It is the beauty within the machine.
-
@pumpSHO It spins at 104,000 rpm
-
How can this be a switched reluctance motor if it has a Neodymium rotor? this makes no sense
-
I wonder if the Neodymium in the motor will lose its magnetism over time.
-
humm..i did not relize they had Neodymium Rare Earth magnets in them!

To clean the loop amplifier, you just wipe it with a soft, dry cloth. The air intake can be cleaned with any vacuum cleaner - use a soft dusting brush.
There is no need to clean the impeller.
-
How do you clean the air intakes and the impeller? Will I need a special Dyson vacuum cleaner? I think we should be told.
-
how is this different from the brushless DC motor?

Review: Dyson Zorb Dry-Cleaning Powderby vintagehoover15,790 views
I guess that his brushless motors are either 4:4 (ie 4 teeth both on stator and rotor) single phase switched reluctance motors (cheap motor and feed electronics but apt to be noisy) or 2 pole, single phase synchronous motors with a 'C-core' stator and a small-diameter rotor based on high-performance magnet material and possibly steel for strength. Neither basic configuration is new in my opinion but Dyson has done very well to develop good designs and impressive speeds in consumer products.

@oakapple5 The Digital Motor V2 was developed in Malmesbury, England, by Dyson's team of 45 motor engineers, over a period of about 10 years. It's manufactured in one of their their own facilities in Singapore, and protected by 15 patents. This is the sense in which Dyson mean it's 'new': it's not a pre-existing motor they purchase from a specialist manufacturer; before Dyson began making it, it didn't exist, and you can only find it in Dyson appliances.
