Compared with conventional electric machines, the dual mechanical ports electrical machine had more energy conversion modes and great potentials used in hybrid electric vehicle. However, the two shaft extension parts of the dual mechanical ports electrical machine were connected to different loads, so the conventional optical encoder could not be used. Therefore, magnetic reluctance resolver with good robustness was choosed as the speed sensor. This paper analysed the principle of magnetic reluctance resolver, then the excitation circuit and decoding circuit were designed based on AD2S1200. At last, the experiment results proved the correctness and rationality of the design.
