The present invention discloses an IP23 industrial ceiling fan motor with a cooling air path structure. The IP23 industrial ceiling fan motor comprises a shell, the shell comprises an upper end cover,a rotor shell and a lower end cover, a stator shaft, a hub, a stator iron core and a rotor are sequentially arranged in the rotor shell from the center to the edge, a plurality of air inlet holes areformed in the upper end cover in a surrounding mode, and a plurality of air outlet holes are formed in the lower end cover in a surrounding mode. A plurality of ventilation holes are formed in the hub, and a cooling air path main path is formed among the air inlet holes, the ventilation holes and the air outlet holes. The motor also comprises a cooling air path bypass, the cooling air path bypassand the cooling air path main path are connected in parallel and communicated with each other, the cooling air path bypass comprises a bypass air inlet and a bypass air outlet which are communicatedwith each other, and the bypass air inlet and the bypass air outlet are communicated with each other through a groove path of the stator iron core. The cooling air path main path and the cooling air path bypass are arranged in the motor in parallel, and a double-air-path structure is adopted, so that the cooling and heat dissipation effects of the motor can be greatly improved.
Description
technical field [0001] The invention relates to the technical field of motor cooling air passage design, in particular to an IP23 industrial ceiling fan motor with a built-in cooling air passage structure. Background technique [0002] In the motor design of industrial ceiling fans, the traditional design usually adopts the transmission mode of "motor + reducer", such as figure 1 As shown, a traditional motor 100, this traditional motor 100 is an inner rotor motor, including a motor rotor 160, a motor stator 150, and a motor casing 140, the motor rotor 160 is arranged inside the motor stator 150, and the motor rotor 160 is provided with a motor rotor The shaft 170 and the output end of the motor rotor shaft 170 are connected to the reducer 200 , and then connected to the fan blade through the reducer shaft 210 of the reducer 200 . Due to the high-speed operation of the motor, the upper end of the motor rotor shaft 170 is cooled by a cooling fan 120 (self-fan cooling), cover...
