Then, use infrared or synchronous flash, or use the waveform processor to obtain the operating frequency, and order the induced electromotive force constant of the fan motor (4). =/3⁄4^Experience formula (see formula (2) below): (2) where, skill: motor eddy current loss A: eddy current constant of core material /: motor running frequency nine: magnetic flux density in iron core: iron core material The thickness can understand the magnitude of the motor eddy current and the square of the rotational speed. There is a linear proportional relationship. In other words, as the motor speed increases, Ϊ = current loss will increase rapidly, because the horse violates the vortex step w Ο ® how to observe the motor qualitatively The vortex should be of the same importance. In order to qualitatively understand the eddy current loss induced by the 定子达定子石石钢片, f is used to induce the electromotive force to the different speeds of the line = to observe the developed motor and the calibrated motor (this motor performance is the standard) The difference in the degree of eddy current loss between the two is based on the improvement of motor efficiency. /, 感应 is the induced electromotive force constant in the magnetic circuit parameters of the permanent magnet motor, which is closely related to the motorized 201133012 iH output and the operable vehicular rpm. Several methods are known: 1 and the method for measuring the induced electromotive force constant are as follows The method is disclosed in US Pat. No. 69-4 - the measurement of the motor induced electromotive force constant in the phase rotation mode, the motor two = = intersection (four) axis (four) service speed relationship, the St technology has some problems and Disadvantages, the patent fan is a three-phase permanent magnet type sensing motor. By means of Huo: the rotor position, the speed is output by a speed encoder, and the three-phase permanent magnet cannot be implemented in a single phase. The fan motor-the method is the Republic of China Patent No. 65, which discloses the inductive signal detection device for the motor of the coil, and uses a Hall element to sound the angular position of the motor to drive: the output of the λ coil is used for signal transmission. Check out. (4) = There are some _ and shortcomings in the method and technology. The patent is ==fan, and the system is a sensing motor. Although the _^ page is added to the signal coil when the Hall element is not transmitted, this method Not suitable for mass production potential constant Γ, Γ方料* wide range (4) 朗 motor induction electric: if the connection: the; r-relay... for the _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ 74, and the compressed air is directly blown through the air gun 72 to the blade 731 of the fan motor 73 to be tested, the driving blade 731 is rotated, and then a speed measuring device 74 (infrared or synchronous strobe) is used to detect The running speed is measured. The value of the running speed is transmitted to a computer 75 or a waveform processor through a computer port 751 to obtain the operating frequency, and the purpose of measuring the electrical characteristics of the fan motor is achieved. However, the above method has some problems and shortcomings. The air is directly blown to the blade 731 through the air grab 72, and the rotation speed thereof is not easy to control, and only one region of the blade Φ 7 31 will be subjected to gas pressure, which will cause the induced electromotive force measurement. The value error also easily causes the rotation of the connecting blade 731 to be skewed and damaged, and also affects the measurement value of Kemax. Moreover, this method also fails to operate the fan motor 73 to be tested at different stable rotational speeds. Since the induced electromotive force constant affects the torque output size and performance of the motor itself, how to propose that the fan motor to be tested can be operated to the desired speed in the undriven state, and can be maintained at this operating speed while Different stable running speeds can be achieved to obtain the induced electromotive force constants at different speeds mentioned above. In this way, the post-processing work can be performed without additional software to solve the measurement problem caused by the instability of the motor speed, and the degree of eddy current effect can be further obtained. Above, the previous technology can not provide an effective solution. Accordingly, the present invention provides an apparatus and method for measuring the induced electromotive force constant of a motor, which can solve the aforementioned drawbacks of the prior art. SUMMARY OF THE INVENTION 201133012 Based on solving the above-mentioned shortcomings of the prior art, the present invention is a device and method architecture for measuring the electric potential of a fan motor, the main purpose of which is to provide a principle of using a small wind tunnel device; using a flow field in a non-contact manner The driving fan blade rotates, and is characterized in that it can provide a controllable different shifting blade rotation to a single or a plurality of different stable rotational speeds: no need to = ΐ source and controller drive motor rotation, and can quickly and accurately determine the motor f speed When the fan motor to be tested is driven to a predetermined speed: the 曰 does not wave n test # The motor's induction power repeatedly, the operating frequency., Method ': Its invention is a kind of fan motor electromotive force measurement: The fan motor and the auxiliary fan ride to - the detection motor of the fan motor to be tested has been activated; if the book is operated, if it is the next step; if it is the execution of the computer, the detection software of the computer is to be tested.

The fan motor induces the electromotive force to the 19~ the computer to be tested _; " ^ The actual value of the aforementioned pre-heart-beating motor induced electromotive force to determine whether the fan motor to be tested is good: Action; if it is otherwise Execute 20! After the action is triggered, the action is recorded; and the computer 20 judges whether the operation of the fan motor to be tested is finished, if == all the above steps are performed; if yes, the process is directly performed. The measuring method of the induced electromotive force constant of the micro motor 201133012 method and device 'mainly uses a small wind tunnel device, the device is provided with a cavity; one end of the cavity is provided with a fluid generating device and a fixing seat for generating a fluid device, the fluid The flow generated by the generating device can be controlled, and the other end of the cavity is provided with a fan motor mount to be tested, and the fan motor to be tested is mounted on the fixed seat. The device is provided with an automatic adjustment system for the fan motor speed to be tested. The system is provided with an oscilloscope and a computer. The oscilloscope measures the phase voltage and the running frequency of the fan motor, and the waveform of the phase induced voltage is recorded by the oscilloscope through the computer software. Program calculation and comparison to set the difference between the actual speed and the actual speed, and adjust the fluid generating device. When the speed of the fan motor to be tested reaches the set speed; start measuring the phase induced voltage and the running frequency of the fan motor. Inductive electric and frequency, according to the phase-sensing electric bunker and the operating frequency, the motor induced electromotive force constant is obtained through the conventional sensing phase and the rotational speed of the motor, and the design value is compared with the design value to identify whether it is qualified.
