Description
Technical field
The present invention relates to synchronous motor equipment technical field, more particularly to a kind of ultrahigh-efficiency three-phase asynchronous motor.
Background technology
Motor is a kind of equipment for converting electrical current into mechanical energy.It is to use the power on coil (namely stator winding)
Produce rotating excitation field and act on rotor (such as squirrel-cage closure aluminium frame) and form electro-magnetic motor force rotation torque.Motor is pressed using electricity
Source difference is divided into dc motor and ac motor, and the motor in power system is largely alternating current generator, can be same
Step motor either asynchronous machine (motor stator rotational speed of magnetic field does not keep synchronous speed with rotor rotary rpm).Motor it is main by
Stator is constituted with rotor, and the direction of electrified wire movement under force in magnetic field is with the sense of current and magnetic induction line (magnetic direction) direction
It is relevant.Electric motor operation principle is effect of the magnetic field to electric current stress, makes motor rotation.Although China's motor product species is numerous

Field technique is carried forward vigorously, optimized development a collection of high-efficient energy-saving environment friendly major products, eliminates the motor product of a collection of common efficiency,
Promote model change.When the threephase stator winding (respectively 120 degree of electrical angles of difference) of motor, three-phase symmetrical alternating current is passed through
Afterwards, a rotating excitation field will be produced, the rotating excitation field cutting rotor winding (turns so as to produce induced-current in rotor windings
Sub- winding is close access), the rotor conductor of current-carrying will produce electromagnetic force under the effect of stator rotating excitation field, so as to turn in motor
Electromagnetic torque, drive motor rotation are formed on axle, and motor direction of rotation is identical with rotating excitation field direction.Current China makes
Threephase asynchronous speed governing is more difficult, on rotor core and is not added with winding, causes threephase asynchronous work
Make less efficient.
