Product Description:
The MHD093B-058-NG1-AN belongs to the MHD Synchronous Motors series produced by Bosch Rexroth Indramat. It is a brushless AC servo motor intended for precise axis control in industrial automation systems where feedback-driven positioning and speed regulation are required. It is suited for servo axes that need repeatable starts, stops, and speed changes during automated operation. The motor can be paired with compatible drive electronics for closed-loop motion on packaging, handling, and general automation equipment.
This model delivers a continuous standstill torque of 17.5 Nm, providing stable force for static loads without overheating. Motion is tracked through digital servo feedback in high-speed format, and the rotor position is evaluated optically with relative resolution for accurate control. The integrated brake supplies 22.0 Nm of holding torque, allowing the shaft to resist back-driving when power is removed. A liquid cooling jacket surrounds the stator to transfer heat into an external thermal circuit, so full output can be maintained in tight enclosures. The housing is sealed to IP65, which helps keep dust and water jets away from the internal windings. Positioning repeatability is supported by a system accuracy of ± 0.5 angular minutes. The winding code 058 identifies the electrical constants, and power is routed through an output connector on side A. The plain shaft configuration eliminates keyways, and the high-speed feedback encoder reports relative position data.
Mechanical interface dimensions include a centering diameter of 130 mm and a flange pitch of 140 / 150 mm for direct mounting to gearboxes or machine frames. Class F insulation permits winding temperatures up to 155 °C, while normal operation is specified for ambient temperatures from 0 to 40 °C. Long-term storage is acceptable between -20 °C and 80 °C, and installation heights can reach 1000 m above mean sea level without derating. The motor carries a shaft seal, is identified by size 093 and length code B, and uses relative position detection only.
