Abstract

The invention relates to a synchronous machine with permanent magnets, having a reduced parasitic torque, used in electric drive field. According to the invention, the said machine is provided with cuttings (7) at the base of the statoric teeth (6), towards the electrical gap between the stator (4) and the rotor (2), so as to determine the effect of the presence of a higher number of slottings (5) than that wherein the multiphase winding is introduced. At 720°/(Zx2+1) degrees from an axis (d) passing through the center of the statoric sheet, clockwise, on the statoric sheet there are performed Z slottings (5) shifted with 720°/(Zx2+1) degrees, wherein there is introduced the alternating current winding and at 360°/(Zx2+1) degrees in relation to the axis d, there are performed (Z+1) cuttings (7) with the aperture oriented towards the rotor (2), shifted with 720°(Zx2+1) degrees, clockwise, Z from 6 to 48, said rotor (2) has from 2 to 24 magnetic poles, made of permanent magnets (1). In another embodiment of the synchronous machine with permanent magnets, for the purpose of reducing the parasitic torque, said machine is no longer provided with cuttings at the base of the statoric teeth (6). At 720°/(Zx2+1) degrees from an axis (d) passing through the center of the statoric sheet without cuttings, clockwise, on the statoric sheet without cuttings, there are performed Z slottings (5) shifted with 720°/(Zx2+1) degrees, wherein there is introduced the alternative current winding, Z from 6 to 48, the rotor (2) has from 2 to 24 magnetic poles made of permanent magnets (1).
