Description
Technical field
The present invention relates to machine field, relate generally to the temperature control system of blower motor.
Background technology
Motor is the important component part of blower fan, because running for a long time, motor temperature is higher, if taking corresponding measure not in time, it is possible to can cause that motor is burned out, and serious even can burn whole blower fan. Monitoring to motor internal temperature is an important step. Know motor internal temperature in time, just can take cooling measure or out of service. Existing temperature detection is all the temperature of the electrode afterbody of detection, has certain temperature difference with the temperature of motor internal stator and rotor; And big by external environment influence, the temperature of detection is inaccurate.
Summary of the invention
In order to overcome disadvantages mentioned above, the present invention provides a kind of blower motor temperature control system, including motor, the first temperature sensor, the second temperature sensor, the first signal generator, secondary signal generator and PLC control system; Described motor includes stator and rotor; Described first temperature sensor is arranged on described stator; Described second temperature sensor is arranged on described rotor; Described first temperature sensor is connected with described first signal generator; Described second temperature sensor is connected with described secondary signal generator; Described PLC control system includes controlling switch, display, temperature signal receptor and processor; The wireless signal that described first temperature sensor of reception of described temperature signal receptor and described second sensor send; Described processor connects described temperature signal receptor, controls switch and display; Described switch connects motor.
Further, described stator and be respectively arranged with through hole on described rotor, described first temperature sensor and described second temperature sensor are separately mounted to inside two described through holes.
Further, described PLC control system also includes alarm device, and described alarm device is connected with the described switch that controls.
Further, described PLC control system is arranged on the outside of described motor
Blower motor temperature control system provided by the invention, temperature sensor is arranged on stator and rotor, is positioned at motor internal, affected by environment little, and detection temperature is accurate; Provide the temperature of motor internal, the situation that motor runs can be grasped better; With PLC control system, it is possible to adjust, according to motor internal temperature, the state that motor runs in time, extend the service life of motor;It is provided with display, it is possible to monitor temperature intuitively, contributes to staff and be managed.
Accompanying drawing explanation
Fig. 1 is the structural representation of the stator of temperature control system provided by the invention and rotor.
Fig. 2 is the figure of the PLC control system of temperature control system provided by the invention.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in further details.
As shown in Figure 1 and Figure 2, blower motor temperature control system provided by the invention, including motor, first temperature sensor the 130, second temperature sensor the 140, first signal generator 150, secondary signal generator 160 and PLC control system 200. Described motor includes stator 110 and rotor 120. Described stator 110 and described rotor 120 there are through hole, described first temperature sensor 130 and described first signal generator 140 are arranged in the through hole on described stator 110; Described second temperature sensor 140 and described secondary signal generator 150 are arranged in the through hole on described rotor 120. Described first temperature sensor 130 and described first signal generator 150 connect, and described second temperature sensor 140 and described secondary signal generator 160 connect. Described PLC control system 220 includes controlling switch 210, display 220, temperature signal receptor 230, processor 240 and alarm device 250. Described processor 240 is connected with described control switch 210, described display 220 and described temperature signal receptor 230; The described switch 210 that controls is connected with described motor and described alarm device 250.
When blower fan is started working, described motor also begins to run, then described first temperature sensor 130 and described second temperature sensor 140 start to detect the temperature of described stator 110 and described rotor 120; Then the temperature of measurement is sent on described first signal generator 150 and described secondary signal generator 160. Described first signal generator 150 and described secondary signal generator 160 are by temperature signal transfer-out. Temperature signal receptor 230 in described PLC control system 200 receives temperature signal, and is sent to by temperature signal in described processor 240. Described processor 240 will be sent on described display 220 after processes temperature signal, described display 220 shows the temperature on described stator 110 and described rotor 120 in the way of numeral. Described PLC control system 200 arranges two temperature: stop temperature and operating temperature. When the temperature on described stator 110 and described rotor 120 is higher than when stopping temperature, then described processor 220 controls the described switch that controls and 210 cuts out by described motor. When, after described control switch 210 generation actions, described alarm device 250 is activated warning, reminds staff's temperature too high. When the temperature on described stator 110 and described rotor 120 is lower than operating temperature, then described processor 220 controls the described switch that controls and 210 is opened by described motor.
These are only preferred embodiment of the present invention, therefore can not limit scope of the invention process according to this, the equivalence namely made according to description of the present invention changes and decoration, all should belong in the scope that the present invention covers.
