Motor

A motor comprising:

• a rotor rotatable about a center axis;
• and
• a stator that drives the rotor;
• wherein
• the rotor includes:
• a magnet radially opposed to the stator;
• a cylindrical yoke to which the magnet is fixed;
• and
• a rotor hub that holds the yoke;
• the rotor hub includes:
• a cylindrical rotor base;
• a flange on which an annular plate is able to be placed on a surface oriented toward one side in an axial direction;
• and
• a protrusion protruding from an end on the other side in the axial direction of the flange toward the other side in the axial direction;
• the flange is located radially outward with respect to the rotor base, extends in a circumferential direction, and is located on one side in the axial direction with respect to the stator;
• the protrusion includes:
• a leading end to which the yoke is fixed;
• and
• a connector that connects the end on the other side in the axial direction of the flange and the leading end;
• a minimum width of the connector in a direction intersecting a direction in which the protrusion protrudes is smaller than a maximum width of the leading end in the radial direction;
• and
• a radial position at an end in a radially inward direction of the leading end is located radially outward with respect to a side surface in the radially inward direction of the magnet.
