Variable-frequency speed-regulating motors and ordinary motors are widely used in household equipment and are important power output equipment.Inverter Motor Factory-Wanbang Motor reminds that there is no fundamental difference in appearance between a variable frequency motor and an ordinary motor, but the difference is that the variable frequency speed regulation motor can be connected to the frequency converter for variable frequency speed regulation, while the ordinary motor can only be used with constant power and constant speed.
The important reason for the difference between the use of variable frequency motors and ordinary motors is the difference in layout, mainly in the following aspects.
1. Insulation grade: The insulation grade of the variable frequency speed control motor is generally F grade or higher, which enhances the insulation strength to the ground and the insulation strength of the turns, and especially considers the ability of the insulation to withstand the attack voltage.The general insulation grade of ordinary motors is F.
2. Dealing with the vibration and noise of the motor: The variable frequency motor manufacturer fully considers the rigidity of the variable frequency speed control motor components and the overall rigidity, and strives to increase its natural frequency to avoid resonance with various force waves.
Therefore, the vibration and noise of the frequency conversion motor are lower than ordinary electric secrets.
3. The difference between the cooling method of the frequency conversion motor and the ordinary motor: the frequency conversion speed control motor recycles forced ventilation cooling, that is, the frequency conversion motor heat dissipation fan recycles an independent fan drive, while the common motor heat dissipation fan blade is on the motor shaft, and the heat dissipation efficiency is related to the motor speed.
4. The inverter motor optimizes the method of preventing shaft current. The inverter motor manufacturer will recover the bearing insulation method for the inverter motor with a capacity of 160KW higher.
The main reason is that high-power variable frequency motors are prone to magnetic circuit difference and shaft current. When the currents generated by other high-frequency components are united and contaminated, the shaft current will greatly increase, resulting in bearing damage, so insulation is generally adopted. Way.
