronous technology. Its role is to convert drive current from an inverter into controlled shaft torque and position, supporting machinery that demands repeatable velocity profiles and high-resolution feedback.
The motor mounts through a centering diameter of 130 mm, aligning the 093 frame with mechanical reference faces. A flange size of 140 / 150 mm provides the bolt circle needed for standard machine plates, while the B length code indicates the stack depth without altering shaft height. At standstill, it can supply 17.5 Nm of continuous torque, enabling static holding or low-speed duty without overheating. Heat is removed by natural convection, so airflow around the housing must be ensured instead of relying on forced cooling devices. Power is routed through an output connector on side A, simplifying cabinet cable runs and maintaining separation between power and feedback lines. Digital servo feedback with an integrated encoder transmits position data to the drive for synchronous commutation.
The motor also includes several mechanical and safety features for controlled operation. A holding brake rated at 22.0 Nm engages automatically when power is removed, securing vertical or suspended loads. The transmission interface is a keyed shaft, and a shaft seal is fitted to block lubricant spray and particulate ingress at the coupling point. Absolute position detection surpasses 4096 revolutions, giving the controller a stable multi-turn reference after each power cycle. The electromagnetic system uses winding code 058, allowing pairing with drives tuned for the associated resistance and inductance values. This combination supports axes that must hold position when power is removed and resume operation with retained position information.
