Technical field
The utility model relates to measurement of rotating speed technical field, more specifically, relates to a kind of device for testing rotating speed of air conditioner fan motor.
Background technology
In prior art, the measurement of rotating speed of the fan electromotor of air conditioner industry is mostly used and dodges rotational speed meters frequently.In test process, dodging rotational speed meters frequently needs hand-held, and need on the blade of fan electromotor, paste sheet metal, then by reflection of light, calculate rotating speed, measuring process needs constantly to regulate the speed of stroboscopic, until vision is seen the static of sheet metal, could judge rotating speed, this just brings following problem: 1, measurement of rotating speed overlong time, inefficiency; 2, because needing the static of eyes judgement sheet metal, just must be near the fan blade of High Rotation Speed, this brings very high potential safety hazard in some specific occasions; 3, can not immediately dynamically monitor rotating speed; 4, measurement of rotating speed result out of true.
Utility model content
The utility model is intended to solve the problems of the technologies described above at least to a certain extent.
The purpose of this utility model is to provide a kind of can intuitively demonstration, at-once monitor, the device for testing rotating speed of air conditioner fan motor safe and convenient to use.
The utility model solves the technical scheme that its technical matters adopts: a kind of device for testing rotating speed of air conditioner fan motor, comprise tachometer gage, switch and connector, described switch is located between tachometer gage and connector, and described tachometer gage is connected with fan electromotor by connector.
The utility model is connected by connector tachometer gage with fan electromotor to be measured, actual speed that can instant playback fan electromotor to be measured improves testing efficiency, intuitive display, and be non-contact testing, safe and convenient to use.
In one embodiment, between described tachometer gage and switch, be provided with divider resistance, can to fan electromotor to be measured, carry out dividing potential drop by divider resistance, thereby can adapt to the variation of different motor models, there is wider using adaptability.Preferably, described divider resistance is two, is respectively the resistance with different resistance values.
In one embodiment, the model of described tachometer gage is DM4A-FR1.
In one embodiment, described switch is double-point double-throw switch.
In one embodiment, described connector is light current connector.
The beneficial effects of the utility model are: the utility model can be used for measuring PG and the DC motor speed of air conditioner industry main flow, intuitive display, and dynamic monitoring, instant playback, non-contact measurement, resolution characteristic is strong, and power consumption is little, safe and convenient to use.
