The five most commonly used mounting methods are :
- B3 : Foot only
- B5 : Outer flange (flange diameter exceeds that of the motor)
- B14 : Inner flange (flange diameter is smaller than that of the motor)
- B35 : Foot mounted + outer flange (combination of B3 and B5)
- B34 : Foot mounted + inner flange (combination of B3 and B14)
