摘要： In order to make a torque sensor unnecessary, a magnetic modulation gear device 30 is configured to include an input shaft 23, an output shaft 32b whose speed is changed with respect to the input shaft 23 through a speed reduction unit and which outputs torque, an input shaft-side sensor 35 that measures a rotation angle of the input shaft 23, and an output shaft-side sensor 36 that measures a rotation angle of the output shaft 32b. For example, a drive device 1 includes the magnetic modulation gear device 30, a drive source 20 that inputs torque to the input shaft, and a control device 40 that controls an amount of operation of the drive source on the basis of the measured rotation angle of the input shaft and the measured rotation angle of the output shaft such that a target torque is obtained and controls the torque of the output shaft without using a torque sensor.

摘要： The objective of the present disclosure is to obtain an electric rotating machine apparatus (100) and an electric power steering apparatus (150) in which in order to drive an electric rotating machine (2) having windings of two systems, a sensor (17) and control circuits (16) of the two systems are provided and in which while the independence of each of the systems and the heat-radiation performance of control circuit boards (4) are secured, communication between the control circuits (16) of the two systems and connection thereof with the sensor (17) are realized with a small size and at a low price. A first terminal group (37a) and a second terminal group (37b) connect
a first control circuit board (4a) on which a first control circuit (16a) for controlling a current in the winding of a first system is mounted,
a second control circuit board (4b) that faces the first control circuit board (4a) with respect to the axis line of an output axle (21) and on which a second control circuit (16b) for controlling a current in the winding of a second system is mounted, and
a sensor circuit board (40) that faces the axle end of the output axle (21) and on which the sensor (17) and a communication line (14) are mounted.
