An objective of the present invention is to reduce the downtime which occurs when changing a servo motor device. A servo motor device includes a motor section and a reduction gear configured to output a driving force by reducing a speed of rotation of the motor section, wherein a control device includes a detecting section configured to acquire detected information about operation of the motor section, and a computing section configured to generate an approximate curve based on a behavior for a time sequence of a parameter and to calculate predicted lifetime information of the servo motor device based on the approximate curve thus generated, wherein the parameter has been calculated by means of the detected information.

Servo motor device, and control method

A vibration power generator includes a coil attached to a frame and a moving body that is supported on the frame through a spring and has a magnet facing the coil, and relatively moves the moving body with respect to the coil to generate electric power. The moving body has the magnet, a yoke material that is attached to the magnet and forms a magnetic circuit, and a weight member. Average specific gravity of the moving body is 8 g/cmor more.
