| 摘要 | A DC electric motor has a stack of laminations defining a rotor with at least two pairs of poles and an even number of slots at least equal to 8. The rotor also has a commutator with an even number of segments and a closed distributed rotor winding. The winding extends in the slots and is connected in a predetermined manner to the segments of the commutator. The rotor winding has a winding section of the lap type, connected to two consecutive segments of the commutator and, in series with this, a plurality of winding sections of the wave type. These winding sections all span an identical number of slots. | ||

| 主权项 | 1. A direct current electric motor with at least two pairs of poles, comprising: a rotor including a stack of laminations that defines an even number of slots at least equal to 8, a commutator with an even number of segments, and a closed distributed rotor winding, the wire of which extends in said slots and is connected in a predetermined manner to the segments of the commutator; and brush gear for transferring electrical power to the rotor winding via the commutator, wherein the rotor winding comprises a single winding section of the lap type, connected to two consecutive segments of the commutator and, in series with this, a plurality of winding sections of the wave type, said winding sections all spanning an identical number of slots. | ||
