    Abstract: A position detecting device has an output circuit, which controls voltages of signal lines connecting a power supply and a ground by a power side transistor and a ground side transistor. An output signal line connects a connection point of the signal lines and an output terminal. A first comparator circuit outputs a signal “1” when a current flowing in the line between the power supply and the connection point is larger than a normal current flowing into the ground from the power supply in a normal state. A second comparator circuit outputs a signal “1” when a current flowing in the line between the connection point and the ground is larger than the normal current. When the signal “1” is output from the first comparator circuit or the second comparator circuit, a cutoff circuit turns off a switch disposed in the output signal line.

    Abstract: A cover device includes a terminal receiving portion and a terminal member while the terminal member is received in the terminal receiving portion. In the terminal member, a third wall connects between one end portion of a first wall, which is directed in an inserting direction of a motor terminal into the terminal receiving portion, and one end portion of a second wall, which is directed in the inserting direction. A length of the third wall, which is measured in a direction directed from a first connection between the first wall and the third wall to a second connection between the second wall and the third wall, is longer than a distance between the first connection and a second inner peripheral surface of the terminal receiving portion and is longer than a length between the second connection and a first inner peripheral surface of the terminal receiving portion.

    Abstract: A position detector includes a Hall element that detects a magnetic flux density and a temperature detection element that detects the temperature of the Hall element. In a rotation angle calculation process, a temperature correction value a is calculated by substituting a detection temperature t of the temperature detection element and a reference maximum voltage V0 at a reference temperature t0 for a=V0×k (t−t0). Next, a correction maximum voltage Vt is calculated by substituting the temperature correction value a for a temperature characteristic formula of Vt=V0+a. Further, a rotation angle θ of a magnet relative to the Hall element is calculated by substituting an output voltage VH of the Hall element and the correction maximum voltage Vt for θ=sin−1 (VH/Vt). Since the correction maximum voltage Vt is corrected according to the temperature, the rotation angle is accurately detected.
