What is the difference between dc motor and ac motor?
In theory, dc motor can be used as a generator in the theory of direct current and ac motor
The dc motor is the magnetic field, which is moving in the field. Ac motor is a magnetic field rotating motion, while the conductor does not move. Dc motor are divided into stator winding and rotor winding. The stator winding magnetic field is produced. When general dc. The stator winding is fixed polarity of the magnetic field generated. The rotor flux direct current in the magnetic field force. The rotor in the magnetic field force then spin. Direct current institutions to build complex. Cost is high. Ac motor stator winding and rotor conductors. Shaped like a squirrel cage rotor conductors between conductors and conductors with silicon steel sheet. Also have some ac motor rotor windings.
Series type of ac motor and dc motor structure, such as hair dryer, crusher, hand electric drill, etc. Used in the motor, just can't like dc motor with permanent magnets to generate the magnetic field. There is a commutator, carbon brush, there is electric spark in the work, the noise is bigger. General induction ac motor commutator and carbon brush, the input current of stator, rotor coil produces eddy current magnetic field, no spark, noise is small in work.
