Ac induction motor is running ahead of the motor, ac voltage is widely used in electric fans, refrigerators, washing machines, air conditioner, hair dryer, vacuum cleaners, dishwashers and electric lampblack machine, sewing machine, food processing machine and household appliances and power tools, small electrical equipment. Ac induction motor is divided into induction motor and motor commutator. Induction motor and single-phase ac asynchronous motors, into the motor and motor and push spending. The rotor speed motor speed (less than) a rotating magnetic field, which call for the speed of the induction motor. It and induction motor is basically the same as. S = (ns - n) / ns. S for the slip for magnetic speed, ns for rotor speed, n. Basic principle: (1) when the three-phase asynchronous motor three-phase ac power, access three-phase symmetric three-phase stator winding through the three-phase current to produce the stator flux emfs (MMF) and rotate a rotating magnetic field. (2) the rotating magnetic rotor is relative motion, cutting conductors according to the principle of electromagnetic induction, rotor induced electromotive force and conductor of induced current. (3) according to law, electromagnetic flow field of the rotor conductor in electric magnetic effect, formed by electromagnetic torque, drive shaft rotation, when the motor rotor with mechanical load, the output energy to. Asynchronous motor is a kind of ac motor, the speed and load the grid frequency ratio is not constant relations. As the size of the load changes. Load torque is larger, the lower the rotor speed. Asynchronous motors including induction motor, doubly-fed induction motor and motor commutator. The most widely induction motor, will not lead to misunderstanding or confusion circumstances, the general induction motor can be said for the induction motor. Common asynchronous motor stator windings exchange network, and other rotor windings without power connection. Therefore, it is simple in structure, manufacture, use and maintenance convenience, quality and reliable operation of smaller, lower-cost advantages. Asynchronous motors have higher efficiency and better work, from no load to full load operation within the scope of nearly constant speed, and can satisfy the most agricultural production of mechanical transmission requirements. Asynchronous motor also facilitate into various protection forms derived from different environment conditions, in order to adapt to the need. Asynchronous motor, must draw from reactive power grid, the excitation electric power factor. Therefore, to drive the ball mill, the compressor, low speed of such power machinery and equipment, often USES synchronous motor. Due to the speed of the induction motor with rotating magnetic speed has turned bad relationships, the poor performance of speed motor commutator (except). A broad and smooth to request the speed range transport machinery, machine, printing and dyeing, large and papermaking machinery, adopts dc motor is economic, convenient. But with the power electronic devices and ac drive system development, now applies to the wide speed of asynchronous motor speed and efficiency of dc motor has with comparable.
