Abstract
A winding tool (10) is used for connecting pairs of motor stator winding leads (91b-98b, 91c-98 c) and cutting of the connected pairs of leads to a predetermined length. The winding tool (10) includes a first part (100) received in the rotor space (88) in the motor stator (12) and a second part (102) projecting from a first end portion (72) of the motor stator. The first part (100) of the winding tool (10) has a cylindrical outer surface (116) engageable in an interference fit with a cylindrical inner surface (86) of the motor stator core (80) to resist radial and axial movement of the winding tool relative to the motor stator (12). The winding tool (10) has a plurality of slots (131-138) spaced circumferentially about an axis (30) and extending along an outer surface (126) of the second part (102) of the winding tool (10). The number of slots (131-138) is equal to the number of magnetic poles of the motor stator (12). The slots (131-138) have an axial length approximately equal to the predetermined length of the connected pairs of leads (91b-98b, 91c-98c).
