Motor

A motor comprising:

• a rotor including a shaft extending along a rotation axis;
• a stator radially opposing the rotor;
• a bearing that rotatably supports the shaft;
• a motor housing that accommodates the stator and that opens axially upward;
• a bearing holder that holds the bearing and that covers an opening of the motor housing;
• a bus bar assembly electrically connected to the stator and located on the bearing holder;
• and
• a circuit board located axially above the bus bar assembly and electrically connected to the bus bar assembly;
• wherein
• the bearing holder includes a holder protrusion protruding radially outward of the motor housing;
• a bus bar cover that covers a terminal through hole axially penetrating the holder protrusion is attached to a lower surface of the holder protrusion;
• the bus bar assembly includes:
• a bus bar located around the bearing and connected to a conductive wire drawn out from the stator;
• a bus bar terminal connected to the bus bar, extending axially downward, passing through the terminal through hole, and protruding axially downward from a lower surface of the holder protrusion;
• and
• a bus bar holder that covers outer surfaces of the bus bar and the bus bar terminal and includes an insulator;
• the circuit board includes a circuit terminal extending axially downward, passing through the terminal through hole, protruding axially downward from a lower surface of the holder protrusion, and connected to the bus bar terminal;
• the bus bar cover includes:
• a tubular cover portion that covers lower end portions of the bus bar terminal and the circuit terminal and that includes an open upper surface;
• and
• a flange portion extending outward from an upper end peripheral edge portion of the cover portion and fixed to a lower surface of the holder protrusion;
• the flange portion includes an annular flange projection protruding axially upward from an upper surface;
• the holder protrusion includes an annular seal recess that is recessed axially upward from a lower surface and that surrounds the terminal through hole;
• and
• the flange projection is located inside the seal recess including a seal material.
