技术介绍
永磁电机与电励磁电机相比，具有体积小、效率高、工作可靠、制造方便等优点，但 也存在一处显著的缺点磁场强度不可调整。在发电机应用领域，当转速或负载发生变化 时，发电机的输出电压将随之产生波动，如风力发电机，风速的变化将直接影响电机转速， 负载也会从空载变化到满载，从而造成输出电压很大的波动。电励磁发电机可采用调节励 磁电流的方式，来改变磁场强度，达到稳压的目的。但对永磁发电机来讲，磁场强度不可调 整，现有的技术大多采用通过外部电子调压的方式来稳压，不仅成本很高，并增加许多不可 靠因素。在电动机应用领域，当电压或负荷发生变化时，电动机的输入电流将随之产生较大 波动，如车用电动机，在行驶中需要不断地改变电动机的转速与转矩，并希望转速与转矩调 节范围尽量大些，电励磁电动机可采用调节励磁电流的方式，来调节磁场强度，增加磁场强 度可以降低转速、提高转矩，减小磁场强度可以提高转速、降低转矩，从而适应车辆行驶的 需要。但对永磁电动机来讲，磁场强度不可调整，其转速与转矩特性是相对固定的，...
