In this paper, an analytic magnetic field calculation method based on scalar quantity magnet of tubular reference frame with separated variables is introduced, which is a research way to work on the tu-bular permanent magnet linear synchronous motor with axial magnet. Thanks to this method, an elaborate academic analysis to magnetie field distribution of slotless motor was conducted, whose result showed the axial and radial slot magnetic distributions, while the thrust foree of the motor was calculated analytically. Then, finite element analytic method was used to testify the calculation of the magnet and the force. The verification showed that there was almost no difference between the error results produced by both of the above methods. So the validity and practicability of the magnetic field calculation method based on scalar quantity magnet of tubular reference frame with separated variables have been verified, as well as the cor-rectness of the analytic calculation of the thrust force. The radial magnet distributing experiment result of sample motor, whose measurement values are consistent with its calculation values, has been presented. And load sensor has been used to measure the rated load thrust force of the motor, which makes sure the validity of the analysis and designing of the sample motor.
