1. A motor comprising:
a stator having a plurality of coils wound therearound and a center made hollow to vertically pass through its center;
a rotor which is disposed to be spaced apart from an inner surface of the stator, and into which a drive shaft is inserted to vertically pass through its center;
a terminal block including a frame coupled to an upper side of the stator, ribs extending radially inward from the frame, and a ring portion which is coupled to the ribs and into which an upper side of the drive shaft of the rotor is rotatably inserted; and
a terminal coupled to the terminal block and electrically connected to the coil of the stator,
wherein the stator has a plurality of protrusions protruding upward from its upper surface, the protrusions being formed to be spaced apart from each other in a circumferential direction,
the frame of the terminal block has a stepped jaw protruding radially outward, and
the frame of the terminal block is inserted into the inside of the stator, which is surrounded by the protrusions of the stator, and the stepped jaw of the terminal block is inserted between the protrusions of the stator,
wherein the protrusions of the stator each have a concave insertion groove, and the coil and a connection connector are inserted into the insertion groove to be coupled and electrically connected to each other, and
the terminal has one side extending upward from an upper surface of the terminal block and the other side extending radially outward from an outer circumferential surface of the frame of the terminal block, and the other side of the terminal is inserted into the connection connector to be coupled and electrically connected to the connection connector.
