Product Description:

The MHD093B-058-NG1-AA is a servo motor manufactured by Bosch Rexroth Indramat within the MHD Synchronous Motors series. It is designed for closed-loop speed and position control in industrial automation, where it can couple directly to gearboxes, belts, or driven loads to deliver repeatable rotary motion. The unit combines permanent-magnet excitation, stator windings, and a feedback transducer in one housing. In automated equipment, this type of motor is commonly used on feed axes, transfer units, and indexing assemblies that require repeatable motion over frequent start-stop cycles.

The motor can deliver a continuous standstill torque of 17.5 Nm, giving the axis steady holding capability during static or low-speed operation without excessive heat buildup. A centering diameter of 130 mm aligns the flange on mounting faces and helps keep shaft concentricity consistent during installation. Position information is generated by digital servo feedback (HSF), which supplies high-resolution incremental data to the drive for stable speed regulation and accurate positioning response. The flange spans 140 / 150 mm, matching common mechanical interfaces used on medium-frame machinery. Heat is removed through natural convection, so the motor operates without a separate fan and can be used where simple cooling arrangements are preferred. The feedback signal also helps the connected drive correct load changes quickly during acceleration and deceleration.

The built-in brake provides 22.0 Nm of static torque, helping vertical or suspended axes remain locked when power is removed. A plain shaft supports connection to clamping hubs or shrink discs, and the shaft seal helps limit lubricant migration toward internal motor parts. Power is routed through an output connector on side A, which can simplify cable routing when adjacent mechanical parts limit access at the opposite end. Winding code 058 indicates the electrical resistance and inductance set used with compatible drive controllers. The relative position detection principle allows the control system to establish a reference position at startup without requiring an absolute encoder.
