摘要： PROBLEM TO BE SOLVED: To shorten the length of a coil end part by a large extent. SOLUTION: A straight flat wire is formed into a U shape in advance, the two sides of a straight line are inserted into slots that are adjacent, while sandwiching stator gear teeth, and both edges of the inverted U-shaped side of a coil are connected with a thin plate rod-shaped piece, thus forming the coil to achieve a one-turn closed circuit. By making an inverted U-shaped side end face for obtaining a stator coil for forming a prescribed number of turns, the thin plate rod-shaped pieces overlap for connecting by inserting the plurality of coils, and by connecting both edges of the inverted U-shaped side, the plate thickness at a part where the both are overlapped is reduced by half, so that the thickness corresponding to the plate thickness of a flat-square wire coil is achieved, when both of them are overlapped.

摘要： PURPOSE:To make improvements in the stability and responsiveness of opening control, by compensating the revolving speed of a motor according to the controlling state of an air-mix door, in case of a device which controls a degree of opening of the said door according to operating conditions of an air conditioner by the motor for driving. CONSTITUTION:The desired temperature of blowoff air out of an upper blowoff port Du is calculated from an output signal Ts out of a temperature setter Rs and another output signal out TR of a car room upper temperature sensor SRU at an operational device E1, and on the basis of a deviation between this desired temperature and an actual temperature TD out of a sensor SDU, a control angle thetao for an air-mix door C is calculated, outputting it as a voltage signal Vo. And, a deviation between this voltage signal Vo and the output voltage of a potentiometer Rp detecting the actual opening of the air-mix door C is found by a feedback device E2, outputting it as a motor control signal Mc. This control signal Mc compensates its selection according to output SVC of an opening range judging device E4, controlling an opening control motor D with the control signal after compensation.
