Differences, advantages and disadvantages of variable frequency, fixed frequency and direct drive motors for washing machines
Household appliances using frequency conversion technology are very common in life, such as inverter air conditioners have great advantages in energy saving, and the temperature fluctuation of inverter refrigerators is very small. So, what is the difference between frequency conversion and fixed frequency of washing machine products? What are their advantages and disadvantages? Share it for everyone today.
The inner barrel of the washing machine is driven by an electric motor, while the fixed frequency motor is a fixed frequency washing machine, and the frequency conversion motor is a frequency conversion washing machine.
1, the principle of fixed frequency washing machine
Once the fixed-frequency washing machine starts working, the speed of the motor will remain the same and keep going until the washing is completed.
Advantages and Disadvantages of Fixed-Frequency Washing Machine: Due to the simple program setting, the washing process is not complicated and the price is low. The disadvantage is that continuous high-speed operation not only consumes electricity, but also damages the clothes very much, and the clothes are often knotted.
2, the principle of inverter washing machine
The inverter washing machine presses the switch, the motor starts at a low speed, spreads the place where the clothes are screwed, then fills the water, the motor accelerates, shakes the clothes in the water, further accelerates and changes direction, washes the clothes, then decelerates and shakes, then discharges the water Rinse, then slowly wash and dry at high speed.
Advantages and Disadvantages of Inverter Washing Machine: Because the frequency conversion technology can control the motor speed, it not only saves energy and saves electricity, but also reduces damage to clothes and reduces the entanglement and wear of clothes. Since the rotation speed can be appropriately adjusted with the weight of the clothes, the sound and vibration can be effectively slowed down. However, compared with ordinary fixed-frequency washing machines, the price of inverter washing machines will be much higher.
3, direct drive washing machine
Direct drive motor washing machine refers to the direct connection between the washing machine drum and the drive motor, eliminating the traditional intermediate parts such as the wheel, belt and clutch.
The direct drive motor washing machine makes the motor coincide with the center of rotation of the inner cylinder, ensuring that the offset of the inner cylinder is small, reducing the equipment failure rate and the noise of the belt transmission.
