Product Description:
The MHD115B-058-PG1-AA is a servo motor built by Bosch Rexroth Indramat for the MHD Synchronous Motors series. In automated machinery, it converts commanded electrical input into regulated mechanical rotation for coordinated axis movement. When matched with a compatible drive, it supports closed-loop positioning and speed control on packaging, handling, and similar production equipment. This makes it suitable for servo applications that must follow changing commands without losing positional accuracy under varying load. Its operating role suits axes that need steady low-speed response as well as repeatable motion during frequent start-stop cycles.
The motor uses a centering diameter of 180 mm, allowing precise registration with gearboxes or mounting flanges of matching size. At standstill, it can deliver a continuous torque of 50.0 Nm, so it can maintain holding force without thermal overload under rated conditions. Position feedback is obtained through digital servo feedback from an integrated encoder, allowing the drive controller to monitor rotor location with fine resolution. Its square flange measures 192 mm, and this dimension sets the bolt pattern for direct face installation. For vertical axes or controlled stopping, the integrated holding brake supplies 70.0 Nm of torque. The 115 frame size and B motor length suit medium-inertia loads that require stable speed regulation.
Heat created in the stator is removed by natural convection, eliminating the need for external blowers or liquid channels and keeping the motor envelope uncomplicated. Because cooling is passive, the installation does not require separate fan maintenance or coolant plumbing around the motor body. Drive torque is transferred through a plain shaft fitted with a shaft seal, which helps prevent lubricant migration into the housing. The encoder provides absolute feedback over more than 4096 revolutions, reducing the need for homing after a power loss or restart. The winding code 058 indicates the electrical characteristics expected by compatible Rexroth drive converters. Power cabling is routed to side A through an output connector, which can simplify servo wiring inside multi-axis cabinets.
