Product Description:

The MHD115A-024-PG1-AA is a servo motor produced by Bosch Rexroth Indramat as part of the MHD Synchronous Motors series. Intended for closed-loop motion axes, the unit translates commanded current into rotary torque for positioning and speed regulation in automated equipment. Its integrated digital encoder supplies absolute position data to the drive, which helps the control system retain accurate axis reference during normal operation. The motor uses a plain shaft for direct coupling to mechanical loads, a side A power connector for straightforward cable routing, and natural convection cooling so no external blower is required.

During continuous standstill, the motor produces 32.0 Nm of torque, enabling static load support without overheating during holding phases. A permanent-magnet brake adds a locking capacity of 70.0 Nm, which helps secure vertical or suspended axes when power is off. The housing has an IP65 rating to help keep out dust and water jets in factory environments. Reliable operation is permitted at ambient temperatures from 0 to 40 °C, supporting stable winding performance and encoder operation. Mechanical centering is provided by a 180 mm pilot diameter that aligns the motor accurately on mounting surfaces and helps reduce radial runout.

The motor uses a 192 mm square flange that mates with standard Rexroth gearboxes. It also uses Class F insulation, allowing short-term winding temperatures up to 155 °C during drive-initiated overloads. Positioning accuracy remains within ± 0.5 angular minutes, and the optical feedback stores an absolute count across >4096 revolutions, which eliminates homing cycles after power is restored. The plain shaft includes a shaft seal to help protect the bearing area from contamination during routine machine operation. Maximum installation altitude is 1000 m, and the motor is commonly used on gantries, transfer units, and general material-handling modules.
