👉 Brushlessness is a concept in electronics and electrical engineering that refers to the absence of physical contact between an electronic component and its environment, such as wires or contacts. In other words, it describes how components like resistors and capacitors behave when they are not connected directly to another component. In essence, brushless motors operate by using brushes to dissipate heat instead of using a permanent magnet or electromagnet in their design. This allows them to have a lower power consumption than traditional直流电机，
