Abstract:
A motor (1) is provided with a rotary shaft (2), a rotor (3), a stator (4), and a housing (5) which accommodates the rotary shaft (2), the rotor (3), and the stator (4). The stator (4) has the following: a tubular stator core (6) disposed on the periphery of the rotor (3); a coil (7) comprising a winding wire (9) wound around the stator core (6); and a substantially annular assembly plate (10) to which the winding wire (9) and a feeder line are connected. The assembly plate (10) is disposed below the rotor (3). A first opening (5c) having an inner diameter larger than the outer diameter of the stator (4) is formed in the upper part of the housing (5). The maximum value of the outer diameter of the assembly plate (10) is equal to or less than the outer diameter of the stator core (6).
