Abstract (en)
[origin: EP1886962A1] An object is to provide a traction machine for elevators in that, despite motor's heat generation, heat distortion of a housing base is small. To achieve the object, the machine comprises: the base having a tubularly formed cylindrical section, and a bottom section provided closing over one side of the cylindrical section; stator windings for a motor, the windings provided on the cylindrical section; a rotor for the motor, the rotor supported rotatably in the axial center of the base; a brake member disposed on the rotor; and a brake disposed on the base that correspondingly operates to brake on the brake member. At least one part of the bottom section is formed into a curved surface, in which the bottom section is formed with the curved surface protruding toward the rotor's mounted side. Thereby, high membrane stiffness of the bottom section is assured, and heat distortion of the base becomes small.
