Product Description:
The MHD112B-058-PG1-BN is a servo motor produced by Bosch Rexroth Indramat in the MHD Synchronous Motors series. It is classified as a servo motor and uses motor size 112 with the B length configuration, giving it a compact profile for positioning and speed-controlled axes in automated machinery. In operation, it converts drive commands into controlled rotary motion for handling systems, machine tools, and other industrial equipment. The motor has a plain shaft for direct coupling and includes a holding brake for passive load retention. Its overall layout suits installations where mounting space and cable outlet direction both affect machine design.
At standstill, the motor provides a continuous torque of 28.0 Nm, and heat is removed by liquid cooling rather than forced air. This cooling method helps manage thermal load in enclosed machines where additional airflow is limited. An enclosure rating of IP65 helps protect internal components from dust and water during operation. Accurate mounting is supported by a 130 mm centering diameter and a 192 mm square flange, which fit common machine interfaces. Rotor position is monitored by an integrated digital servo feedback encoder, allowing the drive to maintain precise motion control.
The built-in brake provides 22.0 Nm of static holding torque when the machine is powered down, which is useful on axes that must remain in place at rest. Installation is permitted at elevations up to 1000 m above mean sea level. Closed-loop performance is supported by a system accuracy of ± 0.5 angular minutes, which helps the drive maintain precise positioning. The feedback system is Absolute (>4096 revolutions), so the motor can retain position information through power cycles without a new reference run. The stator windings use insulation class F, the shaft includes a seal for oil-mist environments, and storage is permitted from -20 to +80 °C. Continuous operation must remain within an ambient range of 0 to 40 °C, and winding code 058 identifies the electrical constants used for this model.
