Abstract
The utility model relates to an electricity-saving controller, particularly an electricity-saving controller for motors. The utility model is mainly composed of a rectifying circuit, a control circuit and a thyristor. The utility model utilizes the switching characteristic that the current flowing through the motor is changed to flow to a bidirectional diode when the load is provided, the control pole of a thyristor is controlled, and the thyristor is switched on or switched off. The voltage drop of the motor falls down on the silicon control when the load is not provided, and the goal of energy saving is achieved. The utility model has the advantages of simple structure, good energy-saving effect, low cost, etc., and especially suitable for the motor of the sewing machine.
Description
The utility model relates to a kind of electricity-saving controller, refers in particular to a kind of electricity-saving control device of motor.
Known from institute, motor in the course of the work, running into through regular meeting has load and non-loaded state.Under non-loaded situation, the situation of low load with strong power appears through regular meeting, i.e. and motor idle running like this, just makes electric energy slatterned in vain.
The purpose of this utility model is to overcome above-mentioned weak point of the prior art, and a kind of electricity-saving controller is provided.
The utility model is achieved by the following scheme: utilize the variation of the electric current of the motor of flowing through when load is arranged, switching characteristic by bidirectional diode, the control silicon controlled control utmost point, make controllable silicon conducting be arranged when carrying or end during in the motor no-load at motor, thereby make the drop of pressure of motor when non-loaded on controllable silicon, reach purpose of energy saving.
The utlity model has simple in structure, good energy-conserving effect, advantage such as price is low is particularly suitable for using on the motor of sewing machine etc.
Below in conjunction with accompanying drawing the utility model is further specified:
Accompanying drawing 1 is the utility model block diagram.
Accompanying drawing 2 is the utility model electrical schematic diagram.
See accompanying drawing 1, the utility model is by rectification circuit 1, control circuit 2, and controllable silicon 3 is formed.The input of the output connection control circuit 2 of rectification circuit 1, the anode of an output termination controllable silicon 3 of control circuit 2, the control utmost point of another output termination controllable silicon 3, the negative electrode of controllable silicon 3 and load 4 are serially connected in the loop.
See accompanying drawing 1,2, rectification circuit 1 comprises transformer B, diode D1-D4, capacitor C 2, resistance R 3; Control circuit 2 comprises current relay L
z, resistance R 1, R2, capacitor C 1, bidirectional diode ST, when load when being unloaded, the electric current after rectification circuit 1 rectification makes the current relay L in the control circuit 2
zSwitch be in normally open.When the positive half cycle of input ac voltage V0 by the resistance R 1 in the control circuit 2, R2, capacitor C 1 is given trigger impulse voltage of bidirectional diode ST, controllable silicon SCR is in cuts the state of going up, its terminal voltage V
zBe V approximately
oHalf, at this moment, the terminal voltage V in the load
fBe V approximately
oHalf.
When load was carried for having, electric current increased in the circuit, the primary voltage V of the transformer B in the rectification circuit 1
1Also increase, secondary coil obtains a bigger coupled voltages V
2Process bridge full-wave rectifier and filtering are added to the current relay L of control circuit 2
z, because current relay L
zThe increase of electric current on the coil, cause the K switch adhesive, become closure state by normally open, its E point voltage raises, the voltage that capacitor C 1 is filled when adding positive half cycle, cause bidirectional trigger diode ST conducting, make the full conducting of controllable silicon SCR, change conducting state into from cut-off state, at this moment, the terminal voltage of controllable silicon SCR is zero volt, and the terminal voltage of load 4 can promptly be got back to V
o
In like manner, when load was zero load again, electric current reduced, and K switch becomes normally open by closure, controllable silicon 3 not conductings, its terminal voltage V
zBe again V
oHalf, at this moment, the terminal voltage V in the load
fAlso be V approximately
oHalf.
