| 摘要 |
The invention concerns an electric motor assembly without collector and a device powering said motor, wherein the motor has a plurality of pairs of poles, comprising two windings each consisting of a plurality of coils in series corresponding each to a pole of the motor, the two windings being jointly coiled such that the coils of each winding are magnetically coupled pole by pole, one of the terminals (e1) of one of the windings being electrically connected to the terminal (s2) of the other winding corresponding to the opposite end of the winding, to form a common point, a rectified voltage source; two one-way static switches (T1, T2) whereof a first terminal (7, 8) is connected to the negative terminal (9) of the voltage source, and the second terminal (10, 11) is connected to one of the terminals (s1, e2) of the two windings, a dissipation circuit (17) designed to dissipate the magnetic energy of the windings when the static switches (T1, T2) are open, is connected to the positive terminal of a capacitive filter (13) and to the second terminals (s1, e2) of the static switches (T1, T2) with diodes (D1, D2). |
