Abstract
A motor control device is capable of detecting, through use of a small-sized or simple device, a state of belt tension in a belt transmitting torque of an electric motor in a motor system. A motor control device includes a drive controller that outputs a drive command signal that drives an electric motor of a motor system, and a belt tension state value calculation unit that outputs a belt tension state value on a basis of a drive detection signal detecting an angle of rotation, an angular velocity, or an angular acceleration in the motor system. The belt tension state value indicates a state of belt tension in a belt. The motor system includes a load machine, a driven pulley mechanically connected to the load machine, the belt wound onto the driven pulley, a drive pulley that the belt is wound onto, and the electric motor mechanically connected to the drive pulley.
