Abstract

The invention discloses a DC brushless motor controller testing device, which comprises a base plate, a single-chip microcomputer and a first oscilloscope, the base plate is provided with a left support plate and a right support plate, and the right sides of the left and right support plates are respectively provided with a load motor and a tested Motor; the shaft of the motor under test is connected to the shaft of the load motor; the three-phase connection line of the load motor is connected with an adjustable resistance structure; the three-phase connection line of the motor under test is respectively installed with a Hall sensor device; the Hall sensor The device includes two terminals, U-shaped copper parts, a magnetic ring and Hall sensors; each Hall sensor is connected to a single-chip microcomputer, the single-chip microcomputer is connected to a computer, and the computer has a built-in virtual oscilloscope; the three-phase wiring of the motor under test and the The ground wires are respectively connected to the first oscilloscope. The invention can improve the coaxiality between the shaft of the motor under test and the shaft of the load motor, can adjust the torque of the load motor, and has high test accuracy.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a testing device for a motor controller. Background technique [0002] Brushless DC motor (hereinafter referred to as BLDC). BLDC is widely used in daily life appliances, automobile industry, aviation, consumer electronics, medical electronics, industrial automation and other devices and instruments. As the name implies, BLDC does not use mechanical commutation brushes but directly uses electronic commutators, so BLDC has many advantages over brushed motors. [0003] The brushless DC motor consists of a motor body and a driver, and is a typical mechatronic product. A brushless motor refers to a motor without brushes and commutators (or collector rings), also known as a commutator-free motor. When the motor was born as early as the nineteenth century, the practical motor produced was a brushless form, that is, an AC squirrel-cage asynchronous motor, which was widely used. Howev...
