Permanent magnet electric motor

An inner rotor permanent magnet electric motor, comprising:

• a columnar rotor including a permanent magnet portion annularly disposed;
• a shaft fixed to the rotor along a rotation axis of the rotor;
• a cylindrical stator core disposed on an outer circumferential side of the rotor;
• a main body including a shell integrally formed with the stator core;
• a bracket attached to one end side of the main body and formed having a gap between the bracket and the rotor in an axial direction of the rotation axis;
• and
• a bearing that rotatably supports the shaft, wherein
• the bracket includes a magnetic bearing house portion that stores the bearing, and a non-magnetic portion that is connected to the bearing house portion,
• the bearing house portion includes a tubular portion and a flange portion extending outward in a radial direction from one end side of the tubular portion,
• an outer circumferential edge portion of the flange portion of the bearing house portion is disposed on an inner diameter side relative to the permanent magnet portion as viewed from an axis direction of the rotation axis, and is covered with the non-magnetic portion, and
• the tubular portion of the bearing house portion and the non-magnetic portion of the bracket are disposed opposite each other in a radial direction perpendicular to the axial direction, and a clearance portion is formed between the tubular portion and the non-magnetic portion.
