<P>PROBLEM TO BE SOLVED: To reliably prevent interference of a braking disk with a friction member by suppressing the deflection of a rotary block in the axial direction. <P>SOLUTION: A rotary block 2 is formed by integrating a rotor 11 of a motor 7, a drive sheave 12 to hoist a hoisting rope, and a braking disk 10 of a disk brake 9. The rotary block 2 is turned by the magnetic force applied between a stator 8 and the rotor 11 of the motor 7 provided on a base block 1, and a friction member of the disk brake 9 is pressed against a side surface of the braking disk 10 to stop the rotation of the rotary block 2. In such an elevator hoisting machine, the magnetic force application surfaces of the rotor 11 and the stator 8 of the motor 7 face each other in the radial direction. The magnetic force between the rotor 11 and the stator 8 is applied in the rotational direction and the radial direction, and the magnetic force is less applied in the axial direction. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
