PURPOSE: To obtain a motor for PACHINKO ball launch capable of launching a PACHINKO ball with simple constitution without receiving the influence of the fluctuation of a source voltage even when it occurs.
CONSTITUTION: This motor comprises a rotor 1 fixed at a rotary shaft 3 and a stator 2 arranged in the outer periphery of the rotor 1, and the rotor 1 is formed with a permanent magnet 5 magnetized in an axial direction and rotor cores 5, 6 formed at both terminal sides of the permanent magnet 4 at tooth pitch being shifted by 1/2, and a stator core 12 which forms the stator 2 is formed in eight polar structure, and teeth are formed at those poles so as to face with each tooth of the rotor cores 5, 6. The teeth are arranged at tooth pitch being shifted by every 1/4, and an A-phase coil connected directly to a power source and a B-phase coil connected to the power source via a capacitor for phase leading are applied to the poles. By employing such constitution, an angle of rotation at power source frequency of 1Hz is of four steps, and is of one pitch of tooth of the rotor cores 5, 6.
