Abstract
PURPOSE: To keep the gap between a rotor magnet and a driving coil at optimum, by securing the rotor magnet to a rotary shaft with a jig to set a predetermined distance between the bottom of the rotor magnet and one end of the rotary shaft.
CONSTITUTION: This motor comprises the motor magnet 1 shaped like a disc and having a plurality of poles magnetized in the direction of the thickness, the driving coil 3 for driving the rotor magnet, the rotary shaft 4 which rotates together with the rotor magnet, and a bearing 6. One end of the rotary shaft 4 is inserted into a hole 22, which is opend in the jig 9 and has it bottom at a predetermined distance h from the main side 20 of the jig 9. The rotor magnet 1 is tightly fitted on the other end of the rotary shaft 4 in contact with the main side 20 of the jig 9. Thereby, a rotor is formed. The gap between the rotor magnet 1 and the driving coil 3 is kept at optimum without adjusting the magnetic gap of the mangetic circuit. Therefore, the time of assembling is shortened.
