Hey guys, I’m looking for some help on a setup for spin testing some pumps. I have a 2.2 kw huanyang vfd and spindle motor 220 single ph input. I have got it to work, (Thanks to threads on this site) but I can’t get it to rev over 2000 rpm with the pump connected and no problem when the pump is not in oil. There is an 8+ amp draw at 2000 rpm. The load on the pump shouldn’t be great than 10 ft/lbs or less than 1 HP at 4000 rpm. Below are some of the settings I have now. I’m not sure is 2.2kw isn’t enough or maybe be able to use a gear reduction box, like 2:1 or just need more power. A drill will run it no problem to 800 rpm on an electric drill (Milwaukee) or 1800 +- with a battery drill. PD1= 0 PD2= 1 PD3= 400 PD4= 400 PD5= 400 PD6= 25 PD7= .5 PD8=220 PD9= 55 PD10=8 PD11=20 PD70=0 PD72=200 PD73=20 PD141=220 PD142=11 PD143=4 PD144=3000 Thanks in advanced for any help.
