Product Description:

The MHD115A-058-PG0-AA belongs to the MHD Synchronous Motors series manufactured by Bosch Rexroth Indramat. This servo motor is intended for closed-loop industrial axes where precise rotary motion is required for positioning tasks, packaging equipment, and material-handling stations. By using a rotor sized for the 115 frame class with a plain shaft interface, the device converts drive current into controllable torque that can be scaled by the automation controller. It also supports repeatable motion on axes that cycle frequently during production.

The motor provides a continuous standstill torque of 32.0 Nm, allowing it to hold static loads without thermal overload. The housing carries a protection rating of IP65, so dust ingress and low-pressure water jets do not compromise operation. Class F insulation supports winding temperatures associated with sustained duty cycles, while an operating ambient range of 0 to 40 °C keeps thermal rise within that limit. Heat is removed through natural convection, so no external blower or liquid circuit is required. Digital servo feedback from an integrated absolute encoder with more than 4096 revolutions provides electrical commutation and position data, and the optical measuring method improves resolution stability. The motor is shipped without a holding brake, so mechanical retention must be handled elsewhere if the application requires power-off locking. Power is routed through an output connector on side A, which simplifies cabinet cable routing and service access. A shaft seal is installed to maintain the enclosure rating where the shaft exits the end bell.

Mechanical integration relies on a centering diameter of 180 mm and a square flange that measures 192 mm on each side, matching the bolt pattern commonly used on heavy gantry and transfer systems. The square flange also supports rigid mounting to machine plates and gearbox adapters. System accuracy is rated at ± 0.5 angular minutes. Storage is permitted from -20 to +80 °C, and installation heights may reach 1000 m above mean sea level without derating. The length code A keeps the overall package short, while side-A cabling helps reduce the required machine envelope depth.
