What kind of applications use a dc motor?

Question

please give me a list of about 5 things in our daily lives that use a DC Motor.

Answer 1

Printers

Computer fans

Hard drives

Automotive electric motors for seat adjustment, window operation. wiper and heater/AC fan



Portable drills, and screw drivers



Cassette players (old school I know)

Answer 2

sure, yet on condition that the voltage is persevering with. maximum ammeters provides you you an rms AC reading of modern-day. ability at a particular on the spot in time is often V*I. If the voltage is persevering with, multiply the voltage by ability of the rms fee of modern-day to discover the widely used ability. If the voltage isn't consistent, multiplying the Vrms fee by ability of the Irms fee won't supply you the exceptional result. you like sum the instantaneous V*I values and divide the time over which the values have been summed (combine and divide by ability of the mixture time). one thank you to try this is to function a modern-day sense resistor (severe ability very low fee sub Ohm ability resistor) in sequence with the motor and use a 2-channel oscilloscope with math function. Channel A may be the voltage on the resistor (representing modern-day) and Channel B may be the voltage over the finished circuit (bear in mind channel A and B grounds might desire to be referenced to the comparable element). maximum present day scopes have Math purposes and you will show Channel A * Channel B (which would be with regards to ability and desires just to be scaled by ability of the resitor fee). seem on the rms measured fee of the maths waveform.

Answer 3

Any item that you put a battery in, uses DC. Any electronics/computer, use DC. Your car battery/eletical system, is DC.
