Product Description:
The MHD090B-047-NG0-UN is a brushless AC servo motor produced by Bosch Rexroth Indramat and assigned to the MHD Synchronous Motors series. Designed for closed-loop drive systems, the unit converts electrical power to controlled mechanical rotation for positioning and velocity tasks on automated machinery. Its winding code 047, frame length B, and size 090 place it in the mid-torque segment of the series, making it suitable for moderate-load axes such as packaging heads, gantry carriages, and material handling stations.
At standstill, the motor can deliver a continuous torque of 12.0 Nm, giving machinery enough holding force for static loads without overheating. Heat generated during duty cycles is carried away by its liquid cooling jacket, which keeps winding temperatures within Class F limits and supports high cycling rates. The housing satisfies the IP65 protection level, so dust ingress and low-pressure water jets do not disturb internal components. Mechanical interfacing is standardized; a flange diameter of 140 mm sets the bolt circle while a centering pilot of 110 mm aligns the shaft concentrically to attached gearboxes or belt pulleys.
The digital servo feedback encoder resolves rotor position optically and contributes to a system accuracy of ± 0.5 angular minutes, which fits axes that demand fine repeatability. During operation, the motor may run in ambient temperatures of 0 to 40 °C, and the design maintains thermal stability at altitudes up to 1000 m above mean sea level. For electrical integration, the power and feedback connectors can be rotated through 270°, easing cable routing inside tight cabinets. When machines are idle or in transit, the winding set withstands storage temperatures from -20 to +80 °C, and a shaft seal prevents lubricant escape under these conditions.
