Different appliances have different design goals for the motors. For example I have a blender, that is probably used a few hours over it's entire lifetime. So, you can design in a very powerful, efficient motor, with diagnostic, variable drive, controller etc. Or find the cheapest rotating thing, and attach a blade for it. The first one would be acceptable for a blender for an ice cream factory I guess, but I'm using mine maybe once a week.
Actually the EU commission recently have been spending a lot of time optimizing the efficiency of white goods. They had new lays for vacuum cleaners and the controversial kettle law. So there is a push to reduce wasted energy.
These guys probably found out that many 20-30 year old building appliances, HVAC could be more efficient with these motors. (I've studied about them in university BTW) Good for you, start replacing old motors, make money. It's actually very nice, that they correctly identified the market niche for their product.
