Product Description:

The MHD115B-058-NG0-LA is a servo motor produced by Bosch Rexroth Indramat for the MHD Synchronous Motors series. Within an automated cell, the unit transforms regulated three-phase current from a drive into precisely controlled rotational motion. This supports accurate start-stop cycles and stable speed regulation in automated equipment. It is used on indexing tables, gantry axes, and packaging stations that demand repeatable positioning and velocity profiles.

At the rotor, the motor sustains a continuous standstill torque of 50.0 Nm, allowing it to support static mechanical loads while energized without external gearing. Heat generated at that load is removed by natural convection, removing the need for blowers or liquid jackets and simplifying cabinet design. Rotor position is detected with digital servo feedback (HSF), providing the drive with high-resolution incremental data for tight loop control. The output side is built with a plain shaft, so couplings can be mounted directly without keyways or splines that alter concentricity. To minimize lubricant leakage and airborne contamination, a shaft seal surrounds the shaft at the front endplate.

A 180 mm centering diameter aligns the motor accurately in register recesses, and it attaches through a square face with a 192 mm flange size for standardized bolt spacing. Incoming power is routed through a molded connector oriented to the left, which simplifies cable dressing when multiple motors are arranged in tight machine layouts. The motor uses winding code 058, so the selected drive must match this winding to supply the proper voltage, current, and switching frequency. The motor is supplied without a holding brake and uses relative position detection. It is suited to cyclic processes where external clamping devices manage idle-time security.
