Voltage-stabilization-type test rotating speed automation adjusting type motor test system based on band-pass filtering

Abstract

The invention discloses a voltage-stabilization-type test rotating speed automation adjusting type motor test system based on band-pass filtering. The system is characterized in that the system is formed by a single chip microcomputer, a variable frequency motor control unit connected to the single chip microcomputer, an output display unit, an operation unit, a band-pass filtering unit, a rotating speed signal acquisition unit connected to the band-pass filtering unit, a tested motor connected to the rotating speed signal acquisition unit, a variable frequency motor connected to the tested motor and a voltage-stabilized power supply module connected to the variable frequency motor; and the variable frequency motor is also connected to a variable frequency motor control unit. In the invention, the band-pass filtering unit is arranged and can be used to filter an interference signal doped into a rotating speed signal so that an influence of the interference signal on the rotating speed signal is avoided and a test result of the tested motor is not influenced.

Description

technical field [0001] The invention relates to a motor test system, in particular to a band-pass filter-based voltage-stabilizing test speed automatic adjustment motor test system. Background technique [0002] With the development of the national economy and science and technology, motors play an increasingly important role in all walks of life. At the same time, with the development of various industries, higher and higher requirements are put forward for motor products. Therefore, before leaving the factory, motor products need to pass some test items to verify whether their characteristics meet the application requirements. Motor testing technology is of great significance to the performance verification of motors. However, the traditional motor test system is easily affected by the fluctuation of the system operating voltage when testing the motor, which makes the motor under test unable to run smoothly and normally, which affects the tester's evaluation of the perfor...
