This paper mainly focuses on the characteristics of the Doubly Salient Machine.The electromagnetic parameters of the machine are designed based on the analysis of the structure and operation principle.Then analyse the static and steady characteristics, which is for the comparison with the asynchronous machine. First, the introduction about the structure, operating principle and mathematical model of the concerned DSM is given. Based on the linear disposal of excitation flux, the three-phase three-state, three-phase six-state and advanced-angle control methods are introduced and analyzed to provide a theoretical basis for doubly salient electromagnetic motor operation control. Based on the speed asynchronous machine structure, the doubly salient machine is designed, then planar Finite Element Method (FEA) is applied to analyze the magnetic field inside the motor, And a series of static characteristics are investigated, such as field distribution, air gap magnetic density, field flux, inductance, static torque, torque ripple. On the bases of FEA results, a steady analysis method for the motor system’s running steadily is proposed. And a primary research work has been done on some steady characteristics of the system, such as phase current, field flux, inductance, voltage, output torque and mechanical properties. Finally, the efficiency characteristic of the DSEM and IM is compared, which provide theoretical basis for application promotion of the DSEM. The influences on static characteristics and steady characteristics are investigated exerted by the change of the rotor tooth-width. All these provide references for the design of motor.
