there is no such motor, digital is binary and a motor cant run on binary a false claim

Digital? It has a little man blipping the armature with his finger to keep it spinning....

It is a elec motor were it speed and out torque is controlled by a digital circuit or device.

its totally false advertising they should say our digital control circuit a digital motor doesn't exist
What is really meant is electronically commutated dc motor... Where the changing magnetic field is contolled by semiconductors rather than a mechanical brush/ commutator. Two main types - open loop ... Where the field is switched in an arbitrary manner. And closed loop where the shaft position is monitored and the field switched in response. Removing the need for brushes simplifies the mechanical system and allows the motor to run faster.

When have adverts ever told the truth?

you still need to get power to the coils on the armature so how can you do away with the carbon brushes, you could have a fixed magnet armature or an electrical armature which requires power

just read its a fixed magnet with field coils so all that's controlled are the field coils via digital circuitry but still not a digital motor which ever way you look at it
Either have a permanent magnet armature (simplest), an induction motor armature (with induced field).. or the compromise arrangement of slipring feeding the armature (like a car alternator). In fact there are some marketed systems for converting car alternators into electronically commutated motors.

I had a job building prototypes of these back in the late 80's. Most of them were 3 phase permanent magnet (neodymium or samarium cobalt magnets) motors and had hall-effect sensors to provide feedback to the drive. Some had encoders or resolvers on them. Nowadays they are very common but back then loads of money.
No. Not garbage. That's pretty much it.
You can argue stepper motors are digital. I can see why they'd be used in a scanner but not in a vacuum cleaner.
Digital control as mentioned before, but that's not a digital motor, it's a digitally controlled motor.
Dunno, but I suspect it's a totally bogus advertising campaign.
A stepper motor?

Something you ought to be sure is much better than the not totally clear alternative, which is presumably an analogue motor, although they were never called that. If you are not so assured, judge yourself an inferior person. You know, we live in a digital age and all like that.
The thing with advertising is that it aims to disarm critical thought, in fact slyly suggest that anything of the sort is clearly ridiculous.
