A mini folding washing machine has recently become a hit online, attracting a lot of attention. Folding washing machines are characterized by their small size and foldable design. Whether it’s a large washing machine or a newer portable folding washing machine, a micro DC motor is a key component. So, what kind of motor does a folding washing machine use? Below, XD Micro Motor provides a detailed introduction.
The selection of a motor for a folding washing machine needs to meet two important characteristics. First, it must have high torque; if the torque is too low, it cannot drive the load, so it needs to be paired with a reduction gear to obtain greater torque. Second, noise is crucial; excessive noise from the folding washing machine motor is very unpleasant for the user experience, so noise optimization is necessary.
Most folding washing machine motors on the market currently use micro motors from the 3530 and 3429 series. These motors employ a strong magnetic structure paired with a reduction gearbox, resulting in high torque and a noise level of only 50 decibels—lower than normal conversation. This eliminates noise pollution during washing, and imported carbon fiber ensures a long service life. The 3530 folding washing machine motor measures only 35mm x 30mm, significantly saving space.
Important parameters to consider when selecting a motor for a folding washing machine:
1) Voltage: Determines the speed of the drive motor in a folding washing machine; the higher the voltage, the higher the speed.
2) Spindle speed: The rotation speed of the motor in a folding washing machine. The faster the spindle speed, the lower the torque, and vice versa.
3) Speed ratio: The larger the speed ratio, the lower the output speed of the reducer, and the greater the torque;
4) Torque: Determines the load weight that can be driven. Insufficient torque will prevent the folding washing machine from operating.
Folding washing machine drive motors can be divided into two types: brushed motors and brushless motors. So, should a folding washing machine use a brushed motor or a brushless motor?
In terms of overall motor performance, brushless motors have the advantages of long service life and no brushes, and their performance is superior to that of brushed DC motors. However, brushless motors are relatively expensive and have more complex speed control methods, generally costing 2 to 3 times more than brushed DC motors. This is obviously too expensive for folding washing machines, so most folding washing machines on the market use brushed DC motors.
Folding washing machine motors are characterized by high speed, convenient and stable speed adjustment, and low cost, but they have low output torque. Therefore, they need to be used in conjunction with a gear reducer to achieve high torque output while reducing the output speed.
Features of Folding Washing Machine Motors
1) Folding washing machine motors have a simple structure, mature technology, and low cost: The motor is composed of components such as stator, rotor, commutator, and brushes, and its price and cost are much lower than those of brushless motors;
2) Simple and convenient speed adjustment: The speed of the folding washing machine motor can be adjusted by adjusting the power supply voltage, unlike brushless motors which require changing the control signal and then using a microprocessor to change the power to adjust the speed.
3) Fast response and high starting torque: The folding washing machine with brushed DC motor has a fast starting response and very smooth speed change. The vibration is almost imperceptible from 0 to the maximum speed, and it can drive a larger load when starting.
4) Smooth operation and good starting and braking performance: Because brushed motors regulate speed through voltage adjustment, they start and brake smoothly, and also run smoothly at constant speed. In contrast, brushless motors are controlled by digital frequency conversion, so they are not smooth during starting and braking and have large vibrations. They only run smoothly when the speed is constant.
5) High control precision of brushed DC motor: The motor of a folding washing machine is usually used with a gearbox, which makes the motor output power greater and the control precision higher.
