Title:
FAN MOTOR CONTROL DEVICE
Document Type and Number:
Japanese Patent JPH08159082
Kind Code:
A
Abstract:
PURPOSE: To always keep proper rotational speed corresponding to resistance of a blowing passage without arranging a blowing rate sensing means such as a blowing velocity sensor on the passage.
CONSTITUTION: A rotational speed sensing means 15 senses rotational speed of a fan motor 5. A driving current sensing means 16 senses information of driving current of the fan motor 5. A flow passage resistance determination means 17 determines resistance of a blowing passage based on values of the driving current sensing means 16 and the rotational speed sensing means 15.
