AST Motor is a new type of high-performance motor that incorporates a coil developed with our unique layering technology called AST COIL. We have succeeded in forming the coil, which used to be wound with copper wire, with sheet copper or aluminum. This has resulted in an overwhelmingly high occupancy rate, enabling dramatically higher efficiency, higher output, smaller size, and lighter weight. At the same time, this innovative technology has dramatically improved recycling efficiency. AST Motor has acquired the IP67 and has achieved robustness and long life that can withstand harsh flights.
