Product Description:
The MHD115A-058-PG1-AA is a servo motor manufactured by Bosch Rexroth Indramat and assigned to the MHD Synchronous Motors series. Designed for tightly controlled industrial axes, the motor combines integrated digital servo feedback with an absolute encoder so a drive controller can monitor shaft position over more than 4,096 revolutions without using external sensors. Its design simplifies line-side wiring when the motor is installed in packaging, printing, and material-handling equipment. This feedback arrangement supports stable positioning during repeated motion and after power cycling.
At standstill, the motor can exert 32.0 Nm of continuous torque, which represents the constant load it may hold without exceeding thermal limits. The housing carries an IP65 rating, blocking dust ingress and low-pressure water jets so separate enclosure panels are unnecessary in many installations. A 192 mm square mounting flange aligns with a 180 mm centering diameter, giving a repeatable reference surface for gearboxes or machine frames. Heat created by copper losses leaves the stator through natural convection, eliminating the need for external blowers. Winding code 058, motor length A, and size 115 establish the motor's electrical and geometric format, while the power leads exit on side A through an output connector. A shaft seal is fitted to limit lubricant escape and help keep contaminants away from the bearing area.
Dynamic holding tasks are supported by an integrated brake that clamps the rotor with 70.0 Nm of torque when power is removed. Position feedback is measured optically, and the closed-loop system delivers ± 0.5 angular minutes of system accuracy for repeatable indexing. Class F insulation allows the windings to reach elevated temperatures while remaining reliable within an operating envelope of 0 to 40 °C. When the machine is idle, the motor may be stored between -20 to +80 °C without damage. A plain shaft and a maximum installation height of 1,000 m above mean sea level broaden application options in automated assembly lines.
