Abstract

The invention relates to a brushless DC motor output pulse converting circuit, and relates to the field of motors. Multi-pole motors are high in development cost and long in development period. The circuit comprises a chip IC1 with a built-in frequency conversion module, an output pulse circuit and a Hall sensing circuit, the chip IC1 is provided with an input terminal pin IN, an output terminal pin OUT, a grounding terminal pin GND and a terminal pin VCC, the input terminal pin IN is connected to the Hall sensing circuit to receive an input pulse, the terminal pin VCC is connected with a power supply VCC, the grounding terminal pin GND is grounded, and the output terminal pin OUT is connected with the output pulse circuit. The input pulse of the Hall sensing circuit is inputted into the chip IC1 through the input terminal pin IN, and then the converted industrially universal speed pulse frequency is outputted by the output pulse circuit through the frequency conversion of the chip IC1. The circuit has the advantages of simple structure and convenient conversion, can conveniently correspond to motors with different numbers of poles through corresponding to the position of a Hall sensor, greatly reducing the development cost and shortens the development period.
