Brush drill and brushless drill which is good? What is the difference between the two?

Hammer drill, mainly used for drilling, is an indispensable power tool for decoration or maintenance, widely used, not only convenient for production, but also good use effect, but in the purchase of time, often hear the brush and brushless points, many friends do not understand, is not a drill, there is what brushless points?

In fact, it is not difficult to understand that when purchasing, we really need to know the difference between brush and brushless, brush refers to the carbon brush, the use of the commutation of the brush to ensure the normal operation of the motor; On the contrary, brushless no carbon brush, Hall sensor reversing, drive to ensure the normal operation of the motor, then in the end is the brush drill, or the brushless drill is good? What's the difference? This is also a problem that we are more concerned about, let's analyze it, let's have a look!

1. Advantages and disadvantages of brushed electric drill

1. Advantages: The brush drill is relatively cheaper, the structure is relatively simple, the control is relatively easy, the current is relatively large when starting, the start is fast, the torque is large, the weight effect is good, and the speed is relatively stable.

2. Disadvantages: the friction of the carbon brush, easy to produce electrical sparks, can not be used in many occasions, and there is a certain electromagnetic interference to the outside world, easy to heat, relatively low efficiency, short life, but also often replace the carbon brush, more trouble.

Two, the advantages and disadvantages of brushless electric drill

1. Advantages: Hall sensor and driver instead of carbon brush, no friction, low noise, a wider range of application, some precision areas are also applicable, basically do not need any maintenance, the application life is relatively long, especially for speed control is relatively high.

2. Disadvantages: a little expensive, relatively brush structure is more complex, the design is relatively difficult.

Brushless electric drill or brush electric drill? The above has made a simple comparison, relatively speaking, certainly brushless electric drill is better, and more comfortable to use.
