Abstract

The invention discloses a device and a method for fan motor electromotive force measurement. A wind tunnel which can change the wind amount is used for generating fluid, the fluid is used for guiding a fan motor to be measured to rotate, the motor three-phase induction voltage is measured, the induced electromotive force constant is obtained, and whether the induced electromotive force constant meets requirements is detected. By the aid of the technology, the fan motor to be measured can acquire the stable rotary speed quickly, compressed air is not used, the measurement of the induced electromotive force constant under the rated speed and different rotary speeds is conducted, key characteristic parameters of the fan motor to be measured can be obtained and the motor eddy current effect can be observed qualitatively.
