Abstract
A wiper device including a wiper motor that includes a rotor and a coil to generate a rotating magnetic field, and that causes a wiper blade to perform a wiping operation by rotating the rotor according to the rotating magnetic field, a drive section that drives rotation of the wiper motor by performing current switch-on in the coil so as to generate the rotating magnetic field, and a controller that controls the drive section by a timing for current switch-on in the coil based on at least a rotation position of the rotor.
