Product Description:

The MHP115B-058-HG0-RFNNNN is a synchronous servo motor produced by Bosch Rexroth Indramat for the MHP Synchronous Motors series. Designed for high-response industrial automation axes, the unit converts commanded drive current into rotary torque and position that can be regulated closely by a connected controller. It is suited for closed-loop motion systems that require rapid acceleration, steady speed control, and compact installation in production lines, machine tools, and material-handling equipment, where repeatable motion and predictable axis response are important during continuous operation.

The motor can deliver a continuous standstill torque of 50.0 Nm, giving the axis stable holding force while the shaft remains stationary and energized, which is useful for applications that must resist load movement between commanded position updates. Thermal management is provided by liquid cooling, which helps the stator sustain higher RMS current without early derating during demanding duty cycles. Position information is returned through an incremental encoder with 2048 increments, allowing accurate velocity feedback and commutation support for the drive. The motor uses a plain shaft with a sealing ring for torque transfer, and winding code 058 identifies the electrical characteristics expected by the matching drive controller.

The enclosure has an IP65 rating that helps protect internal parts from dust and water jets, allowing use outside a cabinet when the surrounding conditions are suitable. Operation is intended within an ambient temperature range of 0 to +40 °C, and insulation class F supports winding temperatures associated with demanding intermittent loads. Frame size 115 matches the stator diameter and bolt circle used by compatible gearheads and mounting components. The motor is supplied without a holding brake, and its connections are positioned on the right side to simplify cable routing on layouts that favor that orientation and keep adjacent machine sections clear.
