Abstract

PURPOSE:To stop an air mix door promptly when it has reached the specified position by shortcircuiting the two end terminals of the motor by the use of counter- electromotive force to be generated in the motor. CONSTITUTION:Output of an air mix door position sensor 12 is compared by a comparator 6 with the output of an air mix door position setting device 11. The outputs of comparators 7, 8 are used as a signal to rotate the air mix door in the direction toward cooler or warmer side than the current position. When the air mix door has reached the intended position, the comparators 7, 8 cease to emit output and the motor 9 is shut off with the driving current. The two end terminals of this motor 9 is, at this time, shortcircuited with a transistor 17 or 18 interposed, by the action of the counter-electromotive force of the motor 9, and the air mix door stops at the intended position.
