ADVANTAGE :
- Brushless synchronous generator:
+ Instead of using a brush, using a computer to control and help balance the speed of the electric motor should make the brushless motor more efficient
+ No noise and much less sparks
+ Because there is no brush in the structure, there will be no wear and tear due to friction.
With the electromagnets located on the stator they are easily cooled
+ You can use more electromagnets on the stator to control more accurately
+ Smooth operation (small torque oscillations)
+ High efficiency, power ratio, generator volume.
- Brushed alternator
+ The outstanding advantage of the brush generator is that it is cheap, the price of the magnet is quite cheap, but still gives outstanding product quality and meets all the needs of customers.
+ In addition, the brush in the motor has the function of transmitting current, supplying electricity and maintaining the rotor part due to contact and sliding on the motor commutator or slip ring of the generator part.
DEFECT :
- Brushless alternator:
+ Because brushless synchronous generators are excited from permanent magnets, the cost of permanent magnets is quite high, because the price of brushless synchronous generators is quite high, This is the only advantage of brushless alternator.
+But absolutely you can get good and durable working efficiency and longer than the life of a generator. If replaced with sharp magnets, they are easy to magnetize, but the magnetization capacity is not high, they are easily demagnetized, and the magnetic properties of the magnets are reduced with increasing temperature. Does not give the optimal quality as permanent magnets.
- Brushed alternator
+ The main cause is due to graphite brush, so only using it for a while will wear out the brush, poor life, large power consumption motor, weaker capacity than other motors of the same size.
+ Above is some clear information to help you distinguish the advantages and disadvantages of 2 types of brushless synchronous generators and brushless generators so that you can make the most suitable choices for your case. applied to work effectively.
