Product Description:

The MHD115B-058-NG0-AA is a servo motor manufactured by Bosch Rexroth Indramat and belongs to the MHD Synchronous Motors series. Intended for industrial automation, this motor converts drive commands from a compatible controller into precise mechanical rotation for positioning or speed-regulated axes. The 115 frame size together with winding code 058 provides a mid-range torque profile while keeping inertia moderate, making it suitable for packaging, metal-cutting, and material-handling equipment that demands repeatable motion. It is typically used in closed-loop systems where stable torque delivery and consistent positioning are needed during frequent starts, stops, and speed changes.

With a continuous standstill torque of 50.0 Nm, the motor can hold loads without overheating when the rotor is locked. A flange diameter of 192 mm pairs with a centering diameter of 180 mm to support accurate mounting on machine plates and gear interfaces. The plain shaft includes a seal to help keep contaminants away from internal bearing areas, and the enclosure meets the IP65 rating for dust-tightness and protection against water jets. No holding brake is fitted, so external clamping may be needed for power-off retention. Position feedback is supplied by digital servo feedback with optical scanning, and the system reports relative position with an accuracy of ± 0.5 angular minutes.

Thermal limits allow operation between 0 to 40 °C, while the unit may be stored from -20 to +80 °C without degrading insulation. Heat produced in the stator is removed by natural convection, which eliminates the need for separate fans or liquid cooling hardware. This cooling method, together with Class F winding insulation, supports continuous duty at altitudes up to 1000 m above mean sea level. Power is routed through an output connector on side A, and motor length code B helps keep the installation depth practical for machines with limited axial space.
