Abstract

The invention relates to the technical field of motor detection and specifically provides a DC motor detection system including a programmable logic controller, a motor driving circuit, a Hall currentsensor, a Hall voltage sensor, a torque sensor and a rotation speed sensor. The programmable logic controller also includes a data detection module, a data processing and test flow selection module and a state machine control module. When a motor is working, the Hall current sensor, the Hall voltage sensor, the torque sensor and the speed sensor send current, voltage, torque and a rotation speedof the real-time operation of the motor to the data detection module. The data detection module carries out analog / digital conversion on the received data and transmits the data to the data processingand test flow selection module. The data processing and test flow selection module processes the received data to obtain test data and a fitted curve. The DC motor detection system of the present invention has the advantages of high reliability, high precision and long-term monitoring.

Description

technical field [0001] The invention relates to the technical field of motor detection, in particular to a DC motor detection system and method. Background technique [0002] The motor is an important electromagnetic device, which is used in many fields and places. The motor often works in extremely harsh environments. The harsh application environment makes the motor more vulnerable to damage, especially the highest frequency of overload, short circuit, and lack of phase faults. Therefore, for Motor testing is very important. [0003] At present, with regard to the DC motor detection system, the existing technology is generally a single index measurement or simple data can be measured, through the data acquisition card, test platform, sensor, etc., when the motor is detected, the motor is placed on the test platform, Among them, the speed sensor, torque sensor and current sensor are used to detect the speed, torque and current of the motor, and output the detected data to ...
