AC / DC motor
AC / DC motor
(OP)
Hi!
I am new here and I need some help. I am a student in Greece and I have a voluntary project for a water vortex and we want to use a motor. We prefer an AC motor with approximately 18000 rpm and 220V. We want this motor by Europe. Do you know where can I find one? I searched in Greek stores but there is nothing. Also, we prefer something cheap. If you have a better idea about the motor let me know.
Thanks a lot!

I believe aircraft use 400 Hz and some workshop tools like grinders run on a high frequency supply.
If you prefer using a universal motor consider a Vacuum cleaner, they run at very high speed.
Electric drill perhaps.

How about a DC motor?

Then if you want good industrial grade, Swiss made, check out EundA.ch - 600w probably about $ 1000.00

Here's a video showing a blender being disassembled. They spend a lot of time looking at the buttons, but in reality, all they do is signal the little printed circuit board to limit the voltage getting to the motor, essentially the equivalent of a dimmer device for lighting. If you look past that to where they show the motor, there are two wires going to it. Those will be AC input to the universal motor and you can wire a dimmer to them to vary the voltage getting to the motor instead of that PCB. Just make sure the dimmer is rated for the wattage of the motor.

Pick up an old one from a second hand store.
You may be able to get even higher speed by weakening the field independent of armature current.
