Problems solved by technology

[0002] As a fan device, the ceiling fan is an indispensable item in the hot summer. The ceiling fans currently on the market are all single-ceiling fan structures with three to four blades, which have low air supply efficiency and large torque. In order to obtain a larger air volume, manufacturers generally solve the problem by increasing the size of the fan blades and the power of the motor. This will undoubtedly increase the consumption of motor materials and at the same time increase the energy consumption of the ceiling fan used, and the torque of the ceiling fan running at high speed It will increase, which in disguise increases the risk of the ceiling fan falling

Abstract

The invention discloses a coaxial opposite-rotation electric ceiling fan. The coaxial opposite-rotation electric ceiling fan comprises a first ceiling fan body, a second ceiling fan body, a coupler and a starting device. The first ceiling fan body comprises a first motor, a first machine shaft penetrating a stator of the first motor and fan blades connected with a rotor of the first motor. The second ceiling fan body comprises a second motor, a second machine shaft penetrating a stator of the second motor, and second fan blades connected with a rotor of the second motor. The first motor and the second motor are opposite in rotation direction. The coupler is used for connecting the first ceiling fan body with the second ceiling fan body which are arranged in advance into a whole. The starting device is arranged between the first ceiling fan body and the second ceiling fan body, and the first ceiling fan body and the second ceiling fan body are electrically connected with the starting device. According to the coaxial opposite-rotation electric ceiling fan, the air supply efficiency of the coaxial opposite-rotation electric ceiling fan can be improved, torque balance and loss reduction are achieved, a new platform is provided for electric ceiling fan appearance design, and the production speed of the coaxial opposite-rotation electric ceiling fan is increased on the premise that the existing ceiling fan motor manufacturing technology and dies are not overturned.
