Ceiling fan with speed regulating indicator light circuit

Published:2011/9/14 9:49:00 Author:nelly | Keyword: Ceiling fan, speed regulating, indicator light

Adding a working indicator light to the ordinary ceiling fan not only can display the speed regulating gears, but also can provide the weak light illumination for the room, as shown in the picture. L is the inductance coil; SA is the speed regulating switch; “1”～“5” are the air-speed gears; off means stop. H is the speed regulating indicator light, which is going to be added. It is the small light with 0.3A/6.3V, which can be added by serial connecting to the input.   (View)

Single-phase shading coil type motor reactive resistance speed regulating circuit

Published:2011/9/13 23:57:00 Author:nelly | Keyword: Single-phase, shading coil type, reactive resistance, speed regulating

As the picture shown, the reactive resistance is in series of motor, adjusting the regulating switch SA. When the key of “fast” is touched, the reactive resistance is not connected, and then the motor operates at full voltage, so the speed is the fastest; When the key “middle” is touched, some inductance coil will be serial, so the speed is intermediate; when the key of “slow” is touched, all the L coils are connected to the stator winding, so the speed of the motor is slowest.   (View)

Sub-ultrasonic fan speed regulating controller circuit

Published:2011/9/13 8:36:00 Author:nelly | Keyword: Sub-ultrasonic, fan, speed regulating, controller

Sub-ultrasonic fan speed regulating controller can control the switch and speed of the fan, and it also can control the other appliances. The emitting end applies the sub-ultrasonic emitter, which is the main feature of this device. It also has no limitation about direction, and it is durable and do not need power source. The sub-ultrasonic received by the piezoelectric buzzer is amplified by V1, frequency selected by L, C4, and then amplified by V2m. it outputs pulse. You can mold the emitter when operating. The collector V2 will output a positive pulse triggering signal which is counted by the decimalism counter CD4017. It applies the Q1, Q2, Q3 gears of CD4017.   (View)
