Product Description:

The MHD115B-058-PP0-LA is a servo motor produced by Bosch Rexroth Indramat for the MHD Synchronous Motors series. It converts drive current into controlled rotary motion for positioning tasks in industrial automation where tight accuracy and repeatable speed are vital. The motor uses a keyed shaft to transmit torque, and a shaft seal helps block contamination at the output end. An integrated encoder supplies absolute position data to the controller, eliminating the need for external sensing hardware.

This model delivers a continuous standstill torque of 50.0 Nm, allowing it to hold heavy loads without overheating. An enclosure rating of IP65 protects internal windings from dust ingress and low-pressure water jets, so the unit can be mounted directly on machinery in washdown areas. Mechanical interface dimensions include a centering diameter of 180 mm and a flange size of 192 mm, which match common ISO motor flange dimensions. Heat is removed through natural convection, so no external blower or liquid circuit is required, and insulation class F permits winding temperatures up to 155 °C. The power lead exits to the left through a sealed power connector, which can simplify cable routing in side-entry installations.

The motor operates in ambient temperatures from 0 to 40 °C and may be stored between -20 °C and 80 °C without damage to the basic mechanical and electrical parts. Closed-loop accuracy reaches ± 0.5 angular minutes because the encoder provides absolute data over more than 4096 revolutions. Electrical characteristics follow winding code 058, and speed feedback is delivered through a digital servo feedback channel that avoids incremental count errors. Operation is intended for installation heights up to 1000 m above mean sea level. The motor has length B and size 115, and it is supplied without a holding brake, so static load retention must come from an external mechanical lock or maintained drive torque during power-off events.
