According to a nozzle winding method of causing a nozzle (41) to pass between adjacent magnetic poles (12) and rotating the nozzle (41) around the magnetic pole (12), winding is carried out until the rotating nozzle (41) interferes with wound coils (201 to 242), so that a high space factor is obtained. Thereafter, according to a cam winding method, winding is carried out in a space remaining in a slot while rotating the nozzle (41) in an area not interfering with the coils (201 to 242) in the slot, thereby achieving winding with a high space factor of coils in the entire space of the slot.

A stator (1) is configured so that a plurality of power supply terminals (4) each having a tab (4a) of a planar protrusion are located on an end face of a stator core (2), the power supply side end of the winding (3) is connected to the power supply terminal (4), and a lead wire (7) with a flag type terminal (14) is connected to the power supply terminal (4), the lead wire being connected to the flag type terminal (14) in a direction intersecting a press-fitting direction into the tab (4a), the plurality of power supply terminals (4) are arranged at the same height from the end face of the stator core (2) and are inclined so that the faces of the tabs (4a) of the plurality of power supply terminals (4) are not arranged on the same plane. The flag type terminal (14) and the lead wire (7) are prevented from interfering with each other in the vicinity of the power supply terminal (4), and the lead wire (7) is arranged not higher than the flag type terminal (14) from the stator core (2), whereby the overall height of the stator is reduced.

摘要:
A low-vibration/noise brushless motor capable of limiting the height of coil ends, and a low-current-leak hermetic compressor includes the brushless motor. This brushless motor is of a three-phase full-pitch-winding type including a stator having coils (20) inserted in slots in a one coil per one slot manner. Coil ends (21) of the coils (20) are arranged such that the first coil (201) is arranged outside the second and third coils (202, 203) in a place (A) where the second and third coils (202, 203) are inserted in a pair of slots adjacent to each other, the second coil (202) is arranged from inside of the first coil (201) to outside of the third coil (203) in a place (B) where the first and third coils are inserted in another pair of slots adjacent, and the third coil (203) is arranged inside the first and second coils (201, 202) in a place (C) where the first and second coils (201, 202) are inserted in still another pair of adjacent slots. The coil ends (21) are shaped in the axial direction.
