Hairdryers are being advertised as having a AC motor or DC motor which on is best?
Household current is A/C, and direct battery is D/C. Not too many motors operate on both types of current, especially any appliance that has a speed control or rheostat. To really answer your question,, I would have to see the exact wording of the add. Is this a commercial or hand held home hair drier? Or one that can be used in a automobile or camper?
I have never seen a DC hairdryer or seen one advertised except for ones you can plug into a car or boat. These will be way less effective than an AC dryer as DC circuits can barely manage 200W.
A wound field DC motor will run on AC, through connecting the sector winding in sequence with the armature. an basic DC gadget related like this regardless of the indisputable fact that would have intense losses: DC gadget designed for this want a laminated stator magnetic circuit, different sensible there will be eddy modern losses interior the stator iron. DC motor with a laminated stator, with a chain field connection are additionally oftentimes used as a 'common motor' because of the fact that's going to run from AC or DC. they're utilized in many cases in family contributors home equipment (like vacuum cleaners and washing machines). of course, AC supply could be recified to DC to run an basic DC gadget. AC automobiles won't run from DC. some digital circuitry is mandatory (noted as an inverter) to produce AC from the DC supply to run an AC motor. automobiles additionally oftentimes used as 'brushless DC automobiles' are easily a sort of synchronous motor (AC), and want particular circuitry to run, from a DC supply.
It's irrelevant which motor is in it for performance. When you buy a blow dryer you should be looking for the wattage, fan output (CFM), and different speeds of the unit. If that doesn't separate one from the other, then start looking at features like cool shot, accessories. If it has an AC motor there are less electronic parts inside since no conversion is needed to power the DC motor with wall voltage.
All modern hair dryers use a DC motor, whether the input to the hair dryer is AC or DC. In AC-powered hair dryers, there are a set of diodes that convert to AC voltage to a pulsating DC voltage. I've repaired hair dryers that were made in the 60's and they had DC motors too. Is the DC hair dryer one that will work from a vehicle connection? If so, it will not produce nearly as much heat as an AC-powered unit that plugs into the wall. If these are your choices, then AC powered is definitely the way to go
