Abstract

PURPOSE: To prevent the generation of accidental trouble by means of using magnetic poles of a permanent magnet for a driving motor so as that coercive force due to the permanent magnet may act between the stator and the rotor of the driving motor when the coil is in a stopped state of no-excitation.
CONSTITUTION: If a coil of a magnetic pole B of a stator 6 may be excited, magnetic lines 11 passing through the magnetic pole B, the stator 6, and a rotor 9, are generated, and a magnetic pole 10 of the rotor 9 is absorbed by the magnetic lines 11, thereby the magnetic pole 10 of the rotor 9 and the magnetic pole B of the stator 6 are stoppted at the facing position by means of rotating the rotor 9 to the anti- clock direction by allowing the magnetic pole 10 of the rotor 9 to be absrobed by magnetic lines 11 thereof. In the coil of the magnetic pole B may be non-excited, and a coil of magnetic pole C may be excited, because that the magnetic lines 11 due to the permanent magnet are present from the pole C of the stator, the position is kept by means of allowing the magnetic pole 10 of the rotor 9 to be restrained by the magnetic pole C.
