Product Description:

The MHD115B-035-PG0-AA is a servo motor produced by Bosch Rexroth Indramat for the MHD Synchronous Motors series. It serves as the primary rotary actuator on CNC workstations, packaging lines, and material-handling axes, converting drive power from an Indramat inverter into tightly regulated motion. Digital feedback embedded in the motor allows the controller to read absolute rotor position in real time and synchronize complex machine sequences. This arrangement supports accurate indexing and repeatable speed control in machines that must coordinate motion across multiple driven axes.

The motor uses winding code 035, which balances current demand with thermal limits for this frame. At standstill, it delivers a continuous torque of 50.0 Nm, allowing heavy loads to be held without excessive torque ripple. Heat is removed through natural convection, so no external blower or liquid circuit is necessary as long as the ambient temperature remains within 0 to 40 °C. The sealed housing carries a rating of IP65, which helps block dust ingress and water jets during normal industrial use. Position data comes from a digital servo feedback device that uses an optical measuring method and achieves a system accuracy of ± 0.5 angular minutes while tracking absolute position over more than 4096 revolutions. A shaft seal is fitted, and the motor is supplied without a holding brake.

Mechanical interfaces follow IEC dimensions: the centering pilot is 180 mm and the square flange is 192 mm. These dimensions correspond to motor size 115 with motor length B and support alignment on compatible machine flanges. A plain shaft transmits torque directly, and power conductors exit on side A through an output connector that helps keep cable routing orderly in enclosed machine layouts. Installation is permitted at elevations up to 1000 m above mean sea level, and the F-class insulation system resists thermal stress during normal servo duty. When de-energized, the motor may be stored between -20 to +80 °C without degrading the optical encoder or shaft seal.
