Strengths and Characteristics
— Features of fan motor —
Our fan motors range from relatively inexpensive types, which feature plastic blades attached to the rotor of a typical inner rotor motor, to all-metal AC fan motors. The latter are characterized by metal blades directly welded to the rotor of an outer rotor motor.
Heat generated from the coils inside the fan motor is less likely to be transmitted externally when plastic materials are involved. However, the all-metal type excels in thermal conductivity, allowing heat to dissipate through the blades. This results in lower bearing temperatures and an extended lifespan.

— Sensor that monitors the fan motor —
In general, fan motors are used in equipment that cannot be adequately cooled by natural convection alone. If the fan motor stops, the equipment’s performance may deteriorate, or the equipment may stop functioning entirely. In some cases, internal components may be damaged, potentially causing extensive damage to associated systems.
To detect such failures in advance, many models with metal blades are equipped with fan sensors that continuously monitor the motor’s rotation speed and trigger an alarm if a decrease in speed is detected.
