Advantages of 48v Brushless DC Motor

Advantages of 48v brushless dc motor

There are three coils on the stator of the 48v brushless dc motor, each coil has two wires, and there are six leads in the motor. In fact, due to the internal wiring, it usually only needs three wires, but it is still one more than the previous DC motor (brush motor). Only by connecting the positive and negative electrodes of the battery will not move. The first characteristic of the BLDC motor is "high efficiency". The whirling force (torque) can be controlled to keep the maximum value at all times. If DC motor (brush motor) is used, the maximum torque can only be maintained for a moment, and the maximum value cannot always be maintained. If DC motor (brush motor) wants to get the same torque as the BLDC motor, only increase its magnet. That's why a small 48v brushless dc motor can also generate great power. The second characteristic is "good control", which is related to the first. 48v brushless dc motor can get exactly the torque and rotation you want. BLDC motor can accurately feedback the target rotation number, torque, and so on. Through precise control, the heating and power consumption of the motor can be restrained. If it is battery-driven, the drive time can be prolonged through careful control. In addition, it has the characteristics of durability and low electrical noise. These two points are the advantages of no brush. However, DC motor (brush motor) will have lost due to the contact between brush and commutator for a long time. Sparks can also be produced on the contact parts. Especially when the gap of the commutator touches the brush, there will be a huge spark and noise. If noise is not expected during use, a 48v brushless dc motor will be considered.

Advantages of 48v Brushless DC Motor

Where is 48v brushless dc motor with high efficiency, diversified control and long service life generally used? It is often used in the products which can play its high efficiency and long life. For example home appliances. Washing machines and air conditioners were used very early. Recently, a 48v brushless dc motor has been used in electric fans, and the power consumption has been reduced greatly. It is because of the high efficiency that the consumption of electricity is reduced. BLDC motor is also used in the vacuum cleaner. In one case, the number of rotations increased greatly by changing the control system. This example shows the good controllability of the BLDC motor. As an important storage medium, the rotating part of the hard disk also uses a BLDC motor. Since it is a motor that needs to run for a long time, durability is very important. Of course, it can also be used to curb power consumption. The high efficiency here is also related to the low consumption of electricity.
