Ceiling fan motor and ceiling fan

A ceiling fan motor, comprising:

• a shaft centered at a center axis extending in an up-down direction;
• a stator fixed to the shaft;
• an upper motor cover having a tubular portion which surrounds the stator in a circumferential direction;
• a bearing unit including at least one bearing member which rotatably supports the upper motor cover with respect to the shaft;
• a lower motor cover attached to a lower portion of the upper motor cover;
• a rotor magnet fixed to an inner surface of the tubular portion;
• and
• a circuit board arranged below the stator,
• wherein the stator includes a stator core, an insulator arranged to cover at least a portion of a lower surface of the stator core and a coil wound around the stator core with the insulator interposed therebetween,
• the upper motor cover is a ferromagnetic body,
• the circuit board includes a board body having a board surface which intersects the up-down direction, a rotation sensor attached to the board body and opposed to the rotor magnet in the up-down direction and a circuit component larger in mass than the rotation sensor,
• if there is defined an imaginary line which is orthogonal, when seen in the up-down direction, to a line interconnecting the rotation sensor and the center axis and which passes through the shaft, a gravity center of the circuit board is positioned in one of two areas of the circuit board divided by the imaginary line, where the rotation sensor exists,
• the circuit board is fixed to the insulator, and
• a position where the circuit board is fixed to the insulator includes a position located radially outward of a midpoint between an outer edge of the circuit board and the center axis in a radial direction.
