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.
