When we buy a washing machine, careful friends will find that there are generally two types of motors used in washing machines: one is a direct drive motor, and the other is a BLDC motor.
You should know that the motor is a very core component of the washing machine, which will directly affect the service life, running speed, noise, etc. of the washing machine. Therefore, when we buy a washing machine, from the perspective of motor performance, it is very important to choose which motor to use. So, there are direct drive motors and BLDC motors, which one is better to buy? Let me introduce these two motors to you, and then make a simple comparison. After reading it, you will know how to choose.
Direct drive motor is a kind of operation mode that cancels the belt as a transmission medium and turns to direct motor drive.
In the field of direct drive motors, Haier is currently doing very well. Many of Haier's high-end washing machines are basically equipped with this direct drive variable frequency motor.
For example, Haier's more representative high-end direct drive motor: Fisher & Paykel direct drive variable frequency motor.
BLDC motor is a way of connecting the drum through belts, pulleys, and pulleys. At present, most of the low-end and mid-end washing machines on the market use this BLDC variable frequency motor. Comparison
Compared to BLDC motors, direct-drive motors have the advantages of lower noise, higher stability and stronger power. Direct-drive motors are mainly used in high-end washing machines. Among them, the better motors are DD direct-drive variable frequency motors and BLDC variable frequency motors, which are relatively quieter, less vibrating and longer-lasting. The variable frequency mentioned here is used to reduce the noise during the operation of the washing machine. It will adjust itself according to the state, and it is mainly for drum machines, and the effect on pulsator machines is not obvious. Purchase suggestions From the perspective of motor performance, or the pursuit of silent effect, it is recommended that you first choose direct-drive variable frequency motors, and then consider BLDC variable frequency motors.
However, when we buy washing machines, we not only look at the washing machine motor, but also have to pay attention to the washing function and sterilization and mite removal function of the washing machine.
At present, the motors of drum washing machines on the market are mostly variable frequency motors, and most of them are BLDC variable frequency motors, especially mid- and low-end models. If your budget is not very large, there are basically not many choices for the motor of the washing machine
