To solve the problem that the propulsion motor of the solar-powered aircraft is difficult to meet the high-torque-density requirement. the mass optimization method of a surface-mounted permanent magnet synchronous motor (SPMSM) based on a lightweight structure is proposed in this paper. According to the motor load generated by propeller. the strength and stiffness analytical models of... https://www.roneverhart.com/Castello-di-Amorosa-Il-Barone-Napa-Valley-Cabernet-Sauvignon-2007/
