Product Description:
The MHD115B-058-PG0-AA is a three-phase servo motor manufactured by Bosch Rexroth Indramat and included in the MHD Synchronous Motors series. Classified as a servo motor, it converts drive current into tightly regulated mechanical motion for positioning axes in machine tools and automated handling equipment. The winding code 058 identifies the stator configuration, while the plain shaft output is intended for couplings that already contain their own locking elements.
This unit is built on motor size 115 with length code B, and its mounting interface is a 192 mm square flange that centers on a 180 mm diameter pilot. At standstill, it can produce 50.0 Nm of continuous torque, allowing high holding force without active cooling. The aluminum housing reaches a protection class of IP65, so the internal windings remain isolated from dust and water jets. Heat is removed only by natural convection, so auxiliary fans are unnecessary in cabinets where airflow is restricted. Class F insulation tolerates winding temperatures up to 155 °C, and the power leads exit on side A through an output connector that supports straightforward cable routing.
Position feedback is handled by a digital servo encoder that relies on an optical measurement method to reach a system accuracy of ± 0.5 angular minutes. The transducer delivers absolute information for each revolution and keeps track of more than 4096 revolutions without battery support. During operation, the motor complies with an ambient range of 0 to 40 °C, while storage and transport are permitted from -20 to +80 °C. A shaft seal is fitted to protect the bearings, yet the design is supplied without a holding brake, so external mechanical restraints must be used when power is removed. The motor can be installed up to 1000 m above mean sea level without derating, maintaining full performance under natural-convection cooling.
