Problems solved by technology

After the motor flows into high-order harmonics, it will cause the motor to heat up and accelerate the aging of the motor windings, which is not good for the motor
Many people don’t know how to match the parameters of the input and output reactors when applying frequency converters. If they are too large, the cost will be too high, and if they are too small, they will not be effective. Therefore, the current technology and applications have defects and cannot meet the requirements of universal application and multi-field intelligent control.

Description

technical field [0001] The invention relates to a management system, in particular to a motor power-saving intelligent management and control system. Background technique [0002] In the industrial field, the drive and control of AC motors are inseparable from speed regulation, such as constant pressure and constant flow in water pumps, constant pressure and pressure maintenance of air compressors, speed control of elevator production lines, etc. are all inseparable from speed regulation control. At present, most of the market applications are simple controls for frequency converters. Frequency converter technology is a very mature product on the market at present, and its principle is the AC-DC-AC process, which brings a new revolution to the control field. If the application of frequency conversion is not understood or unreasonable, it will cause pollution to the power grid and shorten the service life of the motor. The higher harmonics will flow into the power grid to f...
