Claims

[Claims for Utility Model Registration] 1. A bearing storage chamber 14 extending on the axis of the rotor 3 is provided in the casing 4 of the rotor 3.
The first bearing 12 is press-fitted into one end thereof, and the second bearing 13 is fitted loosely into the inner periphery of the bearing storage chamber 14 at the other end. Vertical end face 3 on the side opposite to the first bearing
2 and the second bearing 13, this second bearing 1
The shaft of the second bearing 13 is interposed between the bearings 12 and 13 so that the elastic member 33 abuts on the outer ring side of No. A spacer 31 for regulating the directional position is interposed, and the fixed shaft 20 is inserted into each of the bearings 12, 13 and the spacer 31 in a loose fit state to rotatably support the rotor 3. An electric motor characterized by: 2. A permanent magnet 6 is arranged along the inner peripheral surface of the cylindrical portion 5 in the casing 4 of the rotor 3, and
A bearing storage chamber 14 is provided at the axial center of the casing 4, the bearing 12 is press-fitted into the bearing storage chamber 14, and the fixed shaft 20 to which the stator 27 is fixed is inserted into the bearing 12 with a loose fit. While supporting the rotor 3 rotatably, the fixed shaft 20 is formed with a step 34 that abuts one side of the inner ring of the bearing 12, and at the position where the bearing 12 contacts the step 34, , the axial center of the stator 27, which is located facing the inner periphery of the permanent magnet 6, is closer to the bearing 1 than the axial center of the permanent magnet 6.
2. An electric motor characterized in that the electric motor is configured to be located at a position in the direction of contact with the step 34 of No. 2.
