One solution is to add a rotor position sensor to the synchromotor. 解决这一问题普遍的做法是加装电机转子位置传感器。
The engine operation signals as well as the engine speed can be measured by trigger cam of the crankshaft position sensor and sensor that are installed on the crankshaft axis. 发动机信号同步发动机转速通过安装在曲轴轴线上的曲轴位置传感器触发轮及传感器进行测量。
