The two different rotor structures have a large impact on the comprehensive performance in multiple physical fields of HSPMMs, including mechanical …Similar to type Ⅰ, this configuration also forms a series magnetic circuit between the inner stator, outer stator and rotor. The rotor structure of type Ⅲ is similar to that of type Ⅱ, but the magnetisation direction of the inner and outer PMs located on the same axis are opposite. In this rotor structure, the rotor yoke contains ...

Among them, the NS type rotor has a structure in which the permanent magnetization direction of the two-sided rotor is opposite. One rotor permanent magnet magnetic flux flow to the opposite rotor. The advantage is that there is no magnetic flux flowing through the Stator back-yoke, making the design easier. Furthermore, by …Coaxial counter-rotating propellers have been widely applied in ships and helicopters for improving the propulsion efficiency and offsetting system reactive torques. Lately, the counter-rotating concept has been introduced into the wind turbine design. Distributed wind power generation systems often require a novel approach in generator …(PMSM) into the market. Permanent magnet synchronous machines have been applied to servo drives for a long time already, and nowadays, there are quite large permanent magnet synchronous machines also in industrial use. In wind mill generators, the development has currently been in the direction of permanent magnet machines. This control method can control the AC permanent magnet servo motor as a DC permanent magnet motor in a sense. According to Equations (1)–(3), the second-order dynamic equation of the position ring of the PMSM is expressed as follows: (4) { θ ˙ = ω ω ˙ = b i q + d (4) where b = 1.5 p n ψ f / J is a disturbance composed of unknown friction …
