Abstract
The utility model discloses a separate salient pole of a sector salient pole rotor of a motor, and helps to solve the technical problems that wiring is difficult and a whole conventional motor is poor in ventilation and heat radiation because a reserved lead wire space inside the motor is narrow. The separate salient pole comprises a mandrel (5), and threaded through holes (6) are arranged on the mandrel (5) at intervals and are equidistant to each other. Each of a first group of salient pole rotor punching sheets (1) is provided with a first mandrel through hole (2), and each of a second group of salient pole rotor punching sheets (3) is provided with a second mandrel through hole (4) having a gap. The first group of salient pole rotor punching sheets (1) and the second group of salient pole rotor punching sheets (3) are alternately connected with and penetrate the mandrel (5), and gaps arranged on the second group of salient pole rotor punching sheets (3) are arranged to correspond to the threaded through holes (6) that are arranged on the mandrel (5) at intervals and are equidistant to each other. One end of each of double-thread screws (10) is in screw joint with each threaded through hole (6) arranged on the mandrel (5). The separate salient pole of the sector salient pole rotor of the motor is quite convenient to mount and machine.

The 6th goes on foot, along the first mandrel through hole in first group of field spider punching the other end of first group of field spider punching from mandrel is laminated on the mandrel, then, along the second mandrel through hole in second group of field spider punching second group of field spider punching is laminated on the mandrel, alternately first group of field spider punching of cross-under and second group of field spider punching worn mandrel full;
The 7th step, the other end of another L shaped plate and mandrel is welded together, finish the assembling of single magnetic pole;
One end of the 8th step, double threaded screw passes that the tapped through hole on mandrel is screwed onto behind the breach that arranges in second group of field spider punching;
The 9th the step, the winding solderless wrapped connection is formed field spider at single magnetic pole;
The tenth step, get out screw in the rim upper edge of machine shaft with the axial vertical direction of rotating shaft;
The 11 the step, by the other end of double threaded screw, single magnetic pole is connected on the rim of machine shaft.
The present invention is connected changing bolt into the connected mode of dovetail slot between fan-shaped field spider iron core and the complete machine rotating shaft, when guaranteeing that electric and Mechanical Reliability is high, machine adds that difficulty reduces, operating procedure simply, convenient especially the installation and processing.
