Motor, compressor, and method of manufacturing a motor

A method of manufacturing a motor, which comprises:

• a segmented stator having a cylindrical shape extending in an axial direction and at least one stator core segment having a tooth base part, and a rotor;
• the method comprising:
• providing at least one electrical insulation body that includes a first insulation part having a through hole penetrating through the first insulation part at least substantially in a circumferential direction, a second insulation part, and a third insulation part configured to electrically insulate a first side surface on a first side in the circumferential direction of the tooth base part, which extends radially inward from a yoke segment of the at least one stator core segment, and a second side surface on a second side in the circumferential direction of the tooth base part, from a stator winding;
• inserting a portion of the third insulation part through the through hole of the first insulation part;
• disposing the first insulation part on a first side in the axial direction of the stator core segment, disposing the second insulation part on a second side in the axial direction of the stator core segment, and disposing the third insulation part on the first and second side surfaces of the tooth base part;
• and
• winding the stator winding around the at least one electrical insulation body that is disposed on the at least one stator core segment.

A stator segment, comprising:

• a stator core segment including a yoke segment that forms a circular segment of a yoke, and a tooth base part extending radially inward from the yoke segment;
• an electrical insulation body disposed on the stator core segment;
• and
• a stator winding wound around the tooth base part of the stator core segment via or over the electrical insulation body;
• wherein:
• the electrical insulation body comprises:
• a first insulation part disposed on and electrically insulating a first axial end of the stator core segment and having a through hole penetrating through the first insulation part at least substantially in a circumferential direction of the stator segment;
• a second insulation part disposed on and electrically insulating a second axial end of the stator core segment, the second axial end being opposite to the first axial end in an axial direction of the stator segment;
• and
• a third insulation part comprising:
• a first side surface insulation body disposed on a first side surface of the tooth base part on a first side in the circumferential direction;
• a second side surface insulation body disposed on a second side surface of the tooth base part on a second side in the circumferential direction, the second side surface in the circumferential direction being opposite to the first side surface in the circumferential direction;
• and
• a connection part that connects the first side surface insulation body and the second side surface insulation body, the connection part being is disposed in the through hole of the first insulation part.
