Description
Technical field
The utility model relates to the start-up control device of direct current machine, especially the start-up control device of small-sized DC brushless electric machine.
Background technology
Power supply makes machine operation to motor to utilize solar energy, because energy savings, its application is more and more increasingly extensive.For example solar energy fountain sight, solar energy irrigation system or the like.The starting current that needs based on the DC water pump of brush motor is little, generally uses the power just can operate as normal as the 1.3-2 solar panel doubly of pump power.But the fatal weakness that the swabbing pump is arranged is that the life-span is short, and general stream time is no more than 2000 hours, compares high product so can not be used for life requirements.Dc brushless motor has long service life, and the advantage that efficient is high more and more has been used in fountain sight and other is used; But because the starting current that brushless electric machine needs is big, so be difficult to adopt solar cell for supplying power.And the power output that solar panel rated power produces when to be sunlight intensity reach 1000W/ square metre, under direct-connected mode, solar cell wants to allow brushless electric machine starting and operate as normal, its power not only will reach the power that the motor operate as normal requires, and will reach the instantaneous power that requires when starting.If at the period starter motor that compares the low light level, the solar cell that will use will be far longer than the power of motor so, generally will be at 2.5-3 times, so, not only increase the cost of solar cell, and may burn out motor the maximum at noon sun time.
Summary of the invention
The purpose of this utility model is: provide a kind of solar energy that utilizes to start the dc brushless motor control device.
The positive and negative electrode of solar cell connects the positive and negative electrode of storage battery, exports to the decision logic circuit; The decision logic circuit to be to connect, keep, to disconnect three kinds of mode control switch circuit, again by the switching circuit control brushless electric machine work that opens, stops work.
When the VP in the decision logic circuit＞V01, connect brushless electric machine and make it work.
When the V01＞PV in the decision logic circuit＞V02, keep the brushless electric machine standing state.
When the VP in the decision logic circuit＜V02, disconnect and stop brushless electric machine work.
Its advantage of the utility model is:
(1) saves solar panels greatly, reduced the integrated cost of whole solar water pump product, especially when water pump requires power big more, can embody the advantage that reduces cost more; (2) guaranteed that brushless water pump can operate as normal under certain sunlight; (3) prevent that water pump from starting repeatedly, prolonged the life-span of brushless water pump.
Description of drawings
Accompanying drawing 1 is a controlling party block diagram of the present utility model;
Accompanying drawing 2 is operating state waveform analysis figure of the present utility model;
Accompanying drawing 3 is control logic figure of the present utility model.
Embodiment
Brush DC starting mode of pump condition:
The pulse that produces a moment helps electrode to start, and this pulse will reach electrode and start needed voltage and time enough is arranged by motor rotation;
Judge that solar panel is having the voltage that produces under the load condition can be higher than the needed low-voltage of motor operate as normal, should be able to stop inadequately later, cause repeatedly to start and cisco unity malfunction to prevent electric start;
Maximally utilise solar energy, make the solar panel energy in a single day reach the needed minimum energy of motor operate as normal, just allow machine operation;
After solar light quits work than the light current machine, can rework automatically during the sunlight grow.
The utility model connects in the following way: the positive and negative electrode of solar cell connects the positive and negative electrode of storage battery, exports to the decision logic circuit; The decision logic circuit to be to connect, keep, to disconnect three kinds of mode control switch circuit, again by the switching circuit control brushless electric machine work that opens, stops work.When the VP in the decision logic circuit＞V01, connect brushless electric machine and make it work.When the V01＞PV in the decision logic circuit＞V02, keep the brushless electric machine standing state.When the VP in the decision logic circuit＜V02, disconnect and stop brushless electric machine work.
Generally start the brushless water pump of a 0.8W, need to adopt the solar panels of a 1.5W, and could start down at the later fine sunlight of Shenzhen 10:30 in the morning (about 75000LM light intensity).And utilize this technology, and adopt the solar panels of a 1W, under the fine sunlight (about 30000LM light intensity) of last Shenzhen noon 8:30, just can start fountain smoothly.Like this, make entire product not only reduce cost, and, the time range of spraying water improved greatly.
Implementation method
With electric capacity and solar cell parallel connection, allow solar cell accumulation of energy before exporting to motor; Capacitance is selected according to the size of electric motor starting electric current.
Utilize CMOS of a MCU or logical circuit control or NPN triode, as switch; This logic is V01 wherein: electric motor starting voltage; V02: motor operate as normal minimum voltage;
If adopt the MCU scheme, time that can a switch opens of program setting, like this this IC can adapt to certain limit power motor control and not needs change IC.
For different motors, by the method change V01 of change circuit " dummy load ", V02 realizes accurately control.
Process conditions
Be fit to the outside work condition ,-20 ℃-80 ℃; Waterproof, anticorrosion; Adopt water joint.
The small-sized solar fountain power of motor that adopts the brush DC water pump is at 0.5W-20W; Can be used for adopting the small-sized solar motor device of brush DC water pump, as: small-sizedly draw water, recycle unit etc. in the exhausting, suction, solar water heater.
