“…Hence, magnet is chosen with flux density of around 0.2-0.4 T. It is better to increase the wire thickness and decrease the air gap flux density in order to reduce copper and eddy current losses. The generator outer diameter should not exceed 10 to 15 % of the blade diameter [9]. There are different parameters which affects output of the generator at the particular speed.…”

Abstract. This paper presents the modeling and design of a 3 kW Permanent Magnet Synchronous Generator (PMSG) used for a variable speed wind turbine. Initially, the PMSG is modeled in the d-q reference frame. Different optimized parameters of the generator are extracted from the design and used in simulation of the PMSG. The generator output power is matched with the power of the turbine such that the generator is not either over-sized or undersized.

In the paper the radial and axial permanent magnet synchronous machines (RPMSM, APMSM) are classified in accordance with the types of design topologies and degree of active electromagnetic materials utilization. To realize an express comparison analysis of these machines the generalized geometric method is presented. Unlike the other methods this approach is distinguished by very small time for calculation of the ratio of radial and axial machines volumes as well as the similar ratio of mechatronic modules based on these machines. Derived a simple analytical expression enables to draw 3D plot of the volume ratio of compared machines at different number of poles and various geometrical sizes. The comparative study shows, that at the increased number of poles and at certain stator and rotor configuration the APMSM confidently exceed the RPMSM in term of torque/power density.

“…To eliminate these shortcomings, it is advisable to use multipole permanent magnet synchronous machines (SMPMs) and axial magnetic flux in the air gap. Due to the low rotational speeds of these machines, one can create direct-drive (i.e., gearless) and highly reliable turbogenerator modules with minimal weight and dimensions [1][2][3] by using multipole synchronous hydrogenerators at hydroelectric power stations. Multipole permanent magnet synchronous machines made of rare-earth materials are now beginning to be applied for the creation of contactless power generation systems [4].…”

The paper deals with problems of selection of structures and optimum design of multipole permanent magnet synchronous machines (PMSMs) for operation in offshore wind-and wave-power plants under severe conditions for maintenance service. It is shown that multipole PMSMs are a new and very suitable electrical machine for direct connected turbogenerators in power plants and, at the same time, multipole PMSMs meet a number of other important demands, including high reliability, contactless construction, high efficiency, minimum mass and dimensions, and cost effectiveness. With the aim of systematization, an integrated classification scheme of PMSMs is presented to describe the variety of designs of stator and rotor configurations. With the help of a theoretical analysis based on a geometrical approach, analytical expressions for PMSM comparison are derived using the relationship between the criterion of optimization (maximum power density) and the main geometric parameters of PMSMs. Comparative analysis of the PMSMs with radial and axial magnetic fluxes for the case of various numbers of poles and different diameters of rotors has confirmed that axial multipole PMSMs are synchronous machines with maximum power density and an optimum variant for direct connected turbogenerator structures for offshore wind-and wave-power plants. It is noted that the advantage of axial PMSMs over radial PMSMs is monotonic growth in accordance with increasing number of poles p. Under the condition that p ≥ 20, which is strictly necessary for designing direct connected turbogenerators in offshore wind-and wave-power plants, we have more than doubled the power density at axial PMSMs as compared with radial ones.
