Small-power motors with three teeth of rotor are usually used in drives which are battery supplied. The methods used in analysis of classical electric machines can not be applied in small-power motors calculations owing to specific construction of their rotors. It is also difficult to use the field methods because the geometry of motor cross-section is considerably complicated. Therefore to fast analysis of small-power motors working, especially in stage of designing, relatively simple model of motor can be helpful. This model should make possible the working simulation of small-power motor for different given structural and permanent magnet material parameters. In proposed model it was assumed that the magnetic circuit of small-power motors consists of concentrated elements and it is shown in the form of equivalent reluctance network. On the basis of this network the equations which describe the changes of magnetic values were formulated. The relationship between flux density and field intensity of permanent magnet was approximated with straight line of magnet working. The electromagnetic torque was calculated on the basis of principle of virtual work. The calculation algorithm for static and dynamic states was presented. The exemplary results of computations are shown in end part of the paper.
