Abstract

The invention discloses a brushless DC motor for a soybean milk machine. The brushless DC motor comprises a main shaft, a rotor, a stator, a Hall structure, a driver and a case, wherein the rotor is installed on the main shaft, the stator is electrically connected with the driver, the installing position of the Hall structure matches the position of the rotor, and the main shaft, the rotor, the stator, the Hall structure and the driver are all installed in the case. The brushless DC motor functions depending on changes of a magnetic field between the rotor and the stator, and does not need a commutator and a carbon brush in the working process. Furthermore, the information of the rotor is returned by the Hall structure as feedback to enable the driver to control the electrifying sequence of the coil so that the main shaft can rotate. No mechanical friction exists, noise and dust caused by mechanical friction are removed, and the efficiency and service life of the motor are greatly improved. The brushless DC motor will not pollute the environment, enables a user using the soybean milk machine to get the better user experience, and is energy-saving and environment-friendly.

Description

Technical field [0001] The invention relates to the field of motor design, in particular to a DC motor for household soymilk machines. Background technique [0002] The small home appliances on the market, especially household soymilk machines, generally use DC brushed motors. DC brushed motors are motors composed of rotors, permanent magnets, commutators, and carbon brushes. The commutator contacts to change the energization sequence of the winding to realize the rotation of the motor. This kind of motor has mechanical friction between the carbon brush and the commutator when it is rotating, which will produce very loud noise and dust generated by the friction of the carbon brush. In addition, the friction between the carbon brush and the commutator will The power consumption reduces the efficiency of the motor and will seriously affect the life of the motor. The dust generated by friction will also cause secondary pollution to the food machinery. Summary of the invention [00...
