[0027] The specific usage and function of this embodiment are as follows: In this embodiment, during use, the operator first pulls one of the arc-shaped connecting brackets 205, then secures the ducted fan 100 with four mounting screws.

When both the timing switches a406 and b408 are pressed, the rate at which the numbers on the display screen of the control panel 203 increase doubles. When the timing value on the control panel 203 reaches the set range, the alarm on the control panel 203 activates, automatically prompting staff to maintain the ducted fan 100 and reducing the occurrence of sudden malfunctions and downtime.

[0028] Finally, using the overall technical solution of this application, the principle and function of preventing aging of the stator windings of the ducted fan internal rotor motor are explained as follows: This application achieves stator winding anti-aging through the synergistic effect of three major technical systems: detection and control, automatic heat dissipation, and status-related early warning. Specifically: A detection and control system that monitors winding temperature and mechanical installation stability in real time avoids overheating and aging caused by temperature blind spots and prevents vibration from aggravating insulation wear. Specifically, temperature sensor 204 directly contacts the winding and transmits temperature data to control panel 203 to capture the winding temperature rise status in real time. U-shaped limit frame 206 is fixed by arc-shaped connecting bracket 205, forming a physical block for the mounting screws and preventing increased vibration or changes in heat dissipation gaps caused by loose screws during equipment operation. L-shaped anti-touch bracket 201 covers the control panel buttons, and combined with the elastic limit of helical spring a, it not only avoids misoperation but also facilitates quick unlocking during maintenance.

[0029] Furthermore, by combining an automatic heat dissipation system that triggers active airflow circulation based on temperature, when the temperature sensor detects that the winding temperature is higher than the set threshold, the control panel 203 instructs the electric telescopic rod 307 to extend, pushing the movable air guide box 304 to slide along the rectangular guide frame 303. Outside air can enter the three movable air guide boxes 304, be transported to the arc-shaped heat sink 301 through the heat dissipation hose 305, and finally blown directionally to the winding area through the circular exhaust pipe 302, forming forced convection heat dissipation, thereby actively reducing the winding temperature to a safe range and inhibiting the degradation of insulation materials caused by high temperature, such as avoiding oxidation of the enameled wire and embrittlement of the insulation layer. When the temperature is lower than the threshold, the electric telescopic rod retracts, the movable air guide box returns to the storage groove, and the closed-loop control of active heat dissipation stops.

[0030] Furthermore, by establishing a status-based early warning system for maintenance prompts based on actual workload, cumulative aging caused by untimely maintenance of the rotor motor in the ducted fan operating under high load for extended periods can be prevented. Specifically, when the ducted fan is running, airflow pushes the movable detection frame 402 to slide, and the rectangular strip 404 presses the timing switch a406, initiating the timing trigger logic of the basic timing. When active cooling is initiated, the movable air guide box triggers the timing switch b408, doubling the timing speed to reflect the high load status. When the timing value reaches the set range, the control panel alarm is activated, prompting staff to perform maintenance.

[0031] This application achieves anti-aging logic closed-loop control of the entire process from temperature monitoring → active heat dissipation → load warning → maintenance intervention, from two dimensions: "suppressing high temperature at the source" and "avoiding damage in the process" for the ducted fan internal rotor motor: by controlling the winding temperature within the Class B insulation limit (usually ≤130℃) through real-time heat dissipation, the source suppression of the insulation aging rate is directly delayed. Status-related early warnings ensure that equipment receives timely maintenance after high loads, such as cleaning heat dissipation channels and tightening components, to avoid sudden aging failures caused by the accumulation of hidden damage.

[0032] This application presents an integrated technical solution that combines three major technical systems: detection and control, automatic heat dissipation, and status-related early warning. This solution not only solves the problem of "passive lag" in traditional heat dissipation, but also fills the gap of "maintenance timing not matching working state" through an early warning mechanism, ultimately achieving long-term stable operation of the stator winding.
