Product Description:
The MHD093A-058-PG1-AA is a servo motor manufactured by Bosch Rexroth Indramat within the MHD Synchronous Motors series. It is intended for closed-loop positioning and speed regulation in automated machinery, and its integrated digital servo feedback encoder supplies absolute multi-turn position data directly to the drive controller. The motor has a plain shaft and an output connector on side A, allowing quick electrical and mechanical installation in assembly lines, material-handling axes, or packaging equipment.
The motor can sustain a continuous standstill torque of 12.0 Nm, so it holds loads without overheating when the axis is stationary. A housing protection level of IP65 seals the stator against dust ingress and low-pressure water, eliminating the need for a separate enclosure. A square flange footprint of 140 / 150 mm fits common automation gearboxes, while the 130 mm centering diameter positions the shaft concentrically to minimize radial misalignment. Windings built to insulation class F tolerate internal temperatures up to 155 °C during cyclic duty.
An integrated holding brake delivers 22.0 Nm of static torque, keeping vertical or suspended loads secure whenever the drive is disabled. The frame is cooled by natural convection, so airflow around the housing must be maintained instead of relying on forced ventilation. The motor operates in ambient temperatures from 0 to 40 °C for continuous duty, and it may be stored between −20 °C and +80 °C without damage. System accuracy is ± 0.5 angular minutes, which supports precise repeatability for pick-and-place heads or indexing tables. The motor has a shaft seal to protect internal bearings from coolant or lubricant splash, and installation is permissible up to 1000 m above mean sea level without performance derating.
