(cont) much lower in the conductor, the magnetic  field  changes  so  that  it spends the maximum distance in the conductor. This causes the lines of magnetic force to move so they pass through the conductors in the stator. As these magnetic lines of force move across the conductors, they generate the output voltage. The output voltage depends on the number of lines per second of magnetic field that move across the conductors. By controlling the speed of the generator (the rate at which the lines move) and the strength of the field (the number of lines), the output  voltage  is  controlled. This is the method used on brushless gener- ators.   As shaft and rotor speed increase, alternating current   is produced and flows from the stator housing  through  diodes  mounted  in  the rectifier plate. The diodes and rectifier plate change the alternating current to pulsating direct current. The pulsating direct current then passes through a bus bar to the filter box where the pulses are removed from the pulsating direct current. The resulting current is then ready for use as starting power for aircraft. 5-2. GENERATOR  ASSEMBLY  MAINTENANCE. a. Installed Test.
