在本实施例中， 输入所述交直流高效节能电机的交流电是三相交流电。 所 述整流模块 101 用于在电动机模式下对输入所述交直流智能高效节能电机的三 相交流电源进行整流， 把交流电源转化为直流电源。 其中， 输入所述整流模块 101的三相交流电源为来自于公共电网的工频 50Hz/60Hz三相交流电源，而所述 整流模块 101输出的电源是经过所述整流模块 101整流后的直流电源。 在本实 施例中， 所述整流模块 101 使用三相桥式全波整流电路实现对输入的所述三相 交流电源的整流， 把稳定的电源提供给本发明的交直流智能高效节能电机的其 他部分。
所述周期脉冲发生模块 102用于在电动机模式下在所述整流模块 101输出 的直流电源的激励下产生周期性脉冲信号源。 所述周期脉冲生成模块 102 的周 期性脉冲信号源是周期性方波信号源或者周期性正弦信号源， 并且要求所述周 期性脉冲信号源具有很好的频波稳定性。 在本实施例中， 所述周期脉冲发生模 块 102采用振荡电路连接周期性脉冲触发电路而实现。
所述速率调控模块 103用于在电动机模式下对由所述周期脉冲生成模块 102 产生的周期性脉冲信号源的速率频差进行调控。由于经过所述速率调控模块 103 调控的周期性脉冲信号源的速率频差决定了所述电机的转速， 所以所述速率调 控模块 103通过对所述周期脉冲生成模块 102产生的周期性脉冲信号源的速率 频差的调控实现了对所述电机的转速的调控。
所述速率调控模块 103对所述周期性脉冲信号的速率频差进行调控的过程 是对所述周期性脉冲信号的速率频差进行升高的过程或者是对所述周期性脉冲 信号的速率频差进行降低的过程。 对所述周期性脉冲信号的速率频差进行升高 的过程就是对所述周期性脉冲信号进行插值的过程。 图 3 示出了对所述周期性 脉冲信号的速率频差进行升高的过程。 参见图 3， 如果所述周期性脉冲信号源 301的周期是 T, 则所述速率调控模块 103在两个脉冲信号之间插入 N-1个等间 距的脉冲信号， 得到频速升高的周期性脉冲信号源 302。
对所述周期性脉冲信号的速率频差进行降低的过程是对所述周期性脉冲信 号进行降采样的过程。 图 4示出了对所述周期性脉冲信号的速率频差进行降低 的过程。 参见图 4， 如果所述周期性脉冲信号源 401的周期是 T, 则所述速率调 控模块每经过 N X T的时间段时对所述周期性脉冲信号源进行一次采样发生， 经 过采样得到的频速降低的周期性脉冲信号源 402就是所述速率调控模块 103的 输出信号源。 在本实施例中， 所述速率调控模块 103 采用按序电路连接触发器 电路来实现。
所述激励推动模块 104用于在电动机模式下对所述速率调控模块 103调控 后的周期性脉冲信号源进行控制， 并生成三相相互之间相位差相等的周期性信 号源。 经所述速率调控模块调控后的周期性脉冲信号源为周期性方波信号源。 所述激励推动模块 104首先对所述调控后的周期性方波信号源进行控制， 即将 所述调控后的周期性方波信号源的幅度进行电位变化。 随后， 所述激励推动模 块 104将所述周期性方波信号源分为八路进行处理， 具体是对八路周期性方波 信号源综合为四路正弦交流信号源进行阶梯工作。 所述将八路周期性方波信号 源综合为四路正弦交流信号源的过程是按照所述八路周期性方波信号源的频速 及上升沿下降沿的时间点对所述八路周期性方波信号进行综合。 所述四路正弦 交流信号源中的前三路正弦交流信号源按序相互之间具有相等的相位差， 而第 四路正弦交流信号源是前三路正弦交流信号源的综合点信号源。
所述功率驱动模块 105用于在电动机模式下对所述激励推动模块 104输出 的正弦波信号源进行功率调控。 所述功率驱动模块 105采用电源功率驱动器对 所述激励推动模块 104输出的正弦波信号源进行功率调控。 经过所述功率驱动 模块 105 的功率放大后， 所述正弦波信号源具有足够的功率， 能够推动所述电 动机的转子转动。
