Embodiment Construction

[0010] Such as figure 1 As shown, it is a schematic diagram of the application of the testing device 20 of a preferred embodiment. The test device 20 is connected between the power source 10 and the motor 30. The testing device 20 converts the DC voltage provided by the power supply 10 into a DC voltage suitable for the operation of the motor 30, and intermittently provides the converted DC voltage to the motor 30 to complete the reliability test. Motor reliability test refers to the test whether the motor can continue to start normally after completing a specified number of power supply operations to the motor within a certain period of time.

[0011] Such as figure 2 As shown, it is figure 1 The specific functional module diagram of the test device 20. The test device 20 includes a voltage adjustment module 200, a conversion module 201, a reset module 203, a processing module 205, a switch module 207, and a display module 209. The conversion module 201 is connected to the vo...

Abstract

The invention relates to a testing device used for carrying out reliable testing on a motor. The testing device comprises a processing module and a switching module, wherein the processing module alternately outputs first control signals and second control signals to the switching module with a preset time interval; the switching module is turned off when the switching module receives the first control signals so as to supply direct current voltage provided by a power supply for the motor; and when the switching module receives the second control signals, the switching module is disconnected so as to stop supplying the direct current voltage for the motor.

Description

Technical field [0001] The invention relates to a testing device, in particular to a testing device for testing the reliability of drive components. Background technique [0002] Most consumer electronic products will use a drive component such as a motor. For example, in a DVD player, a motor drives the DVD disc to rotate to read the information stored in the DVD disc; in a wheeled smart toy, the motor drives the wheel to rotate to realize the front, back, left, and right movement of the wheeled smart toy. However, due to industrialized manufacturing, there are defective products in the manufactured motor products, so that the reliability of the motors assembled in consumer electronic products cannot be guaranteed, thereby affecting the quality of consumer electronic products. Summary of the invention [0003] In view of this, it is necessary to provide a testing device for testing the reliability of motor drive components. [0004] A testing device used for reliability testing o...
