Permanent magnet linear motor and linear vibrator

A linear vibrator comprising a permanent magnet linear motor, a vibrator housing (20), a power module (40) and a control module (30) both received in the vibrator housing (20), one end of the vibrator housing (20) defining a vibrating member (22), the control module (30) being connected with the permanent magnet linear motor, the permanent magnet linear motor comprising a stator component, a rotor component, and a motor housing (6), the stator component and the rotor component being both mounted in the motor housing (6);

• wherein,
• the rotor component comprises a shaft (1), a supporter (9), and a permanent magnet (2), two ends of the shaft (1) respectively extend out of the motor, the supporter (9) is fixedly defined on the middle part of the shaft (1), the permanent magnet (2) is fixedly embedded in the supporter (9);
• the stator component comprises a stator core (4), a frame (11), and a coil winding (8), the stator core (4) is mounted in the motor housing (6), the frame (11) is formed by defining tooth structure on the stator core (4) along a radial direction, the coil winding (8) is coiled on the frame (11);
• a third cover (7) and a fourth cover (7′) are respectively defined at two ends of the motor housing (6), the middle part of the third cover (7) and that of the fourth cover (7′) both define a hole (71), two ends of the shaft (1) respectively pass through the holes (71);
• two sides of the supporter (9) both define a prop (91) parallel to the shaft (1), each of the props (91) defines a guide hole for receiving a guide rail (100), two ends of each of the guide rails (100) pass through the supporter (9), to respectively rest on the third cover (7) and the fourth cover (7′).
