Product Description:

The MHD093A-058-PG0-LA is a servo motor produced by Bosch Rexroth Indramat for use in closed-loop motion axes inside automated machinery. It belongs to the MHD Synchronous Motors series and combines an integrated optical encoder with digital servo feedback so the drive controller can monitor rotor position without external sensors. The model’s plain shaft couples directly to gearboxes or belt pulleys, allowing the motor to convert electrical energy into rotational motion for positioning and speed-regulated tasks. This arrangement keeps the motor and feedback package compact for machinery that needs precise, repeatable axis movement.

A centering shoulder of 130 mm aligns the housing on the mounting face, while the square flange is drilled on the 140 / 150 mm bolt circle used for IEC mounting. When the rotor is energized but stationary, the motor can supply 12.0 Nm of continuous torque, which provides a reference point for static load calculations. Thermal design relies on natural convection through the ribbed aluminum frame, and the windings use winding code 058 to match compatible Indramat drives. The housing has an IP65 protection rating, which helps keep airborne dust and low-pressure water jets out of the interior during washdown or machining operations.

The integrated optical sensor provides absolute feedback over more than 4096 revolutions, giving a system resolution of ± 0.5 angular minutes for repeatable positioning. Within the operating range of 0 to 40 °C, Class F insulation maintains dielectric strength and helps protect the windings during normal use. Because the construction omits a holding brake, the application must use external locking or continuous drive torque to keep the axis stationary when power is removed. A shaft seal helps limit lubricant migration, and the left-side power connector can simplify cable routing in cabinets installed up to 1000 m above sea level.
