PURPOSE:To obtain a pulse phase converter with a simple configuration by combining NAND gates and inverters. CONSTITUTION:The pulse of the first phase applied to the first input terminal 1 is amplified by the first amplifier 4, and applies a pulse current to the motor coil 5 of the first pole. The second and third phase pulses applied to the second and third input terminals 2, 3 are inputted to the first NAND gate 6. The output of the first NAND gate 6 and the third phase pulse applied to the third input terminal 3 are inputted to the second NAND gate 7. The output of the second NAND gate 7 is amplified by the second amplifier 8, and applies a pulse current to the motor coil 9 of the second pole. An inverter 10 inverts the polarity of the pulse of the first phase applied to the first input terminal 1, and the inverted pulse is applied to the motor coil 12 of the third pole via the third amplifier 11. Further, the pulse of the third NAND gate 13 is applied via the fourth amplifier to the motor coil 15 of the fourth pole. |
