Product Description:
The MHD095B-035-PG1-RN servo motor is manufactured by Bosch Rexroth Indramat within the MHD Synchronous Motors series. It serves as the electromechanical drive element on numerically controlled axes, converting regulated current from the drive into torque and speed that can be commanded precisely by the automation controller. This arrangement supports repeatable motion on packaging stations, gantry systems, and transfer modules where accurate acceleration, deceleration, and holding behavior are required. Its combination of motor design, feedback hardware, and cooling method allows stable operation during continuous-duty machine cycles.
The mechanical interface covers mounting dimensions and torque capability. A centering diameter of 130 mm aligns the housing concentrically to the machine frame, while the square flange measures 140 / 150 mm to match common motor adapters in this size class. The size 095 frame with length code B gives the motor a compact profile while still supporting a continuous standstill torque of 17.5 Nm. Heat is removed by liquid cooling, which helps the motor maintain output in confined installations where ambient air circulation is limited. The rotor uses a plain shaft, and a shaft seal helps keep lubricant or ambient moisture away from the internal bearings. Electrical power is supplied through a fixed connector that locks to the housing, and the winding group uses the internal designation 035.
The feedback and holding functions are arranged for closed-loop axis control. A digital servo feedback with an integrated encoder sends single-turn and multi-turn position data to the drive, allowing the controller to track rotor angle continuously during motion. Absolute position information covers more than 4096 revolutions, so the axis can retain position reference after power interruptions without a homing cycle. A built-in holding brake rated at 22.0 Nm secures vertical or suspended axes at zero speed when the drive is not actively producing torque. The brake and encoder signals are routed alongside the three-phase supply because the power connector is positioned to the right of the shaft, which helps keep cable routing consistent at the motor end.
