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.
