Abstract: A rotation angle detection apparatus includes a magnet that is provided to a rotating shaft of a rotating body and rotates with the rotating shaft to generate magnetic flux and a magnetic sensor that is provided at a distance from the magnet and detects a magnetic flux interlinked with the magnetic sensor. The rotation angle detection apparatus has a magnet magnetic flux detection circuit that detects a magnet magnetic flux generated from the magnet, a disturbance magnetic flux detection circuit that detects a disturbance magnetic flux, which is a magnetic flux other than the magnet magnetic flux and is interlinked with the magnetic sensor, and a correction circuit that corrects a result of detection of the magnetic sensor based on a result of detection of the magnet magnetic flux detection circuit and a result of detection of the disturbance magnetic flux detection circuit.

Abstract: A controller-integrated rotating electrical machine incudes a rotating electrical machine and a control device. The rotating electrical machine is equipped with a stator and a rotor. The control device is equipped with a control circuit for an inverter circuit and an angle position sensing device which works to measure an angular position of the rotor. The control device has first substrate on which the control circuit is mounted and a second substrate on which the angle position sensing device is mounted. The first substrate is located closer to the rotating electrical machine than the angle position sensing device is in an axial direction of the controller-integrated rotating electrical machine. This minimizes adverse effects of magnetic flux, as generated by the rotating electrical machine, on operation of the angle position sensing device, thereby enhancing a measurement accuracy of the angle positon sensing device.

Abstract: A temperature sensor in a rotating electric machine is disposed or installed on a surface of a temperature detection object. The temperature detection object, i.e., an installation portion, has a thickness. The temperature sensor has an inner case housing a detector element. The inner case is made of resin. The inner case has a thickness. A temperature detecting device has an outer case housing the temperature sensor. The outer case is made of resin. A linear expansion coefficient of the outer case is, within a certain temperature range including a threshold temperature for a protection of the rotating electric machine, is smaller than an average of linear expansion coefficients of the installation portion and the inner case.

Abstract: A correction circuit stores data for obtaining coefficients of a relational expression indicating a relationship between a disturbance magnetic flux and a rotational angle error. Then, the coefficients are obtained from the data for obtaining the coefficients, and a detection result of a magnetic sensor is corrected based on the coefficients obtained, a relational expression, and a detection result of a disturbance magnetic flux detection circuit. Since it is possible to obtain the rotational angle error with respect to the disturbance magnetic flux from the coefficient obtained and the relational expression, it is not necessary to store the data indicating the relationship between the disturbance magnetic flux and the rotational angle error for all of the disturbance magnetic flux value in disturbance magnetic flux regions that may be applied.
