In electric vehicles, the motor is a very important key parts, this article the brushless dc motor with you to understand in the south of anhui three-phase asynchronous ac motor car how to generate power! How to generate power ac asynchronous motor? The working principle of ac motor, electric winding turn in a rotating magnetic field. In the motor stator and rotor is not contact, why to stator winding on alternating current (ac), the rotor will rotate? Its working principle is applied to the electromagnetic principle: two Faraday's law and lenz's law. When on the stator coil winding on alternating current (ac), due to the characteristics of alternating current, the stator windings creates a rotating electromagnetic field. On the rotor winding is a closed loop conductor, it is in the stator's rotating magnetic field is constantly cutting stator magnetic induction line. According to Faraday's law, part of the closed conductor in magnetic field cutting of magnetic induction line movement, creates an electric current from a conductor, and the electric current and an electromagnetic field. So, in the motor have two electromagnetic field: one is connected to external after alternating current and the stator electromagnetic field; The other one is caused by cutting of stator induction current after the formation of the rotor electromagnetic field. According to lenz's law, the magnetic field induced current total want to rebel against the causes of induced current (Cutting rotor winding of the stator magnetic induction line), that is, do our best to make the rotor conductor is no longer on the cutting of the stator magnetic field of magnetic induction line, the result is that: on the rotor conductor will & other; Chase & throughout; The stator's rotating electromagnetic field, that is, make the rotor with the stator rotating electromagnetic field rotation, eventually make the motor begins to rotate. Since the rotor is always in & other; Chase & throughout; The rotation speed of the stator electromagnetic fields, and in order to be able to cut lines of magnetic induction and induced current, rotor speed is always a bit slower than the speed of the stator electromagnetic field (About 2% ~ 5%), that is, the asynchronous operation, so we called this induced current motor ac asynchronous motor. The following is the structure of the unidirectional ac motor: gm ac asynchronous motor structure is as follows: in this paper, from the mechanical industry publishing house why electric cars running.
