Product Description:

The MHD115A-058-NP0-BN is a servo motor built by Bosch Rexroth Indramat for the MHD Synchronous Motors series. As a drive element, it converts regulated electrical power into precise rotary movement for coordinated positioning and speed control on packaging, material-handling, and machining axes within industrial automation. The unit is supplied without a holding brake, so static retention must be handled by external mechanical locks or commanded drive torque. Its electrical and mechanical features are suited to digital controllers that require high feedback resolution and repeatable torque delivery during continuous machine cycles. It is suitable for applications that need stable low-speed control as well as accurate point-to-point positioning.

Its standstill capability is rated at 32.0 Nm, giving the axis substantial static torque at zero speed. The housing is rated IP65 to help keep out dust and water spray, while liquid cooling circulates through the stator jacket to remove heat during continuous duty. Rotor position is monitored through Digital servo feedback (HSF), so the controller receives incremental feedback for closed-loop motion control. A 192 mm square flange matches the 115 frame size for standard machine interfaces. The motor also uses winding code 058, insulation class F, an optical measurement method, and relative position detection.

The mounting pilot measures 180 mm, providing concentric alignment between the motor and the driven load. Torque is transmitted through a keyed shaft with an integral shaft seal. Closed-loop accuracy reaches ± 0.5 angular minutes. Ambient operation is allowed from 0 to 40 °C, and storage is permitted from -20 to +80 °C without damage to internal materials. The design supports installation up to 1000 m above mean sea level without derating, while motor length A and the side B connector orientation help keep the package compact and simplify cable routing.
