About Alternator
Advantages of all copper brushless generators:
All-Cooper：
1. The all-copper generator is more durable.
2.Pure copper wire generators are more energy efficient.
3.Pure copper core generator is quieter.
Brushless：
1. Low interference: The brushless motor has removed the brush, and the most direct change is that there is no electric spark generated when the brushed motor is running, which greatly reduces the interference of the electric spark to the remote control radio equipment.
2. Low noise and smooth operation: The brushless motor has no brushes, the friction force is greatly reduced during operation, the operation is smooth, and the noise will be much lower. This advantage is a huge support for the stability of the model.
3. Long life and low maintenance cost:Without the brush, the wear of the brushless motor is mainly on the bearing. From a mechanical point of view, the brushless motor is almost a maintenance-free motor. When necessary, only need to do some dust removal maintenance.
