    Electric motor is a machine that converts electrical energy into mechanical energy, which is divided into AC motor and DC motor, Each have advantages and disadvantages between them. 
    1.Use the power is not the same, The AC motor is AC power source, such as 220v / 380v alternating current, alternator; DC motor use DC power supply, such as batteries.
    2.AC motors compared to DC motors, more reliable, cost cheaper than DC motors, mainly used in industrial production.
    3.Structure is different, a DC motor commutator more than AC motors, DC power supply relatively easy to carry out, which is the most important difference between them.
    4.DC motor is AC motor speed range is opposite bigger, smooth and easy to control, easy to control, fast high performance, speed is the energy consumption is small, frequent starting to adapt to the occasion, widely used DC motors can be used to screw jacks starts. However, the DC motor commutation difficulties, poor reliability.
    5.DC motors easier than AC motor speed control, but need more than AC motor maintenance.
