Product Description:

The MHD115A-058-PG1-BA is a servo motor produced by Bosch Rexroth Indramat and supplied within the MHD Synchronous Motors series. As an electromechanical actuator, it converts drive current from a matched controller into precise rotary motion for indexing tables, gantry axes, or packaging stations. Its integrated absolute encoder supports feedback-based positioning, allowing the motor to function as a closed-loop element inside industrial automation cells.

At stall, the motor develops a continuous torque of 32.0 Nm, a level matched to mid-range drive modules for sustained duty cycles. Protection against dust and water jets is IP65, and heat is dissipated by natural convection, so cabinet airflow must carry the losses. Mechanical alignment is simplified by a 180 mm centering diameter and a 192 mm flange that mates directly to gearboxes. The plain steel shaft with a factory seal prevents lubricant egress. Power exits on side B through an output connector, easing cable routing. Internally, class F insulation, winding code 058, and a 115 frame size combine with an optical measurement method to maintain electrical margins during long runs.

For positional security during power loss, the integrated holding brake supplies 70.0 Nm of retentive torque. Position data is returned by digital servo feedback with absolute resolution beyond 4,096 revolutions, enabling repeatability within ±0.5 angular minutes across the full speed range. The motor maintains rated performance at ambient temperatures of 0 to 40 °C and can be installed up to 1,000 m above mean sea level without derating. When idle, components withstand storage temperatures from −20 to 80 °C. All positional information is captured optically, eliminating contact wear. Because the unit is built in length A, total mass and inertia stay compatible with gantries that share the MHD mounting pattern, and the plain output shaft aligns with couplings that do not require a keyway.
