Product Description:

The MHD090B-035-NP1-UN is a servo motor manufactured by Bosch Rexroth Indramat for the MHD Synchronous Motors series. In automated machinery, this kind of motor provides controlled rotary motion that can be synchronized with drive commands, allowing precise positioning and repeatable speed profiles on packaging lines, gantry axes, and transfer stations. Its synchronous design supports accurate response during indexing, speed regulation, and coordinated multi-axis movement. This allows the motor to serve both continuous-process motion and repeated point-to-point moves in the same machine layout.

The unit mounts to a machine wall through a centering pilot of 110 mm and a square flange that measures 140 mm. These interface sizes locate the stator coaxially to downstream mechanics and help prevent radial misalignment during installation. During static holding or very low-speed moves, the electromagnetic stack can supply 12.0 Nm of continuous standstill torque, providing support for medium-inertia loads without overheating. Feedback is delivered by digital servo feedback (HSF), which streams high-resolution incremental data to the drive for tight current and velocity regulation. Heat generated in the windings is removed by liquid cooling, so the motor can remain within its insulation class even inside sealed cabinets or high-ambient areas.

An integrated brake produces 11.0 Nm of holding torque to secure vertical axes when the supply is removed, while rotor length code B balances inertia against overall mass for responsive acceleration. The power connector is turnable through a range of 270°, which helps with cable routing in confined spaces, and the separate feedback plug shares the same housing. A keyed shaft, reinforced by an external shaft seal, transmits torque without slip and helps block fluid ingress. Additional details include motor size 090, winding code 035, relative position detection, and the use of combined power and feedback connectors for compatible Rexroth drive systems.
