Definitions

  • US Patent No. 5541483 provides a method for controlling a direct current (DC) motor or generator, particularly those of the permanent magnet type. Due to functional differences between AC and DC generators, the described solution would not be operative for an AC generator.
  • DC direct current
  • Figure 7 illustrates in greater details a voltage regulation system and a rotation speed sensor, according to an embodiment of the invention
  • Figure 8 illustrates in greater details a voltage regulation system and a rotation speed sensor, according to an embodiment of the invention
