The generator of the MWT is made up of 26 poles and the number of revolutions was found in rpm (n = 60f /2P) depending on the frequency. The rotation variation and MWT power depend on the wind speed given in Fig.
The description of the information given in Fig. 1 is as follows: (a) the rotor spindle diameter, (b) the stator outer diameter, (c) the angle between poles, (d) the stator inner diameter, (e) the upper distance between the stator
The inner diameter, length of the stator and slot height were considered as the main shape parameters that influence both the active power and weight of the generator. Based on the results of the sensitivity analysis, a

One component that plays an important role in wind power generation systems is the generator. A generator is a machine that converts mechanical energy into electrical energy. In small scale wind power plants, permanent magnet synchronous generators (PMSG) are commonly used as energy conversion machines.
In other words, the wind turbine and the generator should have the same size. Building a prototype: This work has focused on optimisation of a PMSG and verifying its electromagnetic and thermal performance via FEM and lumped parameter modeling, respectively. The models have authenticated that the machine works according to the expectations.
The DC windings of the generator consist of 5 double pancakes, each of which has 1232 windings and a total of 12,320 windings. The geometric dimensions of the superconducting tapes constituting the windings are 12 mm × 100 μ and each tape is assumed to be covered with a 150 μm dielectric insulating material.
However, it would be interesting to consider the field weakening capability at the design stage. This requires a more accurate model of wind turbine torque speed diagram. When it comes to control of the machine, it is suggested that the torque trajectory of the wind turbine and the generator intersect each other in generator’s base speed.
Since the main objective is a compact design that will significantly reduce construction, transportation, and operating costs in sea-based wind plants, the condition for axial length and generator outer radius to be less than 2 m will be taken as a parameter . The fundamental design parameters are listed in Table 1.
12 poles, with a rotation speed of 500 rpm. The simulation test results obtained the following data, the output phase-phase maximum voltage of the generator is 38.84 V, and phase maximum voltage is 22.5 V. Wind energy is one of the primary energy sources that can be used to produce electricity.
