FIELD: electricity. ^ SUBSTANCE: proposed electric machine (10) includes at least eight excitation poles (P) located in stator (11) and collector rotor (13) with pole teeth (Z) the number of which differs from the number of excitation poles; at that, on pole teeth there located is at least one section (S) of winding the ends of which are connected to commutator bars (L) which are electrically connected in pairs to each other by means of contact jumpers (K), are supplied with electric power through carbon brushes (B) and the number of which is divisible by the number of pole teeth. At that, according to this invention, the above number of commutator bars (L) in this electric machine is divisible by the half of the number of pairs (P) of excitation poles, but is not divisible by the number of pairs of poles, which is even. ^ EFFECT: reducing torque moment pulsations and noise of electric machine at simultaneous decrease of overall dimensions and reducing labour input of its manufacture. ^ 10 cl, 9 dwg |
