The invention provides a variable-phase modular stator bilateral switched reluctance linear motor. The variable-phase modular stator bilateral switched reluctance linear motor comprises a rotor; the fixed stator and the sliding stator are arranged on the two sides of the rotor respectively, and each of the fixed stator and the sliding stator comprises a plurality of U-shaped stator modules which are uniformly arranged; each U-shaped stator module comprises a stator magnetic pole and a coil winding wound on the stator magnetic pole; the sliding mechanism drives the sliding stator to be switched between a first position and a second position through linear motion; the motor power converter comprises a first excitation topological structure and a second excitation topological structure, and when the sliding stator is located at the first position, the motor power converter adopts the first excitation topological structure to be connected with the coil windings on the fixed stator and the sliding stator to realize m-phase operation; and when the sliding stator is located at a second position, the motor power converter is connected with the coil windings on the fixed stator and the sliding stator by adopting a second excitation topological structure to realize 2m-phase operation.
