Dimensions of mounting and Outline

-
Note:
- The drawing is B35 type. There have housing feet and flange on end shield.
- B3 type motors have frame feet but no flange, the dimensions have no M、N、P、R、S、T。
- B5 type motors have flange but no frame feet, the dimensions have no A、B、C、AB。
- There are eight symmetrical distributed holes for flange mounting on the FS225~ 355 motors.
- R is the distance from the flange to the drive shaft end.
