Question:

Which price is higher for ac motor and dc motor? Which service lasts longer?

Which price is higher for ac motor and dc motor? Which service lasts longer?

Answer:

You can only say that the cost of dc is higher, (in comparability) The life of ac motor is a little bit
In the premise of the same capacity, because of the low sales of the dc motor and the quantity of copper, the price is more expensive than the ac motor. 2 because of the dc motor brush need to replace frequently, if included in its life, the working life of the dc motor is ac motor is short, if not included in the replacement of the working life of the brush, the life of the two kinds of motor is basically the same
Accurately, if is the same specification, should be ac motor price is low, service life is longer, through electromagnetic induction ac motor rotors, relatively save electricity, and the internal heat production is less than a dc; Dc motor, the electric motor turns the electric motor, produces heat fast, but the effect is better. Therefore, you should choose according to the requirements when using.
