Abstract
Description
Technical Field
[0001] The utility model relates to a cooling device suitable for TWM series synchronous motors, belonging to the technical field of iron ore dressing equipment. Background Art
[0002] The TMW electric synchronous machine is a common power source for overflow ball mills. When the synchronous motor is powered on, the rotor rotates and drives the ball mill through the coupling. The traditional synchronous machine heat dissipation device has the following disadvantages: First, the heat dissipation hole area of the traditional synchronous motor is small, and the cooling effect is not obvious by using an external heat dissipation axial flow fan to blow air to the synchronous motor rotor; second, the natural ventilation method is used, and the ventilation and heat dissipation efficiency is low. As the electric synchronous machine increases in service life, the electrical components of the synchronous motor age and the performance decays, the internal heat of the synchronous motor increases, and the temperature rises. When the internal temperature reaches 130°C, the synchronous motor automatically alarms and shuts down, resulting in a low equipment operating rate and affecting the concentrate output. In summary, the traditional synchronous machine heat dissipation device can no longer meet the use requirements of existing synchronous motors. Utility Model Content

[0017] Six circular holes with a diameter of 10 mm are evenly distributed on the circular flange 2 , and the circular holes on the hot air collection box 3 are the same as the circular holes on the circular flange 2 and correspond to each other one by one.
