Fan motor

A fan motor comprising:

• a motor body including a stator and a rotor that rotates in response to a magnetic field of the stator;
• a fan that rotates accompanying rotation of the rotor;
• a controller that includes a circuit board configuring a control circuit to control passing of current to the stator and a circuit element attached to the circuit board;
• a heat sink that is attached to the controller and that includes a heat dissipating section for dissipating heat from the controller;
• a case body that includes a motor holder provided at a periphery of the rotor, and a center piece supporting the stator, with the heat dissipating section disposed between the center piece and the motor holder and the center piece forming an airflow passage along which airflow passes;
• an introduction section through which airflow flowing toward the heat dissipating section is introduced;
• a discharge section through which the airflow that has been introduced through the introduction section is discharged toward the fan side;
• and
• a facing section that is disposed at a downstream side of the airflow with respect to the heat dissipating section and that extends in a direction to obstruct the airflow.
