PROBLEM TO BE SOLVED: To provide a radial gap motor for eliminating a necessity of a sliding member such as a slip ring for supplying power to a magnetic field coil or an armature coil, simplifying a structure, and overcoming problems that a life of the motor is shortened by a contact abrasion in the slip ring and power is unstably supplied. SOLUTION: The radial gap motor 10 has an armature 12 spaced from a rotor 11 fitted and fixed to an exterior of a drive shaft 13 and radially disposed through an air gap. The armature coil 23 is fixed and disposed on an inner circumference of a stator 12, and alternately excited in the circumferential direction in reverse polarity. One magnetic field coil 18 is fixed and disposed on the side of the rotor 11 in the axial line direction, and annularly wound around an axial line. The rotor 11 comprises first and second induction elements 15, 16 circumferentially and alternately disposed. The first induction element 15 comprises a magnetic material for facing a magnetic pole generated on an inner circumference of the magnetic field coil 18 on one end face, and facing the armature coil 23 on the other end face. The second induction element 16 comprises the magnetic material for facing a magnetic pole generated on an outer circumference of the magnetic field coil 18 on one end face, and facing the armature coil 23 on the other end face. Alternatively, the magnetic field coil and the armature coil can be oppositely disposed. COPYRIGHT: (C)2007,JPO&INPIT
