Abstract: An identification method that identifies a type of a fan motor unit in an air blowing system that includes: a fan motor unit including a motor, a fan, and a casing; and a controller that controls the fan motor unit. The fan motor unit blows air to the outside. The identification method includes: a first step of the controller outputting, to the fan motor unit, a first air flow rate instruction that is output at a time of performing control to cause the fan motor unit to operate normally; a second step of the controller acquiring a first speed notification that is output from the fan motor unit in response to the outputting of the first air flow rate instruction; and a third step of the controller identifying, based on the first air flow rate instruction and the first speed notification, a type of the fan motor unit and outputting a type identification signal indicating the identified type.

Abstract: A motor unit includes a motor, a substrate, a motor case, a connector, and a restriction portion. In the motor, a rotor including a rotary shaft extending in an axial center direction rotates about an axial center of the rotary shaft as a rotation center. The substrate is provided with a circuit element constituting a drive circuit for driving the motor. The motor case houses the motor and holds the substrate. The connector includes a connection terminal directly connected to the substrate. The restriction portion restricts displacement of the connector with respect to the substrate by coming into contact with the connector.
