Description

A kind of motor electricity saving speed regulator

The utility model relates to a kind of motor electricity saving speed regulating device, and the electric energy secondary that especially the motor work done can be consumed is used, and also is adapted to the motor electricity saving speed regulator that storage battery is made power supply.

Known at present, alternating current motor is made of rotor, stator, stator coil, main shaft, shell, end cap, and stator coil has star and dihedral connection.Direct current machine is made of rotor, rotor coil, stator, stator coil, (or permanent-magnet stator), main shaft, carbon brush, commutator, shell, end cap.These motor mostly are disposable consumed power works done, all not the used electric energy second use of motor work done, cause waste of energy.

The purpose of this utility model provides a kind of motor electricity saving speed regulator, and it can not only make the normal work done of motor, and can regulate motor speed and power.Can also use the secondary that obtains of the used electric energy 10%-30% of motor work done, or the feedback charging is used after the rectification.

The purpose of this utility model is to realize like this, constitute direct current machine by the two poles of the earth permanent-magnet stator, two pawl rotors, rotor coil, main shaft, commutator, slip ring, carbon brush, shell, end cap, it is characterized in that disconnecting by serial connection place in the middle of two rotor coils, the disconnection head of two coils, be connected on respectively on two slip rings on the main shaft, draw on the casing outer terminal by the carbon brush that is arranged on the slip ring.Drawing two outer the end of a thread of casing joins through deconcentrator and output boostering transformer primary coil again, the elementary tap of output transformer is connected on respectively on each contact of deconcentrator, this moment, output transformer just sealed in the middle of two rotor coils, formed rotor coil and output boostering transformer series loop.Regulate what of the output boostering transformer primary coil number of turns with deconcentrator, the total impedance in the circuit is along with the increase or the minimizing of the number of turns, and changes.Electric current in the circuit and voltage also change thereupon.Reach the adjusting of electric machine speed regulation and power output and voltage.Since direct current machine be by carbon brush to rotor coil commutation power supply rotation, thereby between two rotor coils with regard to exportable alternating current.When motor was unloaded, current sinking was little, and the electric current of the output transformer of flowing through is also little, and output voltage is also low.When increasing load to motor, anxious poly-increase of current sinking, the electric current of the output transformer of flowing through also increases, the voltage of output raises, when motor load one regularly, give that output transformer is secondary to add a load, the transformer total impedance diminishes, the flow through electric current of motor of power supply increases, electrical power increases, and gives the added load of output boostering transformer big more, and the electric current of the motor of flowing through is big more, electrical power improves, and rotating speed is fast more.Form proportional relationship.Provide though the energy of two kinds of series loads all is power supply, the step-up transformer that is output of the big current drain 10%-30% when moving because of the motor work done is exported, and obtains secondary and uses.The electric energy that is output just is output utilization after the motor work done.Can after rectification, feed back to charge in batteries again, prolong the service time of storage battery, reach the purpose of motor power saving speed regulator.Single-phase or the threephase stator coil of alternating current machine disconnects the tail end of coil every respectively, disconnect head and draw casing, be connected on leading-out end single-phase respectively or three-phase output boostering transformer primary coil on, see that the elementary coil tap of figure (2) is connected on respectively on each contact of deconcentrator, use through the output boostering transformer coupling direct secondary that boosts.

Owing to take such scheme: can make electric motor normal working, the electric energy 10%-30% that the motor work done can be consumed obtains the secondary application again.Also scalable motor power (output) and rotating speed only need to connect a deconcentrator and output boostering transformer to motor, and be simple in structure.
