  • Patent number: 4783608
    Abstract: An electric motor provided with a bearing of improved design has a stator (1) supported by a mounting frame (3) and a rotor (4) in rigidly fixed relation to a shaft (5), the shaft being rotatably mounted in a plain bearing (7) placed within a tubular support (8) which is rigidly fixed to the motor frame (3). A sleeve (23) composed of material having a sufficient degree of elastic deformability to absorb vibrations is interposed between the outer face (24) of the bearing (7) and the inner face of the tubular support (8). The electric motor is intended in particular to equip propeller-type fans and is primarily applicable to direct-current motors of the electronic commutation type.
