PURPOSE:To provide a flat oscillation brushless motor producing an oscillation in the thrust direction which can be sensed easily by human body. CONSTITUTION:A protrusion 2 is provided on the outer periphery of a rotor frame 1 and a groove 4, represented by a function y=a.sin(2ntheta), is made in the inner periphery of a motor casing 3 opposing to the rotor frame 1. When the rotor is rotated, vibration takes place in the thrust direction as well as the radial direction and thereby oscillation can be sensed easily. |
