Abstract

To provide a rotor section structure in which flux between an inner rotor magnet and a field coil on the outer circumference functions efficiently while keeping the magnetic balance of the inner rotor magnet and a vibration motor in which eccentric copper body arrangement position effective in obtaining a vibration force is taken into account. The rotor section comprises a plate magnet having a generally rectangular cross-section where both ends of a noneffective flux range part located perpendicularly to the pole direction of a radially anisotropic magnet are cut off equally, and the rotor balance with respect to the central axis of rotation is kept. Meanwhile, as an unbalance weight of the rotor section, a weight inertial body made of a nonmagnetic material and placed in one of the spaces of the magnet formed by cutting off equally is eccentrically provided to the rotor section as an extra eccentric weight.
