Magnetic component, motor and ceiling fan comprising motor

Abstract

The invention is suitable for the technical field of a motor and discloses a magnetic component, a motor and a ceiling fan comprising the motor. The magnetic component is a rubber magnetic ring, and a magnetic induction line of the rubber magnetic ring is bias arranged relative to an axis of the rubber magnetic ring. The motor comprises a stator component and a rotor component, wherein the stator component comprises a spindle and a stator iron core fixedly sleeved on the spindle; the rotor component comprises a shell part and the magnetic component arranged in the shell part; the magnetic component is the rubber magnetic ring; and the magnetic induction line of the rubber magnetic ring is bias arranged relative to the axis of the rubber magnetic ring. The ceiling fan comprises the motor. In the magnetic component, the motor and the ceiling fan comprising the motor provided by the invention, the rubber magnetic ring, of which the magnetic induction line is bias arranged relative to the axis of the rubber magnetic ring, is arranged, so that a stall torque and a torque pulse of the motor are greatly reduced, the running of the motor is stable and the reliability is high.

Description

technical field [0001] The invention belongs to the technical field of electric motors, and in particular relates to a magnetic component, a motor and a ceiling fan including the motor. Background technique [0002] At present, for motors in products such as ceiling fans, the magnetic components on the rotor are a plurality of arc-shaped magnetic tiles with a predetermined thickness and are annularly distributed outside the stator. The inner side of the ring; the magnetic components in the prior art are mostly permanent magnets such as sintered ferrite and neodymium iron boron, which are hard in texture and difficult to manufacture and install; and the permanent magnets generally use radial magnetization, and the motor runs during There is a large locked-rotor torque and torque ripple. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to overcome the above-mentioned deficiencies of the prior art, and to provide a magnetic component, a motor and a c...
