A series-connected fan unit includes a first fan frame, a second fan frame, a first motor, a second motor and two impellers. The first fan frame has a first base and a first positioning member coupled with the first base. The second fan frame is connected to the first fan frame in series and has a second base and a second positioning member coupled with the second base. The first motor is disposed in the first base and has a first circuit board coupled with the first positioning member. The second motor is disposed in the second base and has a second circuit board coupled with the second positioning member. The two impellers are respectively coupled with the first motor and the second motor, and an insulation area is formed between the first circuit board and the second circuit board.

Series-connected fan unit

A series-connected motor unit includes a first motor, a second motor and a separation member. The first motor has a first circuit board, and the second motor has a second circuit board. The separation member has a first face and a second face opposite to the first face. The first face abuts against the first circuit board, and the second face abuts against the second circuit board.

Series-connected motor unit and a fan utilizing the same

A motor includes a base, a stator, a rotor, a circuit board and a heat-conducting insulator. The base includes a cooling plate. The stator is coupled to the base. The rotor is rotatably coupled to the base and aligned with the stator. The circuit board is received in the base and electrically connected to the stator. The heat-conducting insulator is disposed between the cooling plate and the circuit board, and abuts with the cooling plate and one face of the circuit board.

Motor and cooling fan with a circuit board having a heat-conducting insulator

An inner-rotor-type motor includes a housing, a stator, a rotor and a bearing seat. The stator is received in an assembly space of the housing. The rotor is rotatably positioned in the housing via a bearing and extends through a through-hole of the stator. The bearing seat includes a socket having a first recess and a second recess and couples to the assembly opening of the assembly space. A stopper is at least a part of the upper wall of the socket and arranged between the first recess and the second recess. The bearing can pass through an end of the socket and be positioned in the first recess, while a circuit board can pass through another end of the socket and be positioned in the second recess. Accordingly, the assembly is simplified, and the assembly convenience is improved.
