Abstract

PURPOSE:To maintain the revolution of a motor irrespective of the variation of its frequency by selectively shortcircuitting a resistor by a frequency change-over switch. CONSTITUTION:In the district where a power source frequency is 50Hz, a frequency change-over switch S5 is switched to ''50'' side. When a combustion switch S4 is shifted to ''HIGH'' side at the time of high combustion, all the resistors R1-R3 are shortcircuitted, a voltage V is applied to a motor M2 as it is, and the motor M2 will rotate at a rated speed. When the switch S4 is shifted to ''LOW'' side, the resistors R1, R2 are connected in series with the motor M2, and the motor M2 is decelerated. In the district where a power source frequency is 60Hz, the switch S5 is shifted to ''60'' side. In this case, the resistor R3 is always connected in series with the motor M2.
