Abstract

The invention discloses a split type brushless motor, which comprises a stator component and a rotor component, wherein the stator component and the rotor component are split, are horizontally arrayed and coaxially arranged; the stator component is arranged in a stator housing; the stator component comprises a stator; a plurality of windings are arranged on the stator; the rotor component is arranged in a rotor housing; the rotor component comprises a rotor; the rotor is a permanent magnet with magnetism. According to the split type brushless motor, the rotor component and the stator component provided by the invention are arranged in a split-structure form, the noise of the split type brushless motor when in operation is reduced; besides, the split type brushless motor is suitable for various environments; meanwhile, the rotor component and the stator component are not in contact with each other, so that the rotor component and the stator component and other parts are not liable to damage, so that the service life of the motor is prolonged.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a split type brushless motor. Background technique [0002] A motor is an electromagnetic device that converts or transmits electrical energy according to the law of electromagnetic induction, or converts one form of electrical energy into another form of electrical energy. According to the law of electromagnetic induction, the magnitude of the magnetic induction of the coil affects the efficiency of the conversion or transmission of electric energy. At present, the structure of the split brushless motor mostly includes a stator and a rotor. The rotor is usually set in the middle of the space surrounded by the stator, and there is also a split brushless motor with the rotor set outside the stator; There is friction between the motor, the rotor and the stator, which makes the noise loud. [0003] In view of the above technical problems, those skilled in the art have designed ...
