“…Typically, one of the three methods can be employed to calculate a stepping motor's behavior: analytical method, combined analytical-numerical method and numerical methods (mainly the FEM) [1] . The first one can achieve a solution rapidly with an accuracy limitation when saturation effects and/or complex geometries have to be taken into account.…”

“…The Tooth Layer Specific Permeability (TLSP) method is an extremely typical combined analytical-numerical approach [1], [5], [6] , which mainly consists of four steps: Calculation of tooth layer magnetic parameters (such as tooth layer magnetic voltage drop, magnetic flux and tooth layer magnetic coenergy), establishment of a database for tooth layer magnetic parameters, construction and solution of the motor's nonlinear equivalent magnetic network, acquirement of electromagnetic torque as well as other behaviors of a stepping motor. In TLSP method, tooth layer shown in Fig.1, which is composed of the stator fine tooth, the air gap and the rotor fine tooth should be analyzed by FEM to acquire its magnetic parameters first of all, then, a database of magnetic parameters under different sizes of a tooth layer should be established [5] , which can be called in solution of the nonlinear equivalent magnetic network.…”

Compared with the Tooth Layer Specific Permeability (TLSP) method being mainly adopted so far to calculate the electromagnetic torque of stepping motors, a new method is proposed in this paper, which is called the Tooth Layer Calculated Torque (TLCT) method. The concept of TLCT is defined firstly and its correctness when used to calculate the electromagnetic torque is proved theoretically at the same time. Then how to use the TLCT method in calculating the electromagnetic torque in stepping motors is described. At last, a comparative research among the TLSP method, the TLCT one and the finite element one (FEM) is performed, with the fact that, the TLCT method features simplified calculation and high accuracy compared with the former method.

Stepping motors are highly preferred in spacecraft applications because of their simple structure, convenient control and lack of accumulated error. In satellite antenna drive systems, reliability and fault tolerance have been paid more and more attention. Accordingly, to enhance the reliability of the electrical system in the field of aerospace, the redundancy technology, which can effectively improve the system reliability while reducing the requirements of components, was applied in the design of hybrid stepping motors (HSM), a dual-redundancy two-phase HSM which has two sets of stator windings was designed in this paper. The mathematical model of stepping motor and the specific structure parameters of the motor are given. The torque-frequency characteristic was regarded as the key to measure the performance of the motor proposed in this paper. The results of 3-D finite element modeling are presented. The corresponding performance experiment on the designed motor was carried out and both the simulation results and the experimental results verified the validity and superiority of the dual redundancy HSM.

“…The idea is to merge the two domains and to develop a global optimization approach for design and control by applying optimal control theory [12][13][14][15][16] and nonlinear optimization algorithms on magnetodynamic models of an electric machine. This work is applied on a hybrid stepper motor [17][18][19][20][21][22], to prove the feasibility of the approach on a realistic case.…”

This paper presents a global optimization approach aiming to improve the energy efficiency of electrical machines. The process is made on a hybrid stepper motor allowing to simultaneously optimize design and command. This approach is axed around Pontryagin's maximum principle, which is applied to a magnetodynamic model based on permeances network model. The originality of the proposed approach is to obtain in the same process, the minimization of the energy by optimal control and the minimization of the energy by optimal sizing.
