Abstract: A plastic-package motor, including: a rotating shaft, a rotor assembly, a plastic-package stator, a front end cover, a rear end cover, an injection-molding end plate, and a conducting strip. The rotating shaft and the rotor assembly are installed and connected together. The plastic-package stator is sleeved outside the rotor assembly. The front end cover is injection-molded on the injection-molding end plate at the bottom of the plastic-package stator. The injection-molding end plate is covered outside the front end cover. The rear end cover is installed at the other end of the plastic-package stator, and two ends of the rotating shaft are supported on a bearing of the front end cover and a bearing of the rear end cover, respectively. One end of the conducting strip is electrically connected with the front end cover.

Abstract: An assembly structure, including an end cover and a shell. The end cover includes a rabbet, a side wall, and an end surface. The shell includes an end part. A plurality of clamping grooves is arranged at a bottom of the rabbet and on the side wall of the end cover. Through holes are arranged above the clamping grooves and on the end surface of the end cover and communicate with the clamping grooves. A plurality of notch grooves is arranged at the end part of the shell. Clamping strips are arranged above the notch grooves and at the end part of the shell. The end cover is installed at the end part of the shell. The clamping strips are embedded in the clamping grooves for allowing the shell and the end cover to be connected together.

Abstract: A strip stator including: a strip stator core; a plurality of upper end insulation groups; and a plurality of lower end insulation groups. The stator core includes two ends. Each upper end insulation group includes at least two upper end insulations connected together by injection molding. Each lower end insulation group includes at least two lower end insulations connected together by injection molding. The upper end insulation groups and the lower end insulation groups are arranged on the two ends of the strip stator core, respectively.

Abstract: A combination of a motor and a wind wheel. The motor includes a shaft (11) including a plurality of mounting holes (21). The wind wheel (2) is arranged on the motor (1). A plurality of wind blades (22) is arranged on the mounting plate (21). A first through hole (210) is disposed on a middle part of the mounting plate (21). A boss (23) is disposed on the mounting plate (21) outside the first through hole (210). A second through hole (230) is arranged on the boss (23). A plurality of mounting holes (110) is arranged on the shaft (11). The shaft (11) passes through the first through hole (210). A screw (3) passes through the second through hole (230) and is inserted into the mounting hole (110) for fastening the wind wheel (2) on the shaft (11).

Abstract: A heat-dissipation structure for a motor controller. The heat-dissipation structure includes a control box, a circuit board, a plurality of radiators, and IGBT modules. The circuit board is installed in the control box. Each radiator includes a side plate and a heat dissipation block protruding from the side plate. The side plate is attached to an inner wall surface of the control box. The IGBT modules are installed on the heat dissipation block, and the pin terminals protruding from the IGBT modules are in electric or electronic connection with the circuit board.

Abstract: A daughter circuit board of an electronically commutated motor for interface signal conversion, including circuit units integrated on the daughter circuit board and five ports for communicating with a control system of a user terminal. The five ports include: a R/T port, a Vcc port, a Common port, a Vsp port, and an FG port.

Abstract: A water drainage system for a blower, including a shell body (1) and a shell cover (2). The shell body (1) is fitted with the shell cover (2) to form a cavity (3) in which a wind wheel is arranged. A side wall of the shell body (1) is protruded to form a wind pipe (4) which is connected to the cavity (3). The wind pipe (4) is provided with a water outlet (41).
