New description: [New technical field] This creation is related to a kind of spindle motor for surface grinder, especially a kind of structure with simple structure and quick assembly, and also has a crane sound, environmental protection and health crane. . [Prior Art] According to the conventional spindle motor for the surface grinder shown in the first to third figures, the stator (2) is mainly disposed in the motor casing (1), and the inside of the stator (2) is passed through the - axis (3) through the L rotor (4). ), at both ends of the shaft (3), the bearing (7) inside the front and rear covers (5, 6) of the motor casing is sealed, so that the shaft (3) driven by the rotor rotates more smoothly' and the shaft center (3) passes out. The rear cover end listens to the fine fan (8), and then the fan cover (9) combined with the rear end of the motor peripheral (1) to prevent accidental contact with the fan driven by the shaft center, thus the currently commercially available spindle Motor structure. The above-mentioned 1 knows that [the main structure design of the "spindle motor for surface grinder" used in the shell, although it can achieve the design amount of the Lai, but it also has the following technical issues: The heat generated by the rotor of the motor is dependent on The fan of the outer cover a of the back cover is designed to prevent the riding of the fan by the fan connected with the rotor, which basically causes the problem of increasing the cost of the fan transportation, and the fan cover structure of the fan is prevented from being accidentally touched by the fan. Structure County _ can not be reduced. Since the spindle motor has added a fan cover to protect the user's fan cover, it not only directly reflects the cost disadvantages, but also increases the assembly and maintenance of the spindle motor. Thirdly, it provides bearings with smoother rotor rotation. The traditional design is located on the front cover 5 M339853 and the inner side of the rear cover. This design will cause the front and rear covers to be processed for multiple times, and the machining precision. Can't be more sophisticated. Fourth, the spindle motor adds a fan structure, which will generate noise during the operation of the fan. This situation is for the quiet empty _# ring rainbow author, it is expected to cause the lack of attention. Fifth, the spindle motor used in the surface grinder, although the front and rear covers are sealed, but the rear end of the shaft still penetrates the back cover to combine the design of the fan, which is easy to cause the fine dust generated by the grinding of the workpiece due to the surface grinding process. The venting of the fan cover enters the hoisting. When the fan is running, it will also blow the defensive dust, causing the floating dust to fly in the air, causing the operator to inhale too much dust and affect the health. In view of the above-mentioned technical problems existing in the conventional surface polishing spindle motor, the creator has developed a "closed fanless spindle motor" that can completely eradicate the above technical problems by virtue of the experience of the related industries. [New content] φ The main purpose of this creation is to provide a closed fanless spindle motor with a compact structure. The purpose of this creation is to provide a low-cost, wind-free shaft motor.

After the motor casing is closed, the outer surface of the cover is spaced apart. M339853 is right-handed, ', fin α The thermal energy guiding and heat-discharging effect generated by Dama Motor replaces the use of the conventional heat-dissipating fan, which naturally simplifies the fan and protects the user's fan cover. The structure of the spindle motor is simple and low-cost. Advantages As far as the creation of the fanless flat bribe is better, the structure of the motor and the space implementation are as follows: the jU is closed, but the drawing is only the single-real & secret of the spirit of the creation.
