# How do you control the speed of a DC motor fan?

## How do you control the speed of a DC motor fan?

DC voltage control is the method to vary DC fan speed and this can be implemented by incorporating resistances in the supply wire. The voltage drop across the series resistor reduces the voltage reaching the fan supply pin, automatically slowing the speed of the fan.

## How do you wire a DC motor speed controller?

To wire up a DC speed controller, you connect the motor power cables to the motor screw terminals on the controller, and the battery wires to appropriate battery screw terminals on the controller. Be mindful the wires are being gripped firmly and none of the wire strands have gotten loose and are sticking out.

What is diverter resistance?

Field diverter: A variable resistance is connected parallel to the series field as shown in fig (a). This variable resistor is called as a diverter, as the desired amount of current can be diverted through this resistor and, hence, current through field coil can be decreased.

### How do you make a motor controller circuit?

### How does a fan speed controller work?

The idea behind a capacitor regulator remains the same, which is to adjust the voltage across the motor of the fan. Now, when you increase the capacitance, the voltage across the capacitor decreases but that across the fan motor increases. Accordingly, the speed of the fan increases.

What is Ward Leonard method?

Ward Leonard method of speed control is used for controlling the speed of a DC motor. It is a basic armature control method. This control system is consisting of a DC motor M1 and powered by a DC generator G. In this method the speed of the DC motor (M1) is controlled by applying variable voltage across its armature.
