在可再生能源发电机中，直接驱动功率起飞的设计往往侧重于力密度，自然导致使用相对昂贵的永磁电机。在工业领域的其他领域，感应电机传统上占据主导地位，因为它们成本低，性能强劲。在这项研究中，用于开放式中心潮汐涡轮机的发电机的设计作为一个案例研究，以直接比较感应和永磁电机。涡轮设计中的机械约束迫使发电机产生较大的磁隙，这固有地限制了功率密度和功率因数。从性能和经济性两方面对永磁设计和感应设计进行了比较。
Design of direct drive power take off in renewable energy generators tends to focus on force density, naturally leading to the use of relatively expensive permanent magnet machines. Elsewhere in the industrial landscape, induction machines traditionally rule as they are low cost and robust. In this study, the design of a generator for use in an open centred tidal turbine is presented as a case study to directly compare induction and permanent magnet machines. Mechanical constraints in the turbine design enforce a large magnetic gap in the generator, which inherently limits the power density and power factor. A comparison between the permanent magnet design and the induction design in terms of performance and economy has been presented.
