Abstract

The invention provides a brushless motor multifunctional test circuit, which comprises a rectifier and filter module circuit, an AC module display connection module circuit, a signal feedback connection module circuit and an ON / OFF switch timing module circuit. When the brushless motor multifunctional test circuit provided by the invention tests an AC / EC brushless motor, the test result can be displayed visually through the AC power supply LED display screens of the rectifier and filter module circuit and the AC module display connection module circuit, the signal feedback connection module circuit can be connected to test a fan with high and low level signal output of the AC / EC brushless motor or the like, the ON / OFF switch timing module circuit can be connected to simulate an ON / OFF switch of a user side and conduct other experiments, so that the brushless fan can bear switching of more than 1K times, and the fan performance and surge switch sparking resistance can be well detected.

Description

technical field [0001] The invention relates to the detection field of a brushless motor multifunctional test board, in particular to a brushless motor multifunctional test circuit. Background technique [0002] The use of brushless motors will definitely switch ON / OFF multiple times. It is impossible to test the ability of the motor to resist continuous switching once or twice during the switch. AC / EC-related brushless motors with various level outputs have a single detection method and mostly use an oscilloscope for detection, which cannot be well and intuitively understood by people who do not understand. Contents of the invention [0003] Aiming at the above-mentioned deficiencies in the prior art, the present invention provides a multifunctional test circuit for a brushless motor, which is simple in circuit, convenient in operation, intuitive in test results, and convenient for popularization. [0004] In order to achieve the above-mentioned purpose of the invention,...
