<p>A fan motor device is provided with a fan motor (4); an inverter section (3), which is arranged inside a housing (20) of the fan motor (4) and outputs a voltage to the fan motor (4); and a motor controlling microcomputer (5), which is arranged inside the housing (20) of the fan motor (4) and controls the fan motor (4) by outputting a control signal to the inverter section (3). The motor controlling microcomputer (5) is controlled by a main body side microcomputer (2) from the external. Thus, in the fan motor device having the inverter section in the housing, noise is reduced, efficiency is improved and furthermore, controllability is improved.</p> |
