Voltage-stabilizing tested rotation speed automatic adjustment-type motor testing system

Abstract

The invention discloses a voltage-stabilizing tested rotation speed automatic adjustment-type motor testing system, which is characterized by being composed of a single chip microcomputer, a rotation speed signal acquisition unit, a variable frequency motor control unit, an output display unit and an operation unit connected with the single chip microcomputer respectively, a tested motor connected with the rotation speed signal acquisition unit, a variable frequency motor connected with the tested motor, and a voltage-stabilizing power supply module connected with the variable frequency motor, and the variable frequency motor is also connected with the variable frequency motor control unit. The rotation speed of the tested motor can be quickly adjusted during the test process so as to test parameters of the tested motor at a different rotation speed, and the motor test efficiency is improved. Stable work voltage is provided for the variable frequency motor and the tested motor, the variable frequency motor and the tested motor can work stably, and a tester can evaluate the performance of the tested motor conveniently.

Description

technical field [0001] The invention relates to a motor test system, in particular to a voltage-stabilized 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 performance of the motor under...
