Product Description:
The MHD112B-058-PG0-RN is a three-phase AC servo motor built by Bosch Rexroth Indramat and supplied within the MHD Synchronous Motors series. Designed for closed-loop positioning systems, the unit converts drive commands into precise rotary motion for gantries, packaging lines, and tool spindles. Its integrated absolute encoder provides multi-turn feedback so the controller can maintain target positions after power cycles and during dynamic load changes. This arrangement also lets the drive monitor position continuously without requiring a separate external feedback device at the axis.
It delivers a continuous standstill torque of 28.0 Nm, allowing the axis to hold load without extra gearing while minimizing current draw. The housing carries a protection rating of IP65, which helps keep dust and water jets away from internal components. Heat generated by copper losses is removed through liquid cooling, which supports demanding duty cycles and steady thermal control during extended operation. For storage, the motor tolerates temperatures from -20 to +80 °C, and during operation it may run between 0 and 40 °C at mounting heights up to 1000 m above mean sea level. Position error is limited to ± 0.5 angular minutes through its optical measurement method and digital servo feedback. Because the motor is supplied without a holding brake, the load must be secured by mechanical locking or drive-applied torque when power is off.
Mechanical interfaces follow standard IEC-style mounting dimensions for straightforward machine integration. The centering pilot is 130 mm, and the flange spans 192 mm, giving the mounting face good rigidity for couplings that apply side load. A plain shaft with a factory-installed seal supports power transmission while helping limit contamination entry and lubricant escape. Power enters through a right-handed connector, and the feedback wiring stays on the opposite side to reduce crosstalk between power and signal paths. Class F insulation permits winding temperatures up to 155 °C. The B-length stator, 112 frame size, and 058 winding code are matched to the intended speed-torque range of this motor.
