Abstract

The invention provides a rotating speed testing device and a rotating speed testing method for a DC motor, and a testing system for an air conditioner, wherein the rotating speed testing device of the DC motor comprises the components of a first port set which is connected with a to-be-tested DC motor and comprises a motor operation signal feedback end; a second port set which is connected with the control circuit board of the DC motor, wherein each port in the second port set is correspondingly connected with a corresponding port in the second port set; a processing module which is used for calculating the actual rotating speed of the DC motor according to a signal that is fed back by the operating signal feedback end of the motor; a setting module which is used for setting the target rotating speed of the DC motor; and a display module which is used for displaying the actual rotating speed and / or the target rotating speed of the DC motor. The rotating speed testing device and the rotating speed testing method for the DC motor and the testing system for the air conditioner have advantages of improving testing efficiency for the DC motor, furthermore reducing manpower cost in testing of the DC motor, and realizing multi-aspect testing on the DC motor.

Description

technical field [0001] The invention relates to the technical field of motor testing, in particular to a rotational speed testing device for a DC motor, a testing system for an air conditioner and a testing method for a rotational speed of a DC motor. Background technique [0002] At present, for the speed test of the DC fan with side air outlet structure, the oscilloscope is generally used to monitor the pulse signal of the motor operation, and then the fan speed is manually calculated (calculated according to outputting N pulse signals per revolution), which is not only inefficient, but also Moreover, the control logic when the fan speed deviates cannot be simulated. [0003] Therefore, how to improve the testing efficiency of the DC fan and at the same time reduce the labor cost of the DC fan test has become an urgent technical problem to be solved. Contents of the invention [0004] The present invention aims to solve at least one of the technical problems existing in...
