The alternating current motor (100) includes a rotor (105) and is configured to oscillate around the longitudinal axis. The rotor (105) comprises a diametrically magnetized permanent magnet (120). Furthermore, the alternating current motor includes stationary coils (110,115) having a magnetic axis substantially perpendicular to the rotor's (105) longitudinal axis. The stationary coils (110,115) are adapted to the rotor's outer periphery and are substantially coaxial with the rotor's longitudinal axis. In addition, the alternating current motor (100) includes a stator (160) adapted to the stationary coils' (110,115) outer periphery and being substantially coaxial with the rotor's longitudinal axis. The motor (100) is configured to cause the rotor's oscillation angle to vary no more than 30% between the beginning value of a frequency range of an alternating current in the stationary coils (110,115) and the ending value of the frequency range. |
