Product Description:

The MHD115B-058-NP0-AA is a servo motor manufactured by Bosch Rexroth Indramat as part of the MHD Synchronous Motors series. Built for motion control tasks in automated lines, the unit converts drive current into tightly regulated rotary movement for indexing tables, palletizers, and material-handling gantries. Its electromechanical design works with Indramat drive controllers, allowing precise speed regulation and repeatable positioning in multi-axis systems where consistent cycle times are critical. This makes the motor suitable for applications that require frequent acceleration, deceleration, and stable position holding during normal operation.

At the mechanical level, the motor can supply a continuous standstill torque of 50.0 Nm, allowing positioning systems to support load at zero speed without oversizing the drive. Position feedback is generated by Digital servo feedback (HSF), which sends high-resolution incremental data to the controller for tight velocity and position loops. Because the unit is delivered without a holding brake, any static load retention must be handled by the drive controller or an external locking mechanism. Heat is removed through natural convection, so the installation should allow free airflow around the housing. A keyed shaft provides positive engagement with couplings or pulleys, and the shaft seal helps limit dust or fluid ingress.

A frame size of 115 mm and body length B give the motor a medium mechanical envelope for mid-size positioning axes. Power cabling exits on side A, and the mating interface uses an output connector, which keeps wiring direct and compact. The winding code 058 matches the electrical characteristics expected by compatible Rexroth inverters for stable current control. Relative position detection helps the controller identify rotor position quickly after power-up, reducing unnecessary shaft movement before normal motion begins.
