100W AC motor or DC motor good?
The advantages of DC motors (compared with AC motors) are: to achieve economic, smooth speed characteristics. And AC motor need to use inverter, electromagnetic regulator and other components to achieve this function.With the same power, the same speed (must be the same speed) compared with DC motor and AC motor, DC motor of the expensive price point, mainly because of its complicated structure must have "commutator" to achieve AC-DC conversion. This also increases the manufacturing cost of DC motors to a certain extent.
Depending on what you do with the motor, each has its own characteristics,The main difference between AC and DC motors is that the nature of the power supply is different. The AC motor uses alternating current. The generator sends out alternating current, while the direct current motor uses the direct current, and the generator sends out the DC point too
The alternator is concerned, it can realize the direct energy feedback to the grid (but must ensure 4 conditions: the same voltage amplitude, phase and phase sequence of the same, the same frequency); but the DC generator power is required to process the alternating current into the inverter (DC said rectifier, the DC the process that converts the AC inverter), to feedback to the grid. So it also needs to increase the power of the inverter.
