Product Description:

Bosch Rexroth Indramat manufactures the MHD115B-035-PG0-LA, a servo motor from the MHD Synchronous Motors series. This permanently excited AC unit is intended to supply precise rotary motion for packaging, printing, and material-handling axes where closed-loop position and speed control are essential in industrial automation. Its size 115 frame and motor length code B set the physical envelope used by compatible mounting interfaces.

The motor’s winding code 035 sets its electrical constants and works with an integrated digital servo feedback encoder that uses an optical scanning method to deliver absolute position data for more than 4096 revolutions. A centering diameter of 180 mm and a flange size of 192 mm align the frame with heavy gearboxes or machine plates, while the plain shaft transmits torque directly. Continuous output is rated at 50.0 Nm, and the stator cools by natural convection, avoiding external blowers. The power connector is oriented to the left for clean cable routing, and the housing carries a protection rating of IP65 so dust ingress and low-pressure water jets do not interfere with operation. The electrical insulation system uses class F materials, and the motor operates in ambient temperatures from 0 to 40 °C at sea level.

The feedback system supports a system precision of ± 0.5 angular minutes, which benefits fine interpolated moves at low speed. Insulation class F supports winding temperatures expected during repeated acceleration, and a shaft seal helps block lubricant or moisture from entering the bearing chamber. The motor is supplied without a holding brake, so mechanical clamping or drive torque must secure vertical loads during power loss. For storage, it tolerates temperatures from −20 to +80 °C, and installation is permitted up to 1000 m above sea level without a change to the torque or thermal data.
