Specifications: Product Name: Micro Wind Turbine Product material: PAC material Product speed: 100-600 rpm Product specifications: as shown in the picture above Product sheets: 3 pieces Product power: 1-25W Product voltage: 1-15V Product weight: 520g Characteristics: Vertical generator Use brushless DC motor, no carbon brush, maximum power 25W The brushless motor has no brush, so there is no electrical spark when the brushed motor is running, reducing the impact on the power tool. Second, when the brushless motor is running, the friction force is greatly reduced, the operation is smoother, and the noise is lower. Generator installation: Body and Shaft The motor main body and shaft are integrated with the PAL material to encase the motor, so the generator life is longer The base is a triangular bracket, easy to install and fix Blade Adopt the popular 3D printing PAL material design, with high conversion efficiency, corrosion resistance and UV resistance Due to the inconvenience of packaging the product, it is packaged separately and the triangular base is screwed into the bottom of the generator upon receipt.
