With the growth of family properties, variable frequency motors have become the preferred power output equipment for medium and high-end machinery and equipment manufacturers, because variable frequency motors have the characteristics of high efficiency, energy saving, speed regulation, etc., especially the high-power variable frequency motors used in large-scale machinery and equipment, and the energy-saving results are more obvious. .Therefore, variable frequency motor manufacturers guarantee the reliability of high-power variable frequency motors is the most important thing in the production of enterprises.

　　Looking at all electrical energy consumption in household applications, about 70% of motors are used for fans and pump loads. The advantages of energy saving and emission reduction of this type of load are obvious: huge economic benefits and continuous growth social effects .Precisely based on the above goals, the application of frequency conversion speed regulation of exchange motors is extremely widespread.For example, a variable-frequency exhaust fan, when the required exhaust air volume of the fan is low, it is only necessary to control the low speed of the variable-frequency motor and eliminate the output driving power.

　　In addition to energy saving, high efficiency and ease of use, variable frequency motors also have the advantage of soft start. There is no need to check the starting function. The only key problem that variable frequency motor manufacturers need to deal with is: it is necessary to enhance and improve the ability of variable frequency motors to adapt to non-sine wave power sources and increase the power of frequency conversion. Reliability of the motor utilization.

　　The current variable frequency motor manufacturers mainly guarantee the reliability of the use of high-power variable frequency motors from the design structure and material utilization.

　　Class B temperature rise design of high-power variable frequency motor, F-class insulation manufacturing.The recycling of polymer insulation materials and the vacuum pressure dipping paint manufacturing process and the recycling of extraordinary insulation layout have greatly improved the insulation withstand voltage of electrical windings and the strength of the machine, which are capable of high-speed motor operation and withstand high-frequency current attacks and voltages of inverters. Crush the insulation.

　　The frequency conversion motor has high balanced quality, and the vibration grade is R-class machine parts with high processing accuracy, and special high-precision bearings are recycled, which can run at high speed.

　　The frequency conversion motor recycles the forced ventilation and heat dissipation system, and all recycles the inlet axial flow fan with ultra-quiet, long life and strong wind.Ensure that the motor obtains effective heat dissipation at any speed, and can achieve high-speed or low-speed permanent operation.

　　Comparing with traditional variable frequency motors, it has a wider range of speed regulation and higher design quality. The extraordinary magnetic field design further suppresses the high-order harmonic magnetic field to satisfy the design indicators of broadband, energy saving and low noise.It has a wide range of constant torque and power speed regulation characteristics, stable speed regulation, and no torque ripple.

　　It has excellent parameter matching with all kinds of frequency converters and common vector control, which can realize zero-speed full torque, low-frequency large-scale torque and high-precision speed control, position control and fast dynamic response control.
