Beschreibung
Zusammenfassung:	The utility model discloses a three-phase brushless motor control circuit, a three-phase brushless motor and a sputum excretion machine, and relates to the field of motor control. A controller and a three-phase power supply control module are arranged, and the three-phase power supply control end of the controller is connected with the control end of the three-phase power supply control module; the power supply input end of the three-phase power supply control module is connected with a three-phase power supply, the power supply output end of the three-phase power supply control module is connected with the power supply input end of the three-phase brushless motor, and the controller is used for controlling the number of power supply phases output by the three-phase power supply control module to the three-phase brushless motor so as to control rotation of a rotor of the three-phase brushless motor. The three-phase brushless motor is adopted, rotation of the rotor of the motor is controlled by controlling the
