Product Description:
The MHD090B-035-PP0-UN is a servo motor manufactured by Bosch Rexroth Indramat within the MHD Synchronous Motors series. It delivers closed-loop rotary motion for feed axes, gantry drives, and other precision stations in automated lines. The unit is supplied without a holding brake, uses liquid circulation through its housing to manage losses, and relies on an integrated absolute encoder for real-time rotor feedback. Together, these features let the motor maintain positional repeatability while keeping thermal drift low during continuous industrial duty.
The motor can sustain 12.0 Nm of continuous standstill torque, meaning it holds static loads without overheating when commanded to zero speed. Internal passages support liquid cooling, so heat is transferred away from the stator iron rather than into the machine frame, allowing higher torque density in compact spaces. Position and velocity signals are generated by a digital servo feedback device that is built into the rear housing, simplifying wiring and improving diagnostic resolution. Mechanical power is delivered through a Keyed Shaft, giving positive engagement with couplings or pulleys and preventing slippage under reversing loads. A centering pilot of 110 mm aligns the flange with the mounting face, minimizing radial runout and easing replacement during maintenance.
The encoder also provides Absolute (>4096 revolutions) position detection, so multi-turn data is retained after power loss and no homing move is required at startup. Cabling is aided by a connection block that can be rotated through 270°, letting installers orient the power and feedback plugs to match cabinet entry paths. A square flange of 140 mm conforms to standard IEC layouts, while winding code 035 defines the stator resistance and inductance chosen for medium-voltage inverters. Motor length “B,” the presence of a shaft seal, and the dual-connector power interface complete a configuration aimed at high-cycle automation where quick installation and dependable position control are mandatory.
