调速开关采用电子电路或微处理芯片去改变电机的级数、电压、电流、频率等方法控制电机的转速,以使电机达到较高的使用性能的一种电子开关。对交流电机而言,调速方式有:1)电感式调速,2)抽头式调速,3)电容式调速,3)可控硅调速,4)变频式调速。对直流电机而言,调速方式有:1)电枢回路电阻调速,2)电枢电压调速,3)晶闸管变流器供电的调速,4)大功率半导体器件的直流电动机脉宽调速,5)励磁电流调速。
开关与灯具控制顺序相对应,风扇的转向及调速开关应正常。
Switch should match sequence of lighting fixture control. Direction turn and speed regulating switch of fan should work well.
