Abstract

PURPOSE: To improve engaging force, to reduce the noise, to lengthen the service life and to reduce the size, by providing a notch having a recess in the inner circumference of permanent magnet ring having magnetized outer circumference then filling synthetic resin into said inner circumference and the shaft.
CONSTITUTION: Notch 4 constituted of downward recess 3 and conducting section opening toward inner circumference of permanent magnet 2 is provided at facing position of inner circumference of permanent magnet ring 2 having magnetized rotor magnetic pole 1 on the outer circumference, and when filling the synthetic resin 5 into the inner circumference of permanent magnet 2 and the shaft 6 it flows into the notch 4 and hardens. While hardening at the notch 4, the synthetic resin shrinks in arrow direction A and B to hold the permanent magnet 2 strongly. Consequently the motor noise due to the loosening of the rotor is reduced, and the service life is lengthened while the size is reduced.
