Parts: Motor + Fan

Finding alternatives to motors is difficult because the motors used in vacuum cleaners are specialised for their job, they rotate at high RPM and are designed to cool themselves through the airflow they produce. Buying a motor to spec from a supplier might work for this first prototype but it is not sustainable as more people build their own open source vacuum cleaner.

So, the problem is also that anyone selling this type of product is going to be selling it in large volume for manufactures of vacuum cleaners. This doesn’t leave much option open for actually buying a motor and other types of motor are likely to be inappropriate for the task and suffer similar issues of quantity, but is there another way?

In recent years the growth of online spare parts suppliers means that it is now relatively easy to obtain a service part for almost any modern vacuum cleaner. The trick is that the motor it takes needs to be a popular one, i.e. one that is likely to be around for a long time, such that the project isn’t held at the mercy of the manufacturers obsoleting the product by discontinuing spares, even better would be a product that has third party substitute parts, however this is unlikely given the safety concerns of mains power and high speed mechanical parts.

An obvious choice would be to look at the popular products of the main manufacturers:

  • Electrolux
  • Vax
  • Dyson
  • Hoover
  • Numatic (Henry)

I am in discussion with a website called eSpares to find out what the most common parts are and therefore what are most likely to last the longest.
