电机类型识别
摘要：
为了识别交流(AC)电机400的电机类型，首先将直流电(DC)施加到定子401以便将转子402的d轴与定子401的磁场方向对准。其次，在电流角度θ上将DC电流施加到定子401上，这导致永磁电机(PM)和同步磁阻电机(SynRM)的转子402在不同的方向上施以扭矩。检测转子402的扭矩方向406，并且基于扭矩方向信息来识别电机类型。根据扭矩方向406将电机类型识别为PM或SynRM。如果没有检测到扭矩，则将电机类型识别为感应电机(IM)。
摘要（英）：

For identifying the machine type of an alternating current (AC) machine (400), a direct current (DC) is first applied to the stator (401) for aligning the d-axis of the rotor (402) and the magnetic field direction of the stator (401). Secondly, a DC is applied to the stator (401) at a current angle q which causes the rotors (402) of a permanent magnet machine (PM) and a synchronous reluctance machine (Syn RM) to exert torque in different directions. The torque direction (406) of the rotor (402) is detected and the machine type is identified based on the torque direction information. The machine type is recognized as a PM or a Syn RM depending on the torque direction (406). If no torque is detected then the machine type is recognized as an induction machine (IM).
