The Bosch Rexroth R911252185 (MDD090A-N-040-N2L-110GB0) is a high-performance digital AC servomotor that lacks capability for surface cooling via a radial blower. With a nominal speed of 4000min-1 and adherence to DIN VDE 0530 specifications, it is an ideal choice for main spindle applications. The AC servomotor exhibits a dual positioning for both vertical and horizontal installation. It features permanent magnets embedded in a laminated core and bearings lubricated to last a lifetime. The power connector faces the B side and the housing offers protection against high-voltage live or moving parts. It also has an IEC 721-1 compliant longitudinal axis. This servomotor, with a standard pilot diameter of 110mm and length of 275mm, employs electronic commutation for high cyclic load capability. It is fitted with an INS 252 power connector and flaunts a maximum current rating of 41.3A. Other notable characteristics include a flanged socket with 12 pins, optical encoder for relative position detection, and a maximum duty cycle time of 15 minutes.
