Product Description:

The MHD093C-058-NG1-BA is a servo motor manufactured by Bosch Rexroth Indramat as part of the MHD Synchronous Motors series. When paired with a compatible drive controller, it converts commanded current into regulated torque and speed for precise rotary axes in automated packaging, printing, and assembly equipment. Its mid-frame construction provides a balance between payload capacity and installation space, making it suitable for machines that need accurate motion without a large motor envelope. It is well suited for indexing, feed, and transfer tasks that demand consistent response across repeated machine cycles.

This motor develops a continuous stall torque of 23.0 Nm and uses winding code 058 in a C body length within the 093 frame size. Heat is removed by natural convection, allowing installation without external fans. Position data is generated by digital servo feedback (HSF), which uses an optical measuring method and relative position calculation to achieve a system accuracy of ± 0.5 angular minutes. Power and sensor leads exit on side B through an output connector, and the enclosure carries an IP65 rating that protects the stator windings, which use Class F insulation, from dust and water jets. The square flange supports direct mounting to the machine or gearbox. The connector arrangement keeps power and feedback wiring grouped at one end, which can simplify routing in compact machine layouts.

For static loads, the integrated brake delivers 22.0 Nm of holding torque when control voltage is lost. Motion is transferred through a plain shaft aligned by a 130 mm centering diameter and protected by a shaft seal. Rated operation is permitted from 0 to 40 °C, while storage down to -20 °C and elevations up to 1000 m above mean sea level are also allowed. The brake holds the shaft when power is removed, and the shaft seal helps limit contaminants at the output end. These limits fit typical indoor industrial installations and storage conditions found in enclosed automation equipment.
