Description

Industrial large fan with inner rotor type motor and lighting lamp
Technical Field
The invention relates to the technical field of fans, in particular to an inner rotor type motor industrial large fan with a lighting lamp.
Background
The driving motor of the ceiling fan products on the market at present is generally divided into an outer rotor type and an inner rotor type. The outer rotor type motor has a structure in which a motor shaft is not rotated as a motor stator and a motor housing is rotated around the motor stator as a motor rotor. And the inner rotor type motor is just the opposite.
In practice, illumination is often required in areas covered by the diameter of the fan blades. However, if the lighting fixture is installed above the ceiling fan, the rotation of the fan blades will generate a shadow that rotates back and forth under the ceiling fan, which seriously affects the user experience. The current treatment methods for this problem mainly include the following two methods: 1. the lamp originally installed above the ceiling fan is moved to the outside of the diameter coverage range of the fan blades of the ceiling fan. This reduces the effect of fan blade shadows on the user, but the illumination is not within the original central range, and thus the illumination effect is greatly reduced. 2. The illumination is realized on the outer rotor type motor ceiling fan. When the outer rotor type motor ceiling fan needs to be provided with the lighting lamp at the bottom, the lamp can be directly fixed on the non-rotating motor shaft, the lead of the lamp can be wired through the hollow structure in the motor shaft, and the rotation of the motor cannot influence the lead.
However, for the ceiling fan with the inner rotor type motor, the motor shaft is connected with the motor rotor, so that the motor shaft always rotates in the operation process of the motor, the lamp cannot be directly installed and fixed on the motor shaft of the inner rotor type motor, a lead of the lamp cannot be directly wired through the inside of the motor shaft, and otherwise the lead of the lamp can be damaged. Therefore, the ceiling fan with the inner rotor motor cannot be provided with a lighting lamp at the bottom of the ceiling fan at present, and the application range of the ceiling fan is severely limited.
