Abstract

The invention provides an on-line detecting method of frequency-changing speed-adjusting numerically-controlled machine tool main shaft motor output power. By obtaining the needed basic data for detecting frequency-changing speed-adjusting numerically-controlled machine tool main shaft motor output power and the expression of main shaft motor no-load power and frequency, only the real-time input power, the input voltage and power supply frequency of a frequency-changing speed-adjusting numerically-controlled machine tool main shaft motor are detected on line, and the output power of the main shaft motor can be detected on line in real time. An on-line detecting process is simple and easy to operate, and the method is commonly suitable for existing frequency-changing speed-adjusting numerically-controlled machine tools.

Description

technical field

[0001] The invention belongs to the technical field of energy saving of machine tools, and relates to an online detection method for the output power of a spindle motor of a frequency conversion and speed regulation numerically controlled machine tool. Background technique

[0002] As the research and application of machining energy efficiency is rapidly rising around the world, it is necessary to analyze the energy consumption of each component or link of the machine tool. When conducting machine tool energy consumption tests, machine tool motor efficiency tests, and researching machine tool energy-saving technologies, it is necessary to detect the output power of the machine tool spindle motor. Since the spindle motor of the machine tool has been fixedly connected with the machine tool, it is very difficult to directly detect the output power of the spindle motor.

[0003] CNC machine tool is the abbreviation of Computer numerical control machine tools. CN...
