The invention discloses a slip frequency power control method of a linear motor, a maglev train, equipment and a medium, and the method comprises the steps: controlling a first doubly-fed linear motor and a second doubly-fed linear motor to generate different primary power supply frequencies, and then obtaining different slip frequency; on the premise that the first doubly-fed linear motor and the second doubly-fed linear motor are controlled to generate the needed synthesis driving force, a pair of balance force which is equal in magnitude and opposite in direction is controlled to be overlaid on the secondary level of the first doubly-fed linear motor and the secondary level of the second doubly-fed linear motor; and according to the slip frequency, adjusting the slip power of the first doubly-fed linear motor and the second doubly-fed linear motor by adjusting the balance force. According to the invention, the slip frequency power can be effectively controlled when the counter-acting force of the double-fed linear motor is insufficient.

    本发明公开了一种直线电机的滑差功率控制方法、磁浮列车、设备及介质,所述方法包括:控制第一双馈直线电机和第二双馈直线电机产生不同的初级供电频率,进而得到不同的滑差频率;控制第一双馈直线电机和第二双馈直线电机产生所需合成驱动力的前提下,分别控制第一双馈直线电机和第二双馈直线电机的次级上叠加一对大小相等且方向相反的平衡力;根据所述滑差频率,通过调节平衡力的大小,调节第一双馈直线电机和第二双馈直线电机的滑差功率。本发明能够在双馈直线电机反作用力不足时实现对滑差功率的有效控制。
