Product Description:

The MHD115C-058-PG1-RA servo motor is produced by Bosch Rexroth Indramat within the MHD Synchronous Motors series. The unit is intended for closed-loop axis drives in industrial automation, providing position and speed control for gantries, packaging machinery, and general motion platforms. Its integrated digital encoder supplies absolute feedback so the controller knows rotor position immediately after startup. An internal holding brake secures the load when power is removed, which is useful on vertical or suspended axes where drift must be prevented.

At standstill, the motor can deliver 70.0 Nm of continuous torque, allowing it to hold heavy loads without overheating. An IP65 protection rating seals the housing against dust and water jets so it can be mounted outside an enclosure in suitably protected machine areas. The mounting interface uses a 192 mm square flange, giving a predictable bolt pattern for gearboxes or direct-drive couplings. Long-term storage is permissible between -20 to +80 °C, which supports warehousing and transport through changing climate conditions. Heat generated in operation is removed through natural convection, eliminating the need for forced-air or liquid cooling while keeping the thermal design simple.

Mechanical transmission is through a plain shaft, reducing component count when clamping couplings are preferred over keyed hubs. The integrated optical measuring system achieves a system accuracy of ±0.5 angular minutes, which supports tight servo loops in high-precision equipment. The windings use Class F insulation, so the conductors can withstand elevated operating temperatures during cyclic duty. Winding code 058 identifies the electromagnetic layout used for this motor, helping match its electrical behavior to the associated drive controller and power module. This arrangement supports consistent motion response in applications that require stable torque production and accurate positioning over repeated operating cycles.
