对转永磁无刷直流电动机在舰船等的对转推进系统中有着较大的应用趋势和发展前景。基于普通永磁无刷直流电动机的数学模型,建立了对转永磁无刷直流电动机的数学模型,根据反电势三次谐波检测换相原理,使用MATLAB建立了对转永磁无刷直流电动机三次谐波检测系统的模型,对其进行了仿真验证,仿真结果表明基于三次谐波法的对转永磁无刷直流电机仿真系统模型正确可靠,三次谐波检测换相原理在对转电机中的应用是可行的,可进一步深入研究。
Counter rotating Permanent Magnet Brushless DC Motor (CRPMBLDCM) will be widely used in count- er rotating propelling systems of naval ships. Based on the mathematical model of common BLDCM, a mathematical model of CRPMBLDCM is constructed. According to the commutation principle of detecting the third harmonic back electromotive force (EMF), a simulation model of CRPMBLDCM using third harmonic back EMF is constructed in the MATLAB. This model is tested and the simulation result shows the validity of the model. Also, it shows that the commutation principle of detecting the third harmonic back EMF can be used in CRPMBLDCM. The simulation model can be used for further study.
