Abstract: A motor control device is provided with: an electric motor which drives an applying mechanism for applying torque to the wheels of a vehicle, and has three coils; a drive circuit that supplies current individually to the three coils; and a controller that controls the drive circuit on the basis of the operation amount of an operating member of the vehicle, and adjusts the output of the electric motor. When the vehicle is stopped, the controller executes swing control to periodically increase or decrease the rotary motion of the electric motor, even if the constant state of the operation amount is continued after the operation amount is constant, and the power generated by the applying mechanism and the power received by the applying mechanism are equalized and the rotary motion of the electric motor has stopped.

Abstract: A film capacitor includes a body including a core body formed of an insulating material and metalized films which are wound around the core body; and first and second terminal electrodes disposed on both end surfaces in an axial direction of the body, respectively, a cross section perpendicular to an axial direction, i.e., z direction, of the core body having an oval outer periphery having a major axis and a minor axis, and an inner periphery defining a slit extending along the major axis. The provision of the core body makes it possible to suppress loosening of the metalized films or occurrence of a gap between the metalized films, thus making the film capacitor having a high insulation property.
