Description
Technical field
The utility model relates to the device field that utilizes solar energy to produce mechanical work, is specially a kind of solar water pump that adopts permagnetic synchronous motor.
Background technique
Along with pay attention to day by day, the development and use of solar energy are applied in the various activities in production just more and more widely new energy.A kind of solar water pump is arranged now, utilize solar cell that solar energy converting is become the electric energy drive motor, again by the driven by motor pump working.The output voltage of solar cell is relevant with intensity of sunshine; Output voltage can be higher when sunshine is strong; And motor adopts brushless direct-current (brushless direct current is called for short BLDC) motor more at present, when supplying with the overtension of motor; Flowing through the electric current of motor also can be too high, thereby makes the overheated of motor and damage.
The model utility content
In order to overcome the defective of existing technology, provide a kind of and control accurately, be swift in response, the safe and reliable solar device that utilizes, the utility model discloses a kind of solar water pump that adopts permagnetic synchronous motor.
The utility model reaches goal of the invention through following technological scheme:
A kind of solar water pump that adopts permagnetic synchronous motor; Comprise motor, water pump and solar cell; Motor is connected with the used for solar batteries lead, and the output shaft of motor is connected with water pump through retarder, it is characterized in that: also comprise current sensor, controller, input device and output unit; Current sensor is connected on the lead that connects motor and solar cell; Motor, current sensor, input device and output unit all pass through order wire and are connected controller, and motor is selected the permanent-magnet synchronous electrode for use, and controller is selected single-chip microcomputer or microcomputer for use.
The solar water pump of described employing permagnetic synchronous motor is characterized in that: input device is selected keyboard or touch screen for use, and output unit is selected display device or touch screen for use.
When the utility model uses, at first passing through input device input current critical value I in controller
0, when motor moved, current sensor transmitted current current value I to controller in real time, as I>=I
0The time, controller judges that this moment, motor was in over-current state, and then controller control motor reduces rotating speed to reduce output torque, and I is also corresponding to reduce I＜I
0The time remove control to motor.
The utility model has been controlled the electric current when motor moves effectively, has avoided crossing overheated and other hazards of stream, guarantees the safety of water pump, has also improved the performance of solar facilities.The beneficial effect of the utility model is: simple in structure, be swift in response, and control is accurately, and is safe and reliable, applied widely.
