Abstract
The invention provides an intelligent temperature control motor controller. A three-phase AC power supply is rectified into DC power and then is provided for a controller, afterwards, a program already programmed by a computer is input to a simulator, when an external temperature sensor acquires a temperature change signal, the signal is directly uploaded to the simulator, at the moment, the simulator carries out option comparison according to the program programmed by the computer and the temperature signal input by the temperature sensor, afterwards, intervention is performed on DC voltage of the controller and current output, the DC power output by the controller is converted into sine pulse voltage through a converter, the voltage can enable a motor to rotate and can also change the program as a temperature changes at the same time, when the program changes, the DC output of the controller also changes along to enable the rotating speed of the motor to be changed, and thus poleless speed adjustment on a three-phase AC motor is formed. At the same time, since the motor is often at a low-voltage small-current working state, energy is conserved and power is saved. When the output voltage of the controller is higher, the output current is larger, the rotating speed of the motor is faster. Since the controller is at a low-voltage small-current state during operation, the controller also has a poleless speed adjusting function while saving the energy.
Description
Art
One, to rely on ambient temperature signal, carries out selecting journey automatically, and the direct current controlling controller exports size, and what reach control three phase alternating current motor rotating speed is intelligent temperature control electric machine controller.
Background technology
Current, control the mode of three phase alternating current motor revolution normally: Mining converter technique.Namely change a-c cycle with frequency converter and change motor speed.Mining makes motor external control volume strengthen in this way, and the use cost of motor adds a lot, and is not easy to safeguard.
Summary of the invention
In order to solve the pattern relying on large volume frequency converter variable frequency adjustment three phase alternating current motor rotating speed.We have invented one and three-phase alternating-current supply is become direct current through over commutation, be then supplied to controller.Afterwards, the program that computer is finished is input in simulator.When external temperature sensor Mining collection can directly upload in simulator to during variations in temperature signal.At this moment the program that simulator can be finished according to computer and the temperature signal that temperature sensor input comes are compared option.Afterwards to the direct voltage of controller, the output of electric current is intervened.The direct current that controller exports becomes sine pulse voltage after transducer.This voltage not only can make electric machine rotation, simultaneously also can because of temperature change routine change.When routine change Time Controller direct current export also thereupon change motor speed is changed.Define the stepless time adjustment to three phase alternating current motor.Motor is often in low-voltage, small area analysis operating state simultaneously.Mining produces the intelligent temperature control electric machine controller manufactured in this way.It is low that it has cost, and volume is little, and quality is light.Owing to being in low-voltage when it works, small area analysis state, therefore energy saving.When controller output voltage is higher, when output current is larger, the rotating speed of motor is faster.Therefore the while of energy-conservation, it also has stepless time adjustment function.
Accompanying drawing explanation
Below in conjunction with accompanying drawing embodiment, the present invention is further described.

embodiment
During enforcement, first switch on power, intelligent temperature control electric machine controller just enters complete machine holding state, all existing electricity of three phase mains 1 rectifier 2 controller 3 process simulator 4 at this moment.
Then computer line 7 is connected with computer interface 8 and carries out on computers programming and input among process simulator 4.
When opening temperature sensor 6 temperature signal just can be uploaded to process simulator 4. now process simulator 4 start, the temperature signal that input is come in is compared option, the program command after comparison is sent to controller.This instruction be namely by computer line 7 computer interface 8 input come computer input program.Just can according to program control direct voltage after contrast program command received by controller, the output of size of current, direct voltage, the output size of electric current, the speed that decide motor speed plays the function of speed governing.
The DC voltage and current that via controller 3 exports becomes half-sinusoid pulse voltage supply motor through transducer 5 again makes its work.The voltage that this motor rotation speed and controller 3 export and current related.
