Product Description:
The MHD090B-058-NG0-UN is a synchronous servo motor built by Bosch Rexroth Indramat for the MHD Synchronous Motors series. Used as a drive element in automation axes, it converts commanded current into precise torque and speed for machining centers, material‐handling gantries, and packaging equipment where repeatable positioning is critical.
This model develops a continuous standstill torque of 12.0 Nm, supplying stable holding or low-speed motion without overheating. Its centering diameter of 110 mm matches standard mounting pilots so the motor seats accurately on the machine frame, while a flange dimension of 140 mm provides the bolt circle needed for rigid installation. Heat is removed through liquid cooling, allowing higher current density than air-cooled equivalents. Position data come from a digital servo feedback (HSF) encoder that streams high-resolution signals to the drive. For simplified wiring, the power connector can be rotated within 270° so the cable exits align with cabinet layouts.
The mechanical interface uses a plain shaft that couples with keyed or clamped hubs without extra machining. Winding code 058 defines the electrical resistance and inductance set that pairs with Rexroth inverters for rated current delivery. Motion control relies on relative feedback; the detector reports incremental counts identified as Relative position, and absolute home is established during system referencing. Additional details include the motor size 090 frame and the B-length stator, a power and feedback connector set on the housing, and the ability to swivel those connectors for service access. Together, these specifications align the motor with medium-inertia loads that demand liquid-cooled continuous torque and flexible cabling in confined machine envelopes.
