Product Description:

The MHD115A-035-PG0-AA is a servo motor produced by Bosch Rexroth Indramat for the MHD Synchronous Motors series. Designed as a permanent-magnet synchronous unit, it links to Rexroth drive controllers and provides closed-loop speed and position control for CNC axes, pick-and-place arms, and other industrial automation modules where repeatable motion is required. Position feedback is furnished by a digital servo encoder whose displacement is measured optically and reported as an absolute value across more than 4096 revolutions.

At standstill, the rotor can continuously deliver 32.0 Nm of torque, giving machines the ability to hold or feed loads without additional gearing. An enclosure rating of IP65 shields the stator against dust and low-pressure water jets, so the motor can be mounted directly on production lines. The mounting interface follows a flange circle of 192 mm with a centering diameter of 180 mm, allowing direct installation within the Rexroth mechanical pattern. Heat generated in the windings is removed by natural convection, so no auxiliary fan or liquid manifold is required. The unit is supplied without a holding brake, which means static load retention must be handled by the drive or an external clamp.

The motor operates reliably between 0 to 40 °C ambient, and it may be stored from -20 to +80 °C without damage. Its windings use Class F insulation to tolerate elevated copper temperatures during high-duty cycles. A feedback chain accuracy of ±0.5 angular minutes supports fine contouring and synchronized multi-axis moves. Size code 115 and length A set the overall body, while installation heights up to 1000 m above mean sea level are permitted. Cables exit toward side A through an output connector that simplifies routing. The rotor employs a plain shaft, and a shaft seal is fitted to prevent coolant or lubricant ingress. Winding code 035 is used with standard Rexroth inverters.
