Abstract

The present invention provides a fan device and a method of manufacturing the fan device, which prevent a connection part of a housing from being an obstacle when adjusting the balance of a rotor part. The fan device of the present invention is a fan device (1) comprising a stator part (10), a rotor part (20) having an impeller (22), and a casing (30) for accommodating the stator part (10) and the rotor part (20), the casing (30) includes a side wall portion (31) surrounding the periphery of the impeller (22), a base portion (32) supporting the stator portion (10) and a rotor portion (20), and connecting the side wall portion (31) and the base portion (32) The connection part (33) connected between, the casing (30) is made of at least the first member (30a) and the second member (30b) combined with the first member (30a) these two members, the first The member (30a) includes at least one connection portion (33) and at least a part of the base portion (32), and the second member (30b) includes at least one connection portion (33).

Description

technical field [0001] The present invention relates to a fan device and a method for manufacturing the fan device. Background technique [0002] In a general blower (fan unit), due to product errors, processing errors, assembly errors, etc. Dynamic imbalance. [0003] Therefore, in the fan device, in order to eliminate the dynamic unbalance of the rotor unit, it is necessary to add counterweights (balance adjustment counterweights, balance weights) to the rotor unit (refer to Patent Document 1). [0004] For example, balance adjustment is performed by adding counterweights (balance adjustment counterweights) before assembling the rotor unit to the fan unit after manufacturing the rotor unit to eliminate dynamic unbalance of the rotor unit (see Patent Documents 2 and 3). [0005] prior art literature [0006] patent documents [0007] Patent Document 1: Japanese Patent Laid-Open No. 2013-061063 [0008] Patent Document 2: Japanese Patent Laid-Open No. 2010-025087 [00...
