Abstract

The invention discloses a debugging system for a motor. The debugging system comprises a computer, a motor driving part and a serial port communication converting part, wherein the motor driving part comprises a DSP (Digital signal Processor) control module, a rectifier module, an IGBT (Insulated Gate Bipolar Transistor) inverter module, a switch power supply module, a driving module and an over-current, over-voltage and over-temperature protecting module. The debugging system disclosed by the invention can be used for acquiring actual voltage signals, current signals, rotating speed signals and the like and acquiring an internal control variable.

Description

technical field [0001] The invention relates to the field of motor control, in particular to a motor debugging system. Background technique [0002] The traditional motor debugging system mainly uses traditional test instruments to collect data such as voltage, current, power, speed, and torque. Through manual reading, data recording, and curve drawing, the measurement and control speed is slow, the data is inaccurate, and the data processing and analysis are complicated. , and it is especially difficult to measure multiple signals at the same time for graphical comparison. [0003] Many motor debugging platforms developed at present have the following problems: [0004] (1) It can only meet the needs of specific users, such as Starter and Drivemonitor, the on-site debugging tools for transmission equipment developed by Siemens, can only be used in specific occasions; [0005] (2) RS232, RS485, USB and other communication methods are mostly used, and motors are mostly used...
