本文从理论上介绍并开发了一种新的同步磁阻电机（SynRM）运行图（OPD）和参数估计器。 OPD 在一张图表中展示了机器主要性能参数的行为，例如扭矩、电流、电压、频率、磁通、功率因数 (PF) 和电流角。该图可以轻松地用于描述不同的控制策略、可能的操作条件、低于和高于额定速度等。还通过有限元方法计算用该图讨论了饱和效应。设计了高性能 SynRM 原型用于实验研究，然后测试、测量和比较两台机器 [相应的感应电机 (IM)] 在相似负载和操作条件下的性能，以展示 SynRM 的潜力。实验室测量（在标准 15 kW Eff1 IM 及其对应 SynRM 上）表明，在相同绕组温升条件下，与 IM 相比，SynRM 具有更高的效率、扭矩密度和逆变器额定值，以及更低的转子温度和 PF。测量结果表明 SynRM 的扭矩能力与 IM 非常接近。
This paper theoretically introduces and develops a new operation diagram (OPD) and parameter estimator for the synchronous reluctance machine (SynRM). The OPD demonstrates the behavior of the machine's main performance parameters, such as torque, current, voltage, frequency, flux, power factor (PF), and current angle, all in one graph. This diagram can easily be used to describe different control strategies, possible operating conditions, both below- and above-rated speeds, etc. The saturation effect is also discussed with this diagram by finite-element-method calculations. A prototype high-performance SynRM is designed for experimental studies, and then, both machines' [corresponding induction machine (IM)] performances at similar loading and operation conditions are tested, measured, and compared to demonstrate the potential of SynRM. The laboratory measurements (on a standard 15-kW Eff1 IM and its counterpart SynRM) show that SynRM has higher efficiency, torque density, and inverter rating and lower rotor temperature and PF in comparison to IM at the same winding-temperature-rise condition. The measurements show that the torque capability of SynRM closely follows that of IM.
