A new permanent magnet arc guideway motor is put forward, which can directly drive load for reciprocating motion within a limited angle and is provided with advantages of simplification, reliability, high efficiency, etc. The permanent magnet deflection angle is parameterized and the influence on electromagnetic force has been analyzed between different magnetization and electrifying modes： Results show that resultant of magnetic force magnetized alone the vertical at proposal 1 is nearly 333.72% higher than that of the proposal 3, the magnetic force of X direction increases by about 286.91%, and the magnetic force of Y direction increases by about 66. 79%. Magnetic force of Y direction magnetized alone the external field force lines at proposal 1 is nearly 55. 12% higher than that of vertical magnetization, the magnetic force of X direction increases by about 17.09%, and the resultant of magnetic force increases by about 33.24%, thus it is concluded that the optimal mode of electrifying and magnetization, and provided with a certain application value.
