I got my hands on two UK sourced blowers - however , the motors are designed for 50Hz. They are also dual voltage.
After doing some research, it appears that raising the frequency, in general, is not a problem with induction motors??? What I did come across though, is that it can be a problem with motors that are designed to reach there hp rating under load - a blower being one of them.
Would changing the voltage to 220V help?
