Solar fan adopting 12V direct current motor

Abstract

The invention discloses a solar fan adopting a 12V direct current motor. The solar fan comprises a fan main body and a solar cell, wherein the fan main body comprises a shell, fan blades and a three-phase brushless direct current motor; the three-phase brushless direct current motor drives the fan blade to rotate, is directly connected with the solar cell by a lead, and comprises a rotor and a stator core; multiple groups of teeth with the same size are uniformly arranged on the periphery of the stator core, the number of the teeth is an integral multiple of three and is not less than six, three-phase windings are alternatively arranged on the teeth of the stator core, a winding coil is arranged on each tooth, and each phase of winding is formed by connecting the same-phase winding coils distributed on at least two teeth in parallel. The solar fan adopts the 12V driven three-phase brushless direct current motor as power, can be directly connected with the solar cell, and does not need a booster, so the solar fan is energy-saving and environment-friendly and reduces the manufacturing cost, and the weight of the fan is reduced.

Description

technical field [0001] The invention relates to a solar electric fan using a 12V DC motor. Background technique [0002] As a new energy source, solar energy has the advantages of being non-polluting and inexhaustible, and can be directly developed and utilized without mining and transportation. In contemporary times, the traditional energy is showing a trend of depletion, and the development and utilization of solar energy has been paid more and more attention by people. In some developing countries with energy shortages, solar energy has even entered ordinary households and been widely used. [0003] Existing small solar panels for households generally convert solar energy into 12V electric energy, while the working voltage of low-voltage motors used in existing electric fans is generally 24V. When using solar cells for power supply, a booster device is required to The 12V voltage is increased to 24V, which increases the manufacturing cost and the weight of the electric ...
