Abstract
An oscillating motor is provided which can be reciprocally rotated within a predetermined rotation region without any conversion device for changing to a linear movement, and which can be simply connected to an existing apparatus. The oscillating motor includes a set of teeth formed on the stator which are configured to engage with a corresponding set of teeth formed on the rotor when the motor is in operation. Alternately formed concave and convex regions on the teeth increase a contact area between the rotor and stator, thus increasing torque and operating efficiency of the motor without increasing size.
