What is the difference between AC motor speed and DC motor speed?

What is the difference between AC motor speed and DC motor speed?

Answer:

Because the exchange is easier to obtain, easier to transport, so at present we use most of the electric machinery is AC motor driven, AC motor applications more widely.
DC motorThe stator of a direct current motor is a fixed magnetic field, and the direct current changes through the brush of the rotor to form a magnetic field around it, thereby rotating in the stator. In industrial enterprises, due to relatively reliable DC power supply, DC motor is generally used to require reliable operation of mechanical or mechanical spare security; and because the DC motor with variable speed input voltage can also change, so often need to control local DC motor are many, such as milling machine, planer, electric vehicles, subway trains and so on.
Alternating current dynamoAC motor is rotating to produce a rotating magnetic field formed by the stator voltage in the rotor should be on the.The speed is generally fixed speed. But because of its simple structure and convenient power supply, it is widely used in industrial enterprises. Small to household refrigerators, washing machines, vacuum cleaners, large machine tools, and so on, all use AC motors.
