Abstract

The invention discloses a device for testing a controller of a BLDC (brushless DC) motor. The device comprises a bottom plate, a single-chip microcomputer and a first oscilloscope, wherein a left support plate and a right support plate are arranged on the bottom plate, and a load motor and a tested motor are arranged on right side surfaces of the left and right support plates respectively; a shaftof the tested motor is in drive connection with a shaft of the load motor; adjustable resistor structures are connected to three-phase connection lines of the load motor; Hall sensing devices are mounted on three-phase connection lines of the tested motor respectively; each Hall sensing device comprises two binding posts, a U-shaped copper piece, a magnetic ring and a Hall sensor; each Hall sensor is connected with the single-chip microcomputer connected with a computer, and a virtual oscilloscope is arranged in the computer; the three-phase connection lines of the tested motor and a ground line are connected with the first oscilloscope. The coaxiality between the shaft of the tested motor and the shaft of the load motor can be improved, the torque of the load motor can be adjusted, and the test accuracy is higher.

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...
