I've looked up your model vacuum cleaner, and it seems that I am able to still get this motor for your Eureka central vacuum cleaner. We're located in the United States, but we can certainly ship this to you.
Here's a picture of the diagram for you;
We sell the genuine Eureka motor for $199.00, however you may save substantially on this motor by purchasing it under the Lamb Electric name. The motors are identical, and Lamb actually makes this motor for Electrolux, and sells the replacement parts for MUCH less money they Electrolux. We sell the motor under the Lamb name for $119. I went ahead and added this part to our site so you could place your order if you wanted to. I don't have it in stock today, but my parts distributor is showing 3 in stock, so we can easily have your order shipped out within 2-4 business days.
Here's the link to the Eureka CV1801 Central Vacuum Cleaner motor, Part number 54586;
