Aiming at the problem of long computation time of finite element analysis (FEA) and poor calculation universality of existing analytical models, this paper proposes a general hybrid analytical model to predict the no-load and load performance of interior permanent magnet motors, where the form of magnet can be V-shape, U-shape or flat-shape. The magnets are equivalent to facilitate the establishment of subdomains, and the no-load magnetic field of the motors can be obtained by solving the boundary equations and conformal mapping, where the nonlinear of core is calculated by MEC. Besides, a subdomain model considering armature reaction is adopted to obtain the load magnetic field, and calculate the torque characteristic of motors. The effectiveness of the proposed model is verified by both FEA and experiments. Compared with FEA, this model can consume less time with the acceptable accuracy, which brings convenience to the design and optimization of related types of motors.
