Product Description:

The MHD071B-061-NG0-UN is a synchronous servo motor produced by Bosch Rexroth Indramat for the MHD Synchronous Motors series. In automated systems, this motor converts drive current into tightly regulated rotary motion so that positioning tables, pick-and-place axes, or tool spindles maintain commanded speed and angle under dynamic load changes. This makes it suitable for applications that require repeatable motion and stable response during changing load conditions. The manufacturer designates the electromagnetic stack as length code B, a mid-size configuration that balances inertia with output torque.

The motor mounts to machinery with a centering diameter of 95 mm, which aligns the stator housing concentrically with the driven mechanism. A flange that measures 115 mm provides the standardized bolt pattern for mounting. During continuous stall conditions, it can deliver 8.0 Nm of torque, giving the drive enough holding force for vertical loads or dwell periods without overheating. Heat produced by copper losses is removed through liquid cooling, allowing higher current density and steady operation in confined enclosures. Rotor position is reported by digital servo feedback (HSF), enabling the controller to close torque and velocity loops at high bandwidth for precise contouring.

Cabling can be routed in different cabinet layouts because the power connector is turnable through a range of 270°. This adjustability reduces strain on cable bends and supports flexible installation. Electrical parameters are set by winding code 061, so the mating drive must supply the corresponding voltage and current profile. The built-in feedback system performs relative position detection, which means homing is required after power-up but incremental accuracy remains high during continuous motion. A plain, keyed-free shaft transmits torque through friction couplings or shrink-fit hubs, allowing backlash-free integration into servo gearboxes or direct-drive assemblies without additional mechanical interfaces.
