摘要： A fan motor includes: a single-phase stepping motor including a stator excited by applying an electric current to a coil to function as a single-phase magnetic pole, and a rotor which has a permanent magnet magnetized to a single phase and rotates as the magnetic pole of the stator changes; an impeller which is rotated by a rotating shaft of the rotor; and a drive circuit for controlling an application of a current to the coil. The drive circuit applies pulse voltage to the coil and the coil constant is set so that a mean value of the current applied to the coil is 10 mA or smaller.

摘要： It is a stepping motor enabled to prevent generation of detent torque therein and arbitrarily set the detent torque. This stepping motor has a rotor constructed by rotatably supporting a shaft, to which a multi-polarized permanent magnet (3) is fixed, and a stator consisting of a plurality of air-core coils (4, 5), each of which is made from a predetermined number of turns of a wire wound around an axis perpendicular to a central axis of rotation of the rotor, to be placed along a peripheral surface of the permanent magnet (3) and to be evenly disposed to face one another.
