Ceiling Fan Regulator Circuit Motor Speed Controller

This is a simple ceiling fan regulator circuit diagram tutorial. It is used to control the speed of a ceiling fan. In the other words it is an AC motor speed controller circuit, as because its control the speed of a AC motor(Ceiling Fan). This ceiling fan regulator circuit built with few numbers of parts. The circuit mainly based on Z0607 TRIAC. This is a low power AC semiconductor device. Generally which is used to controlling speed of low power ac motor speed.

Circuit Diagram of Ceiling Fan Regulator :

In this ceiling fan regulator circuit, R1=500KΩ is a variable resistor that is used to adjust the fan speed. Capacitor C1 2A104J is a Polyester film capacitor.

Parts List Of Ceiling Fan-Motor Speed Controller circuit:

T1 = Z0607 -TRIAC
D1 = DB3 C312 -DIAC
R1 = 500KΩ -Variable Resistor
R2 = 37KΩ -Resistor
C1 = 2A104J -Polyester film capacitor.
M1 = Single Phase AC Motor (Ceiling Fan)-220V,50Hz

Rotative Speed Regulator Borer Driller Controller

This rotative speed regulator schema schematic allows to control the holing speed of your borer or driller machine. This project is based on the fact that if the load grows, the voltage decrease and current increase. Use this schema to control the speed of revolutions of your drilling mill or bench drill.

PWM motor speed controller

This schema is designed as per a request made by Mr Vinoth from India. His requirement was a 12V/5A DC fan motor controller. I think this schema is sufficient for this purpose. Quad 2 input Schmitt trigger IC CD4093 is the heart of this schema. Out of the four Schmitt triggers inside the 4093, U1a is wired as an oscillator with adjustable duty cycle. The U1b, U1c, U1d buffers the output of the oscillator to drive the switching MOSFET Q1.The MOSFET drives the DC motor according to the switching pulse obtained from the oscillator. When R1 is varied the duty cycle varies and so do the speed of the motor. Diode D3 acts as a freewheeling diode.

Notes.

* Assemble the schema on a good quality PCB.
* IC U1 should be mounted on a holder.
* U1a, U1b, U1c, U1d are part of the same IC CD4093; so power supply is shown connected only once.
* The12V power supply for this schema must be able to handle at least 5A.
* A heat sink is recommended for Q1.
