Which price is higher, AC motor or direct current motor? Which one has a longer service life?
1, under the premise of the same capacity, because the DC motor sales volume is small, copper is used more, so the price is more expensive than the AC motor;2 because of brush DC motor needs to be replaced frequently, if included in the life, the working life of DC motor AC motor is short, if not included in the replacement of the working life of two kinds of brush, the service life of the motor is basically the same
It can only be said that the cost of DC is higher (in comparable conditions)AC motor life, a little bit of the conference room
The DC motor, relying on power, motor rotation, heat production, but the effect is better. Therefore, when in use, according to the needs of choice.
Exactly, if it is of the same size, should be AC motor, low price, long service life, AC motor makes the rotor rotating by electromagnetic induction, relative power, and internal heat production is less than that of dc;
