Abstract
Constant torque range (CTR) is an important design parameter for limited-angle torque motors (LATMs), which cannot be obtained for permanent magnet (PM) slotted LATM with the configuration of poles number equal to slots number in the preliminary design. This paper presented a calculation method based on magnetic field model for obtaining the CTR of this LATM type, which provided a technical basis for the LATM optimal design. This paper firstly simplified the slotted LATM model, and then established an analytical magnetic model of LATM with 1 pole-1 slot unit on the basis of periodic boundary condition. The air gap magnetic field waveforms of 4-pole 4-slot and 6-pole 6-slot motors calculated by the analytical model are compared with the finite element method to verify its correctness. Based on this, a CTR calculation method was proposed, and the effects of the number of poles and slots on the CTR were analyzed. Finally, the correctness of the proposed method was verified by the FEM and experiment.关键词
