brush current
中文解释：“brush current”通常指的是在电化学或电子学中，当刷子（如碳刷）与旋转部件接触时产生的电流。它也可以指在某些机械系统中，通过摩擦或接触产生的微小电流。
英文解释："Brush current" refers to the electric current that flows when a brush, such as a carbon brush, makes contact with a rotating component. It can also refer to a small current generated through friction or contact in certain mechanical systems.
使用场景：常见于电机、发电机、直流设备等场合，用于描述刷子与换向器之间的电流现象。
相关术语：carbon brush, commutator, electric motor, DC system
例句：在直流电机中，刷子与换向器之间的接触会产生 brush current，这是正常工作的一部分。
例句翻译：In a DC motor, the contact between the brush and the commutator generates a brush current, which is part of normal operation.
