Product Description:

The MHD115B-058 is a servo motor built by Bosch Rexroth Indramat for the MHD Synchronous Motors series. This rotary unit translates drive-controller commands into precise angular motion and is installed on machinery that needs closed-loop positioning or repeatable cyclic speed, such as pick-and-place stations, presses, and high-throughput packaging lines.

The motor employs size code 115, providing a stator diameter that fits mid-range frames within the series. Alignment to adjoining machine parts is handled by a centering shoulder of 180 mm, minimizing radial run-out during high-speed operation. A square mounting pattern based on a 192 mm flange lets standard bolts secure the housing without adapters. When energized at standstill the shaft can deliver a continuous torque of 50.0 Nm, allowing direct coupling to moderate inertia loads without gear reduction. Electrical behavior is governed by winding code 058; this defines coil resistance, inductance, and the current limits that the matching Indramat drive must supply.

Overall length is set by code B, whose additional rotor stack increases damping and smooths velocity regulation while preserving cabinet depth compatibility. The resulting frame size aids thermal conduction through the stator, keeping temperatures inside an acceptable thermal envelope even during extended duty cycles. Stored inertia and the selected winding combine to provide extra torque reserve, so short acceleration bursts on indexing tables or gantry axes do not push the unit beyond its continuous rating.
