Title:
RADIAL GAP TYPE MOTOR
Document Type and Number:
WIPO Patent Application WO/2006/132034
Kind Code:
A1
Abstract:
A radial gap type motor (10), wherein a stator (12) is disposed on a rotor (11) fixedly fitted onto a drive shaft (13) through a clearance in the radial direction. Armature coils (23) excited by reverse magnetism to each other in the circumferential direction are fixedly disposed on the inner peripheral surface of the stator (12), and a field coil (18) annularly wound about its axis is fixedly disposed on the side of the rotor (11) in the axial direction. First inductors (15) comprising magnetic substances having one end faces opposed to magnetic poles generated on the inner peripheral side of the field coil (18) and the other end faces opposed to the armature coils (23) and second inductors (16) comprising magnetic substances having one end faces opposed to magnetic poles generated on the outer peripheral side of the field coil (18) and the other end faces opposed to the armature coils (23) are disposed on the rotor (11) alternately in the circumferential direction. Alternatively, the field coil and the armature coils may be arranged reverse to each other.
