We used the vacuum cleaner motor 2200W 220v in one dental device (vacuum former) as you can see here:
So now one of our costumers said when they used this device the power cable is warmed and when the vacuum motor started the dental clinic circuit breaker (25A C type fuses) trip (could be seen here:)
and disconnect the power of the whole system, so I guess it using 10A for steady-state but I don't know how much current this motor get for startup and could this situation be the result of this trips.
Based this site:
Vpeak = IinR, where Vpeak = √2(V)
and
E = CV2/2
So we have 220v : √2*220/15=20.74 A
I found this vacuum cleaner’s current waveform from here: , which is similar, so is this the inrush current of this motor?
I need the causes, and if possible I want to know what is the proper way to solve this problem? Is it good to use soft starter?
Update:
These Vacuum cleaner motor we used in our devices are Brushes.
