Parameters of PM machines, especially for IPM machine, are known to vary by significant amounts. This affects the controllability of such machines, which may lead to reduced power loading capability and increased losses. The present invention relates to a method for PM machine inductance profile identification based on voltage mode stator flux observation which could be easily integrated to the generator start-up process in wind turbine application for both stator flux vector feedback control system and current vector feedback control system.

Various systems and methods for forming a polymer part with utilizing heating fluid are provided. In one embodiment of the present invention a method for forming polymer includes heating the mold apparatus with a first heat energy source comprising heating fluid to a first mold temperature, and then heating the mold apparatus with a second energy source which is different than the first energy source. The second energy source heats the mold surface to a second mold temperature greater than the first mold temperature to form the part to achieve a desired surface finish of the polymer part.

A wind turbine is provided. The wind turbine includes a generator, an output thereof being connectable to a power grid via a power transmission path, the power transmission path comprising a generator side converter coupled to the output of the generator, a grid side converter coupled to the power grid, and a DC link coupled between the generator side converter and the grid side converter. For diverting the generator power, a load dump arrangement is provided which includes at least one resistor, a plurality of switches, and a plurality of electrical connections which electrically connect the at least one resistor to the output of the generator and across the DC link via the plurality of switches. One common and configurable load dump is used for both converter system failures and grid failures. As compared to two separate load dumps for converter failures and grid failures, the single load dump will require a smaller space for a wind turbine. Thus, the weight and size of the power converter system may be reduced.

Various mold apparatuses and methods for forming a polymer with induction heat energy are provided. In one embodiment of the present invention, a mold apparatus for forming polymer includes a mold having a top mold portion and a top mold surface that is magnetic. The bottom mold portion of the mold includes an induction heating unit that is at least partially embedded in the bottom mold portion that provides induction heat energy to the mold. The mold apparatus is constructed and arranged to dissipate greater than about 50% of the induction heat energy in the top mold portion. The induction heating unit of the bottom portion of the mold provides rapid heating to the top mold surface to provide high surface quality polymer parts and a shorter molding cycle time while utilizing less energy.
