An annular linear induction electromagnetic pump having axial guide vanes is provided. m axial guide vanes are uniformly arranged in a flow channel of the electromagnetic pump in a circumferential direction, and a magnitude of m is equal to a number of external stators. A length of each of the guide vanes is precisely determined by a parameter P, and the value of the parameter P is calculated together by the number of the external stators, a central radius of the flow channel, a magnetic Reynolds number, a wave number of a traveling magnetic field and the mean fluid velocity. The axial guide vanes can significantly mitigate the impact on the flow field stability caused by uneven circumferential disturbances of the magnetic field and flow field, thereby achieving a flow stabilization effect with less hydraulic losses and greatly improving the flow stability in operation under off-design conditions.
