Advantages and disadvantages of brushless motors

Advantages：

1. The machine runs quietly

This will be the direction that our civilized society will inevitably go. What other tools it requires to reduce noise to protect our sound environment. Now the most critical thing is to use it in some quiet places such as hospitals, banks, airports, schools and so on that need to be quiet.

2. No spark

In some occasions, you can show your skills There are some flammable and explosive places.

3. Long life

Because it replaces the commutator and carbon brush with a controller, it is several times or even a dozen times that of the brush motor. The life of the carbon brush is limited, for example, a thousand hours the carbon brush will wear out, and only the brush can be replaced but the motor can be replaced.

4. High speed

Because of the use of magnetic field induction there is no substantial contact speed can be done faster.

disadvantages:

1. High cost

The cost of the controller increases by at least a hundred yuan to take the micro motor. The cost of the original commutator and carbon brush is much lower.

2. Environment

if the environment used is in a place with a high magnetic field or has been in contact with or close to the high magnetic field, the motor will lose its effect

Because the rotor part of the motor itself is a magnet, the magnetic motor that is magnetized is magnetic and has high magnetic field will change the magnetic field of the rotor or eliminate part of the magnetic motor will not work properly.
