Product Description:

The MHD115C-058-PP1-AA is a servo motor manufactured by Bosch Rexroth Indramat for the MHD Synchronous Motors series. It drives rotary axes in industrial automation. The motor uses size 115, length code C, and a keyed shaft for direct coupling. Digital servo feedback is integrated in the housing to provide closed-loop velocity and position data to the drive controller.

At the mechanical interface, the unit delivers a 70.0 Nm continuous torque at standstill, helping vertical or high-inertia loads remain stable when motion is paused. The motor is sealed to IP65, keeping dust and low-pressure water out of the windings. Installation is simplified by a 180 mm centering diameter and a 192 mm flange size, which align with standardized mounting patterns. Operation is permitted in ambient air from 0 to 40 °C, and the cast housing dissipates heat by natural convection, so no external blower is required. Power is connected through an output connector on side A to streamline cable routing, a shaft seal helps prevent lubricant migration, and winding code 058 matches the electrical data of Indramat drive amplifiers. The motor can be installed up to 1000 m above mean sea level and stored between −20 and +80 °C.

An internal holding brake supplies 70.0 Nm of static torque, allowing secure position retention when power is removed. The optical measurement method yields a ±0.5 angular-minute system accuracy, supporting precise contouring at the target load. Position data are stored by the feedback electronics as Absolute (>4096 revolutions) position detection, so homing cycles are unnecessary after start-up. Windings built to Class F insulation tolerate up to 155 °C, matching the thermal demands of high-duty cycles. The keyed shaft, output connector, and digital servo feedback encoder support repeatable movement in packaging lines, machining centers, and automated assembly stations.
