The motor is not completely enclosed, but it can be used to transmit air in the case of ordinary smoke or slight debris. It is not recommended for long-term or severe dusty environment.
It is a brushless motor, and the speed can be reduced by the inverter, but long-term low-speed operation is not recommended. If the speed is low for a long time, insufficient air flow will cause the shaft to overheat. It should not exceed 60Hz, because the load is too large and the temperature rise is too high to cause the machine to burn.
It is not recommended that you install speed controllers by themselves, and the burn-in caused by this is not responsible for after-sales.
