Product Description:

The MHD093B-058-NG1-BA servo motor is produced by Bosch Rexroth Indramat for the MHD Synchronous Motors series. It converts controlled electrical energy into rotary motion so that machine axes, conveyors, and tooling stations can be positioned quickly and accurately within industrial automation cells. The motor is intended for closed-loop servo applications that require steady torque delivery and repeatable motion under changing loads. Its synchronous design also supports responsive acceleration and consistent speed control in packaging, handling, and general production equipment.

At the mechanical interface, the motor delivers a continuous standstill torque of 17.5 Nm, allowing it to hold loads without overheating during static duties. Alignment with gearboxes or mounting plates is guided by a centering diameter of 130 mm, which helps locate the motor accurately on the pilot fit. Rotor angle and speed data are provided by digital servo feedback (HSF), and this high-speed format supports tight current loops in Indramat drive controllers. Power is routed through an industrial output connector, and the cables exit the housing on side B so routing can be kept clear in fixed machine layouts. The motor also uses relative position detection, and it includes a shaft seal that helps block coolant or oil ingress.

The square flange follows a span of 140 / 150 mm, which suits standard Rexroth mounting grids. A built-in holding brake applies 22.0 Nm of static torque to secure vertical or indexed axes when power is removed. Heat from copper losses is dissipated by natural convection, so no external blower or liquid circuit is required. The smooth, plain shaft minimizes runout when coupled through friction hubs or collets and avoids keyway stress concentrations. This shaft arrangement works well with clamping couplings that require a smooth contact surface.
