Abstract (en)
[origin: US2006153677A1] A mini-fan has a drive motor having an external rotor ( 222 ) and an internal stator ( 244 ). The external rotor ( 222 ) is equipped with a rotor shaft ( 234 ) that has a necked down portion ( 258 ) in the region of its free end ( 235 ). The mini-fan ( 216 ) has a bearing tube ( 238 ) on whose outer side the internal stator ( 244 ) is mounted and in whose interior is arranged a bearing arrangement ( 236 ) in which the rotor shaft ( 234 ) is rotatably supported. A closure arrangement ( 262 ) serves to close off the bearing tube ( 238 ) in liquid-tight fashion at one end, and is equipped, in the region of the necked down portion ( 258 ) of the rotor shaft ( 234 ), with at least one resilient securing member ( 260 ) that engages into that necked down portion ( 258 ) and secures the rotor shaft ( 234 ) against being pulled out of the bearing arrangement ( 236 ).
