Motor with bus-bar assembly

A motor, comprising:

• a stator assembly including a stator core, an upper insulator covering and insulating an upper portion of the stator core, and a lower insulator covering and insulating a lower portion of the stator core;
• and
• a bus-bar assembly including a bus-bar having a plurality of connecting terminals formed on a circular bus and a contact portion electrically connected to a coil, and a bus-bar housing accommodating the bus-bar therein,
• wherein the stator core includes a circular core base and a plurality of teeth formed radially from the circular core base,
• wherein the upper insulator includes an upper-base-insulating portion configured to cover upper and central portions of the circular core base,
• wherein the upper-base-insulating portion includes a plurality of coil guides, wherein a coil passage is formed between the plurality of coil guides,
• wherein the bus-bar housing is coupled to a bus-bar seat defined in a central portion of the upper insulator,
• wherein the coil wound around a first tooth is wound around a second adjacent tooth of the plurality of teeth while directly contacting with the contact portion by passing through the coil passage.
