Product Description:

The MHD071B-035-NP0-UN is a brushless servo motor manufactured by Bosch Rexroth Indramat for the MHD Synchronous Motors series. It converts three-phase drive power into precisely regulated rotation for axes in packaging lines, pick-and-place units, and transfer stations. Because the unit operates with electronic commutation and closed-loop feedback, it supports tight position and speed tolerances in industrial automation. This makes it suitable for applications that require stable motion during both indexing and continuous-speed operation.

A centering pilot of 95 mm positions the housing concentrically in the machine bore, while a square flange measuring 115 mm mates with standardized gearboxes and brackets. The stator can sustain 8.0 Nm of continuous standstill torque, giving the controller a predictable force reserve during static holds. Heat produced by copper and iron losses is routed through the jacket by liquid cooling, so the nominal torque can be delivered even when the motor is enclosed. Winding code 035 indicates the conductor size and turn count used for the matched drive inverter. Position feedback is generated by digital servo feedback (HSF), which streams high-resolution incremental data to the controller for rapid current-loop closure.

The combined power and feedback connectors can be swiveled through 270°, allowing cable routing with fewer sharp bends. Motion is referenced by a relative position method, so homing is required after power-up before the absolute axis location is known. The output shaft follows DIN 6885 and uses a keyed shaft to prevent slip between the motor and coupled mechanics. Mechanical length code B marks the second build size within the 071 frame, which balances rotor inertia and thermal mass. A lip seal protects the bearing chamber, and the motor is supplied without a holding brake, so external clamping or drive torque must secure loads whenever power is removed.
