R911320786
The R911320786 (MHD112B-058-NG0-RN), a product of Bosch Rexroth Indramat, is a synchronous motor designed with an integrated encoder system for digital servo feedback. Its brushless design eliminates the need for maintenance, while the grease-lubricated bearings reduce friction for smooth operation throughout its service life. In terms of dimensions, it has a flange size of 260mm, a centering diameter of 250mm, and four pole pairs. Installed into industrial machinery, its role is to feed current motor position data to the associated drive controller for precise positioning and speed control.
Installation limitations include a maximum height of 1000m above sea level, and avoidance of fluid accumulation when installed vertically with the shaft upward. The motor boasts of low inertia, thanks to the permanent magnets made from special materials. Its shaft and bearings deal with radial and axial forces during operation. A unique feature is the data memory in the motor's encoder that stores the motor type name and parameters, alongside the control loop parameters. Finally, it is classified as length code B, and an IP 65 degree of protection is guaranteed when power and encoder cables are correctly fitted. Its theoretical maximum torque stands at 102Nm. Despite a peak current rating of 183A, the motor can be shipped to any global location.
