Product Description:

The MHD093A-058-NG0-AA is a servo motor produced by Bosch Rexroth Indramat within the MHD Synchronous Motors series. It is used for precision motion in industrial automation, where motor size 093 and compact length code A fit standard machine frames. Winding code 058 identifies the electrical layout used with the matching drive, and natural convection cooling removes heat during cyclic duty. The motor is suitable for positioning tasks that require repeatable speed and torque control in automated machinery.

This model supplies a continuous standstill torque of 12.0 Nm, allowing stable axis holding without extra gearing. The enclosure carries a protection rating of IP65, helping keep dust and low-pressure water jets away from internal parts. Alignment during assembly is simplified by a centering diameter of 130 mm, and mounting holes on a flange pattern of 140 / 150 mm match common gearbox adapters. A plain shaft with a factory-installed seal helps limit lubricant escape and contaminant entry. Power is routed through an output connector on side A, which helps with cable routing in compact installations. Digital servo feedback encoders perform optical measurement and provide relative position data to the controller. The motor can operate in ambient temperatures from 0 to 40 °C while using ambient airflow for cooling.

For storage or shipment, the permissible temperature window broadens to -20 to +80 °C, protecting windings and magnets during seasonal changes. Installation is limited to 1000 m above sea level so cooling air density remains predictable. Closed-loop accuracy stays within ± 0.5 angular minutes, which supports synchronized motion in multi-axis equipment. Class F insulation supports internal winding temperatures up to 155 °C. A holding brake is not fitted, so power-off retention must be handled by external mechanics or drive torque.
