Problems solved by technology
[0002] At present, vacuum cleaners include AC corded vacuum cleaners or DC cordless vacuum cleaners. AC corded vacuum cleaners usually require a long power cord to ensure a large enough cleaning area, so it will cause inconvenience to users for actual use; DC cordless vacuum cleaners overcome The disadvantages of AC corded vacuum cleaners, but because their motor power is smaller than that of AC motors, DC cordless vacuum cleaners will be inferior to AC corded vacuum cleaners in terms of service life and dust removal capacity.
[0003] Moreover, AC corded vacuum cleaners widely use series motors, which have the disadvantages of short life, high noise, low efficiency, large starting torque, low power factor and strong electromagnetic radiation interference.
DC brushed motors or brushless DC motors are widely used in DC cordless vacuum cleaners. DC brushed motors have a short service life and sparks when working. It is restricted, which limits its application in the current development trend of high power, high speed, and high suction of vacuum cleaners; although brushless DC motors are the development trend of current applications, they cannot automatically adapt to high-voltage DC and low-voltage DC, and low-voltage applications The brushless DC motor of the high-voltage application will not be able to reach the best working area of the motor under high-voltage conditions, and it will not be able to give full play to the advantages of the motor itself. Similarly, the brushless DC motor for high-voltage applications will not be able to achieve the best work of the motor under low-voltage conditions. area, and cannot give full play to the advantages of the motor itself

The invention provides a vacuum cleaner and a vacuum cleaner motor control system. The vacuum cleaner motor control system comprises: a power supply circuit, wherein the power supply circuit comprisesa first power supply unit and a second power supply unit, the input end of the first power supply unit is connected with a first power supply and the input end of the second power supply unit is connected with a second power supply; a motor comprising a first stator winding and a second stator winding; a power supply detection circuit, wherein an input terminal of the power supply detection circuit is respectively connected with a first power supply unit and a second power supply unit; a driving circuit whose output terminals are respectively connected with the first stator winding and the second stator winding; a control circuit has an input terminal connected to a power supply detection circuit and an output terminal connected to a driving circuit. The motor control system of the vacuumcleaner can support different power supplies to the vacuum cleaner, improves the applicability of the vacuum cleaner, drives the first stator winding or the second stator winding arranged on the stator according to the power supply type, and ensures that the motor is in the best working condition.
Description
technical field [0001] The invention relates to the technical field of electrical appliances, in particular to a vacuum cleaner motor control system, a vacuum cleaner and a vacuum cleaner motor control method. Background technique [0002] At present, vacuum cleaners include AC corded vacuum cleaners or DC cordless vacuum cleaners. AC corded vacuum cleaners usually require a long power cord to ensure a large enough cleaning area, so it will cause inconvenience to users for actual use; DC cordless vacuum cleaners overcome AC corded vacuum cleaners have disadvantages, but because their motor power is smaller than that of AC motors, DC cordless vacuum cleaners are inferior to AC corded vacuum cleaners in terms of use time and dust removal capacity. [0003] In addition, series-excited motors are widely used in AC corded vacuum cleaners, which have the disadvantages of short life, high noise, low efficiency, large starting torque, low power factor and strong electromagnetic radi...
