摘要： An armature manufacturing method includes an insulating member disposing step for disposing an insulating member on a core so that first portions of the insulating member protrude to one side in an axial direction from end faces of tooth portions on the one side in the axial direction. The armature manufacturing method includes a bending step for bending, toward each of the tooth portions, the first portions of the insulating member that protrude from the end face of each of the tooth portions on the one side. The armature manufacturing method includes a winding looping step for looping a winding around each of the plurality of tooth portions on which the bent first portions are disposed.

摘要： A method (300) of electrically insulating a conductive component (156, 256) for an electric machine (52, 110). The method (300) includes applying (306) a first dielectric, by dispersion coating, to the conductive component (156, 256) to define a first dielectric coating (160, 260). The method (300) also includes applying (310) a second dielectric, by electrostatic coating, to define a second dielectric coating (162, 262). The first dielectric coating (160, 260) and the second dielectric coating (162, 262) can then be cured (312).

摘要： Provided are a stator capable of substantially preventing a decrease in torque and a rotary electric machine including the stator. A stator (2) includes a stator core (20), an insulator (4), and a coil (5). The stator core (20) includes: a yoke (21) having an annular shape; and teeth (22) protruding from the yoke (21) to the inside of the yoke (21). The insulator (4) covers at least a part of the stator core (20). The insulator (4) includes: a first face (41) facing the coil (5) wound around the teeth (22); and a second face (42) facing the yoke (21). The first face (41) is perpendicular to the protrusion direction of the teeth (22). The second face (42) includes: a first perpendicular face (421) perpendicular to the protrusion direction of the teeth (22); and a first inclined face (422) inclined toward the first face (41) with respect to the first perpendicular face (421). The yoke (21) includes an inner circumferential face (211) facing the second face (42).

摘要： A stator bar mold insert (200) includes an upper portion (210) and a lower portion (220). A central cavity (230) is disposed between, and defined by, the upper portion and the lower portion. The central cavity is configured for use with a stator bar (10). A low friction material (240-244) lines the central cavity, and the low friction material substantially surrounds the stator bar located inside the stator bar mold insert.

摘要： A power tool motor is provided including a stator assembly and a rotor assembly rotatably disposed within the stator assembly. The stator assembly includes: a generally-cylindrical lamination stack having a stator ring and stator teeth extending radially inwardly towards a center bore arranged to receive the rotor assembly therein; an end insulator disposed at an and of the lamination stack and having an outer ring and teeth portions extending radially inwardly from the outer ring towards a center of the end insulator; and stator windings wound around the stator teeth and the teeth portion of the end insulator. A generally cylindrical seal member is disposed to interface with an end of the stator, which includes a mating surface having indents configured to mate with ends of the stator windings or ends of the teeth portion of the end insulator to substantially seal respective gaps therebetween from entry of workpiece particulate.
