Wholesale Powerful Brushless Vacuum Cleaner OEM, Factory, Supplier, Manufacturer

Whether you are shopping for a sweeping robot or a vacuum cleaner, you will often see that on the color page of the product, the manufacturer specially marks you "we use a brushless motor", and then tells you that "brushless motor is powerful". So today, let's introduce what a brushless motor is and why a brushless motor can become the selling point of many manufacturers.

What is a motor?

Before we know about the brushless motor, let's first understand what is a motor.

A motor is an electromagnetic device that converts or transmits electric energy according to the law of electromagnetic induction.

In short, because electricity can not directly make a machine move directly, a machine needs to convert the energy of electricity into power to make the machine run. The motor is this machine.

The motor can be said to be the core of a household appliance. Without the motor, the washing machine can't rotate, and the vacuum cleaner can't absorb dust. Therefore, only when the motor is good can the product have core competitiveness.

Working principle of a brushless motor

It can be imagined that there is a cylinder with a magnet rotating in the middle, and the column wall is no longer the two magnetic poles of the magnet, but an electrified "fan blade". In this way, as long as the power is on, the column wall has a magnetic pole because of the electromagnetic field and generates a mutual repulsion force with the middle magnet. Then the magnet rotates wildly, and the electric energy is converted into kinetic energy.

Difference between brushless motor and brush motor

The carbon brush of the brush motor needs to constantly rub with the coil connector to supply power to the motor. Therefore, the faster the speed of the motor, the more severe the friction between the two, and the faster the temperature rises. Moreover, after the friction reaches a certain degree, it needs to be repaired.

The brushless motor can achieve high speed after removing the brush and reducing the friction of the brush. The noise is much lower. Because the wear of the motor is much less, the service life is relatively longer.

Advantages of a brushless motor for vacuum cleaner

A brushless DC motor, referred to as BLDC for short, is a new type of variable speed motor. It has good speed regulation characteristics of DC motor, but because there is no commutator, it can be made into a non-contact type. It has the advantages of simple structure, convenient manufacture, and no regular maintenance. It is an ideal variable speed motor.

• A brushless motor has the obvious characteristics of high efficiency, large power, small volume, and high control precision. It is widely used in the field of the vacuum cleaner.

• The brushless DC motor has good speed regulation performance. It adopts electronic commutation and pulse width modulation pulse speed regulation. While further improving the performance of the DC motor, it also overcomes a series of problems caused by the traditional mechanical commutation of the DC motor, thereby extending The service life of the motor.

• The control circuits of the brushless DC motor mainly include a control circuit microprocessor, data signal processor, and special integrated motor.

• The frequency measurement, phase commutation, control, and adjustment are realized by software.

• The fan in the vacuum cleaner and the motor driving the brush using a DC motor, which does not need speed regulation and commutation, and the control method is relatively simple.

• DC motor has good linear speed regulation characteristics, simple control performance, high efficiency, and good dynamic characteristics. It has always occupied the traditional position of speed regulation control.
