Abstract

The winding front end from the winding machine is wound around a commutator lead for a specified number of turns, and then wound around the corresponding salient pole. Then, continue to wind around other commutator leads and other salient poles in the same way. After winding around the same commutator lead that was wound for the first time around the winding front end, cut off the winding. Only the winding portion that is to be wound around the commutator lead in synchronization with the winding wire delivered from the winding machine needs to have its insulation removed and the wound portion of the commutator lead to be welded before winding.

Description

technical field

[0001] The invention relates to a rotor of a small electric motor and a manufacturing method thereof. Such a rotor provides a satisfactory electrical connection between the winding ends and the commutator leads in an easily manipulable manner. Background technique

[0002] The connection of commutator segments and winding ends according to the prior art is described with reference to FIG. 7 . Fig. 7 is a schematic perspective view of a commutator unit of a small motor. In the figure, numeral 11 represents the shaft of the rotor, 22 is a commutator segment; 24 is a commutator core; 26 is a commutator lead wire. Therefore, the commutator unit includes a commutator segment 22 and a commutator lead wire 26 provided on a commutator core 24 made of resin, and commutator lead wires 26 for connecting winding ends to each commutator lead wire at the commutator segment The ends of 22 are integrally formed therewith. Fig. 8 shows the shape of the commutator unit sho...
