Product Description:

The MHD090B-058-NG0-UP is a synchronous servo motor produced by Bosch Rexroth Indramat and belongs to the MHD Synchronous Motors series. It has motor size 090 with B length, and its 110 mm centering diameter helps position the housing accurately on the machine interface. The motor converts drive commands into rotary motion for CNC axes and assembly stations through a plain shaft output. Its optically based feedback system supplies relative position data so the connected drive can maintain coordinated multi-axis motion. This format provides a balanced combination of inertia and thermal capacity for servo-controlled production equipment.

In static loading conditions the motor develops a continuous torque of 12.0 Nm, providing sustained output for holding or slow-speed indexing. The housing has an IP65 rating, which keeps dust and low-pressure water jets away from internal components and the Class F insulation system. Rotor position is tracked with Digital servo feedback (HSF), an incremental encoder format that sends high-resolution signals to the drive. The motor uses a square flange of 140 mm and is intended for ambient temperatures from 0 to 40 °C.

Continuous duty is supported by natural convection, so no external fan is required. The optical sensor achieves a system accuracy of ± 0.5 angular minutes, which supports precise positioning in gantry and pick-and-place modules. Power and feedback connectors are mounted on a header that can rotate through 270° for flexible cable routing, and electromagnetic behavior is set by winding code 058. The motor is supplied without a holding brake, and a shaft seal is fitted to help retain lubricant and limit contamination at the shaft opening. Operation is permitted up to 1000 m above mean sea level, and storage is allowed from −20 to +80 °C when the motor is out of service.
