ELECTRIC MOTOR STATOR INCLUDING MEANS FOR LIMITING THE VIBRATION AMPLITUDE OF THE FRAME

摘要

The invention relates to an electric motor stator (10) including : an outer frame (12) with a cylindrical body (18); a magnetic member (14) mounted inside the frame (12) and comprising at least two magnetic members (16a, 16b) mounted on an inner cylindrical face (18i) of the body (18) of the frame (12); characterised in that the cylindrical body (18) bears a frame (12) stiffening ring (26) that is coaxial with the cylindrical body (18) of the frame (12) and designed so as to limit at least partially the amplitude of the vibrations of the frame (12) generated during the operation of the electric motor.
