引用凤凰电调FAQ的话:
The spark is your friend。
如果没火花了,说明电容废了。电调也就快了,因为工作电压不再受到电容的稳定作用。
每个玩家有不同的喜好,有的玩家就是喜欢上电时“啪”的一个火花,来劲!
但是上电时火花会渐渐损伤插头,导致接触不良,然后可能引发其他所谓的“灾难性”问题。以下的说法也是凤凰电调的工程师在论坛上发表的:
The engineer says:
One of the most common causes of catastrophic failures in ESCS is using inadequate batteries or inappropriate plugs (too high resistance) between the battery and the ESC. Sizing batteries based on battery company’s claims of continuous current output is risky at best. It is always better to have at least 25% more capacity than you think you will need for a specific application. Inadequate or stressed batteries create excessive ripple current. The capacitors on the end of the ESC are there to handle ripple current. If there is too much ripple the capacitors become drained then overheat and either burn their leads, melt themselves off the board or explode. Once this occurs the ripple current cascades through the power boards burning the FETS. In the picture here the capacitors obviously melted off leading to the possible conclusion that ripple current destroyed this ESC.
所以,如果不用消火花电路,最好经常检查电池和电调的接头以免出现故障。
