PURPOSE:To prevent an induction motor from overheating due to long time operation by providing a spring between a rotor and a stator, securing a brake lining at the position opposite to a rotor core of the back surface of a bracket ceiling and pressing the rotor to the lining by the force of the spring. CONSTITUTION:The side surface of a brake lining 12 is secured to the lower surface of a bracket 12 to oppose to the outer surface of a rotor 9, and a bracket 13 is indirectly secured to a stator 8. The bracket 13 is formed in a projection which is opened at the lower side, the central projection supports a motor shaft 10 via bearings, the outside of the lower cylinder extends over the upper end of the stator 8, a plurality of tabs are formed on the lower end of the cylinder and secured to the stator 8. On the other hand, a spring 14 is arranged to surround the upper motor shaft 10 of the motor bearing 11, energized to separate the rotor 9 from the stator 8, and the axial force is applied to the rotor 9 so as to contact the brake lining oppositely with the rotor. |
