Vad är en frekvensomvandlare?

En frekvensomriktare styr motorns varvtal genom att ändra elnätets frekvens från vanlig 50 Hz till högre, uppåt 65 Hz, eller lägre, nedåt 5–10 Hz.. ABB har frekvensomriktare för motorer från 0,18 kW till 5,6 MW. Vanligaste användningsområdet är för pumpar och fläktar.

Can I run a 12V motor on 24V?

I have run 12V power window motors at 24V for minutes at a time. They get hot, but I haven’t had one fail from overheating yet. On the other hand, motors which are already pushed to nearly their limits to begin with shouldn’t be run above their rated voltage. Motors such as the ridiculously high-power brushless motors used in drones, for example.

How can I tell if my 12V motor is good enough?

Put your hand on the motor and see how hot it is getting and use your common sense and judgement. While there are 12VDC motors that drive extreme loads (the starter motor in an automobile for example), most 12VDC motors are for much lighter loads.

What is the resistance of a 12V DC toy motor?

Going on to the technicality of the problem, the 12 V DC toy-motor has a very low resistance typically drawing a current of about 0.5 A at full load. Although this depends upon the type and make of the motor (but I am assuming it to be a general 12V DC motors used in toys).

What is the difference between 48V motor and 12V motor?

One is 48V motor and other is 12V motor which delivers the same power. Now as well know that power is Voltage times Current. So Current ( I ) is Power/Voltage.
