Product overview A compact threephase permanent magnet synchronous generator designed for quiet, efficient indoor demonstration and lightpower applications. The unit delivers 3phase AC power with a brushless design for reliable operation and low maintenance. Key benefits Quiet operation for shared indoor spaces: Runs at about 36 dB, lower than typical household appliances, so it minimizes disturbance in classrooms, offices, and labs. Efficient power conversion: 20 W rated power across 1 to 15 V output and PVC blades tuned for conversion efficiency, providing stable output for demonstrations and small projects. Durable, lowmaintenance construction: Antirust aluminum alloy housing and UVresistant PVC blades extend service life while keeping weight low. Portable and easy to store: Compact footprint of 42 x 22 x 9 cm and 690 g weight makes it easy to transport and place on desks or shelving. Simple handson assembly: Blades unpacked; install by twisting screws for a quick DIY setup that supports learning and experimentation. Key specifications Type: Threephase permanent magnet synchronous generator (no carbon brush) Output: 3phase AC Rated power: 20 W Voltage range: 1 to 15 V Blade material: UVresistant PVC Housing material: Antirust aluminum alloy Noise level: Approximately 36 dB Size: 42 x 22 x 9 cm (16.53 x 8.66 x 3.54 in) Weight: 690 g Why customers need it Provides a reliable, lownoise demonstration generator for education and research without the maintenance concerns of brushed motors. Offers a realworld, handson component for teaching about electromagnetism, power conversion, and generator operation. Supplies a compact, efficient power source for small models and indoor displays where noise and durability matter. What makes it stand out Brushless threephase permanent magnet design for smoother output and longer life. Low acoustic signature and antivibration design tailored for indoor use. UVresistant PVC blades plus antirust aluminum alloy body combine durability with light weight. Practical applications and scenarios Classroom demonstration: Use as a teaching aid to show generator principles, AC output characteristics, and handson assembly skills. Laboratory or hobby projects: Integrate into smallscale experiments or modelmaking where controlled, lownoise AC power is required. Office or indoor display: Drive a gentle demonstration breeze for decorative models or informational displays without distracting coworkers. Assembly and use tips Blades are detached for safety and compact packaging. Install by aligning and twisting the fixing screws until secure. Designed to start with a gentle breeze for demo use; avoid excessive force during initial spin to protect bearings and blades. Mount on a stable, flat surface to take advantage of the antivibration design and maintain the low noise level. This generator is suitable for educational, experimental, and decorative indoor applications that require a compact, quiet, and durable threephase AC power source.
