Abstract

The invention provides a motor controller test box comprising a voltage detection module, a current detection module, a revolver decoding module, a signal display module and a single-chip microcomputer. The modules and the single-chip microcomputer are integrated. The revolver decoding module is connected with the single-chip microcomputer and used for receiving a revolver signal transmitted by a revolver and analyzing the revolver signal to obtain motor speed and rotor position. The signal display module is connected with the single-chip microcomputer and used for displaying voltage, current of each phase, speed and rotor position. The components such as the single-chip microcomputer are integrated and placed in one box; during test, a signal under test can be tested and displayed in the same time just by connecting a unit under test to the motor controller test box; the motor controller test box is simple to operate, small in size, convenient to carry and high in flexibility. The detection units in the motor controller box are already calibrated and can form a motor controller calibration system for a motor under test. If the data detected by the motor controller test box is inconsistent to that acquired by the motor controller, inaccurateness of a sensor in the motor controller is proved and calibration is required.

Description

technical field [0001] The invention relates to the technical field of motor testing, in particular to a motor controller test box. Background technique [0002] In the early stage of the independent development of the motor controller, multiple debugging is required to verify the underlying software. During the debugging process, it is necessary to calibrate and calibrate the input signal of the motor controller to ensure the accuracy of the input signal of the motor controller and ensure the good operation of the motor. If a traditional testing device is used, multiple testing instruments are required and the operation is complicated. The traditional motor rotor position and speed detection devices are mostly dynamometers, which have poor flexibility. [0003] Therefore, there are following deficiencies: the existing motor running detection device has complex structure, large volume, difficult portability and poor flexibility. Contents of the invention [0004] An obj...
