I am having a party for kids and have bouncing castles etc...5 motors in total...

I gave them electricity from a multiplug lead i have at home.

They are complaining that they have the motors working at low speed.

What can i do??

 

What is the rating of the motors?
What is the rating of your multiplug lead?
What is the rating of your mains circuit?

You may be overloading your multiplug and/or mains circuit which is potentially dangerous - it sounds lke the former.

Where are you? Here in the UK you can buy multiplug extension leads with 6 13A sockets on the end, but that certainly doesn't mean that it is possible or safe to draw 13A through each one.

 

Concur. It is common to try a 14 gauge extension cord that is far too skinny to carry the power for 5 motors. You probably need a fatter wire, or 2 of them. Look up the current on each motor, distance to the motors, and your local power voltage, and report back here for proper wire size.

 

How about some pics...
never hard of bouncing castles...
Sounds interesting..

I also have to concur with the earlier observation..
..
Have you verified that you have a "real" Heavy Duty extension cord (not a Chinees Heavy Duty - a real 10 gauge or 12 gauge one).
..
Also verify that the outlet(s) being used can supply the required current (power).

I reckon the party's been and gone by now.

Let's hope it wasn't too much of a let-down.

 

All of you where right. Thanks for your precious help.

I had to change the cable for a thicker one and it worked very fine!

Sorry only know time to reply you
