Product Description:

The MHD093C-058-NG2-BA is a servo motor in the MHD Synchronous Motors series from Bosch Rexroth Indramat. Designed for closed-loop positioning and speed tasks, it converts drive commands into rotation for automated machinery where high repeatability is required. As part of an integrated motion system, the motor couples directly to a machine axis, enabling precise actuation without external gear stages in packaging lines, robotic joints, or printing equipment. This arrangement lets the control system correct speed and position deviations at the motor, which helps maintain smooth motion during indexing and repeat travel cycles.

Mechanically, the unit delivers a continuous standstill torque of 23.0 Nm, giving machines steady holding force during low-speed or static phases. An internal brake rated at 32.0 Nm locks the rotor when power is removed, which is useful on axes that must remain in place at a stop. Mounting uses a centering diameter of 130 mm and a flange interface of 140 / 150 mm. The motor uses a plain shaft with a shaft seal to help limit contaminant entry. Power is routed through a connector on side B, while motion feedback is handled by digital servo feedback (HSF) with optical scanning. The enclosure has an IP65 rating, and the motor has size 093, length code C, and winding code 058.

Thermal behavior is managed by natural convection, so airflow around the housing must be maintained. The stator uses Class F insulation, allowing winding temperatures up to 155 °C. Rated operation is permitted in ambient temperatures from 0 to 40 °C and at installation heights up to 1000 m above sea level, while storage is allowed from -20 to +80 °C when the motor is inactive. System resolution supports positioning repeatability of ± 0.5 angular minutes, and the drive evaluates motion through relative position detection.
