对一种具有双定子的盘式永磁同步电机进行了讨论、分析与试验验证。双定子电机因其具有的高转矩密度、控制灵活等特点受到了越来越多的关注,然而在实际应用中,如何进行双定子的能量分配以使系统效率最优也成为了一个难点。因此,提出一种基于MAP图的转矩分配策略,并在以TMS320F28335为主控芯片的试验平台上对电机进行了试验验证。试验结果表明所提出的控制分配策略能有效地保证双定子电机系统高效运行。

A disk permanent magnet synchronous motor with two stators was discussed, analyzed and verified by experiments. Doublestator motor had attracted more and more attention due to its high torque density, flexible control and other characteristics. However, in practical applications, in order to optimize the efficiency of the system, it was difficult to distribute the doublestator motor’s energy. A torque allocation strategy based on MAP diagram was proposed, and experiments were carried out on the experimental platform with TMS320F28335 as the main control chip. The experimental results showed that the proposed control and allocation strategy could effectively ensure the efficient operation of the doublestator motor system.
