The suspension magnetic force of electro-permanent magnets features strong nonlinearity, which is closely related to the magnet structure. The existing analytical calculation formula for magnetic force of the hybrid magnet ignores the influence of magnetic circuit leakage and some other factors, consequently resulting in big errors in actual calculations. To solve this problem, two common hybrid magnetic circuit models are established to analyze the influence of edge magnetic flux distribution and magnetic circuit leakage on the working magnetic circuit of the magnet. On this basis, the magnetic circuit equations and related reluctance of the two hybrid magnets are deduced, and a corrected calculation method of the hybrid ferromagnetic force is put forward. Finally, the corrected magnetic force of the hybrid magnets with the two structures is verified by finite element analysis. The results show that due to the large suspension air gap, the influence of magnetic flux leakage of an electro-permanent magnet cannot be ignored in the calculation of electromagnetic force. Using the magnetic force correction formula proposed in this paper, the electromagnetic force errors of magnets with the above two hybrid structures are reduced to 3.8% and 8.3%, respectively.
