Product Description:

The MHD093B-058-NP0-AA is a servo motor produced by Bosch Rexroth Indramat within the MHD Synchronous Motors series. Model code 093 indicates the frame size, while winding code 058 identifies the electrical configuration selected for mid-range current demands. The unit serves as a rotary actuator in industrial automation, converting drive output from digital controllers into controlled shaft motion for packaging lines, material-handling axes, and coordinated machine tool feed drives. Its synchronous design supports responsive motion control where accurate speed regulation and repeatable positioning are required. It is suited to applications that require compact servo actuation with direct coupling to the driven mechanism.

As a mechanical component, the motor can deliver a continuous standstill torque of 17.5 Nm, allowing stable force production during precise positioning cycles. The housing carries a protection rating of IP65, so dust ingress and low-pressure water jets do not affect internal windings. Rotor position feedback is generated by a digital servo feedback (HSF) encoder that uses an optical measurement method and reports relative position. Mounting to machine frames is simplified by a flange pattern of 140 / 150 mm and a centering diameter of 130 mm, while motor length code B indicates the stator stack depth. The design omits a holding brake, reducing axial length where sustained static clamping is unnecessary. System accuracy reaches ± 0.5 angular minutes, aided by insulation class F and the optically scanned feedback signals. This feedback arrangement helps the connected drive correct position error during changing loads and short acceleration phases.

Thermal performance relies on natural convection; no external blower or liquid circuit is required, making installation practical at heights up to 1000 m above mean sea level. The motor runs in environments from 0 to 40 °C and can be stored between −20 to +80 °C without degradation. Power enters through an output connector routed to side A, and the shaft interface is a keyed shaft backed by a fitted shaft seal to limit lubricant migration. Connector placement on side A can simplify cable routing where the machine layout keeps power leads on one side of the axis. The feedback signal supports stable control during rapid speed changes and short positioning moves.
