Morning All,
I currently have a project that controls a 1hp motor from a frequency inverter operating from filtered mains input. The inverter "agitates" the motors at 30Hz, 35Hz, 40Hz and 50Hz.
With the inverter moved away from the motor assembly all works fine, however, when moved back into close proximity, all goes loopy, it seems to me that the pulses from the motors at start-up / operation are so heavy that they "knockout" the inverter function.
The inverter is digital, and I have tried to re-programme start up, lead,lag stall ect, but as mentioned all is ok when the inverter is moved away.
(the output from the inverter is directly wired to the motor assy, and a magnetic core assy is currently wrapped around the wire assy)
Any ideas very greatly appreciated...........desperate !!!
Many thanks to all
