Abstract

PURPOSE: To reduce the damage to the bearing, by balancing the weight moment by the turn table and that by the permanent magnet so that uniform bearing surface pressure can be obtained.
CONSTITUTION: The DC brushless direct drive motor 1 provides the ring shape permanent magnet 2a and rotary shaft 5, to which the case 3 is coupled via the boss 4 with coking. The printed wiring board 8, coil 10 and coil winding frame 11 are fixed to the fixed plate 12. The bearing 6 is coupled to the rotary shaft in rotary-free. The turn table 16 is screwed to the rotary shaft 5. The DC motor 1 is fixed to the player board 15 via the spacer 13. With this constitution, it is possible to uniform the force exerted to the bearing, the vertical type record player excellent in wow flutter and S/N ratio can be obtained.
