DC fans are usually rated for 5V, 12V, 24V or 48V. Most common is the 12V type. The rated operating voltage will make the fan spin at full speed. The most common way to adjust the speed of the fan is to adjust the supply voltage of the fan. Decreasing the supply voltage decreased ...

FIG. 5 is a schematic diagram showing a controller for generating drive signals for the coils; FIG. 6A is a two-dimensional view of the relationship between the sensor magnet and the sensor card; FIG. 6B is an end view of the rotor assembly and sensor card; and ...
Electricity enters the motor via the brushes (shown as graphite brush in the schematic). These brushes touch the commutator, which receives the electrical current and passes the voltage through copper wiring to the internal coils. The electromagnetic force pushes the core away from the North polarit...
