Oriental Motor Asia Pacific Pte. Ltd. > Q＆A > Cooling Fan Qn 1: Are fans the same as motors which equipped with overheat protection devices?
Cooling Fan: Are fans the same as motors which equipped with overheat protection devices?
Answer : All AC fans in the Orix line that meet UL, CSA and EN/IEC standards either have motors with impedance protection or are equipped with a thermal protector. The DC fans include a current detection function in the drive circuit. In the case of abnormalities, the fan input current is controlled to prevent an increase in temperature and thus guard against burning out the fan motor.
