Product Description:

The MHD071B-035-PG3-UN is a servo motor built by Bosch Rexroth Indramat as part of the MHD Synchronous Motors series. It converts controlled three-phase drive currents into precise rotary motion for positioning tables, handling modules, and packaging axes. A liquid-cooled housing and integrated digital feedback let this 071-frame unit deliver continuous torque while maintaining tight speed regulation in automated production lines. An IEC 115 mm flange and a rotating power connector support flexible installation across diverse machine platforms.

The mechanical interface begins with a 95 mm centering diameter that aligns the stator barrel on the machine plate. The motor can exert 8.0 Nm of continuous standstill torque, allowing the axis to resist load without overheating. Cooling is handled by a liquid-cooling jacket wrapped around the stator, so thermal energy is carried away by circulating fluid instead of ambient air. Motion feedback comes from digital servo feedback with an integrated encoder, giving the drive accurate rotor position data for tight velocity control. Attachment holes follow a 115 mm square flange, allowing the motor to fit standard IEC-size mounting patterns without adapter rings.

A fail-safe brake supplies 10.0 Nm of static torque, locking the rotor during emergencies or when power is off. The power connector is turnable through a range of 270°, allowing cables to exit in the most convenient direction. Torque is transmitted through a plain shaft, which eliminates keyway stress and eases coupling alignment. The encoder offers absolute position tracking over more than 4096 revolutions, so the axis can retain position information immediately after startup. The motor also includes a shaft seal, winding code 035, motor length B, and combined power and feedback connectors for compact fluid-cooled machine layouts with clean cable routing.
