In order to achieve the cooling effect, this method is also used in injection molding applications, but the injection molding machine generally must use a larger power motor and drive unit, and It is often necessary to operate continuously with high load, so a large amount of thermal energy will accumulate in an instant, and the heat transfer efficiency of the airflow is not good, and the surface area of the heat sink cannot be amplified according to the power ratio, thus causing the temperature of the motor and the servo drive to rise when the temperature of the drive exceeds safety. The set value, the protection facility will automatically power off, causing the machine to run out of operation; if the motor temperature is too high, even if it can still operate, its magnetic and coil conduction efficiency will gradually decline, and the rated output must be maintained with a large current. Waste of energy, which may cause the coil to blow. • In addition, these heat must be discharged into the environment, and the ambient temperature is raised. This reduces the temperature difference between the motor and the environment, which reduces the cooling effect and causes discomfort to the operator. The motor is liquid cooled, but the cooling circuit is wound around the motor casing, or The double-layer shell design, the coolant circulates between them, and the cooling effect is achieved by the form number A0101 page 3/10 pages M399545. This method is better than the air cooling method, but it uses external circulation cooling, and its heat is from It takes a little time for the rotor/stator to pass to the outer casing, so the effect of cooling the inside of the motor is still insufficient. In many cases, the problem of overheating is still the same as that of the air-cooled type, and the drive is still cooled by air cooling. Therefore, the trouble of crashing the machine is still unavoidable. The reason is that the creator has the lack of cooling of the existing servo motor, resulting in instability, tripping, etc., which is supported by many years of manufacturing and design experience and knowledge in related fields. Innovative research and improvement of the existing servo motor cooling device, and the creation of this creation.

Therefore, when the servo motor and the servo driver are operated in a medium such as an injection molding agitation switch template or a plastic injection, the filtered cooling liquid is partially injected into the servo motor by the pump of the liquid cooling system, and the heat is directly turned, ^Sub-cooling, part of the radiator in the driver's drive and the heat source is taken out by the connecting pipe. M is cooled by the water & or gas-liquid heat exchanger to recirculate the coolant to the pump for the next cycle. In order to achieve an efficient cooling effect, the servo drive can be continuously operated at an ideal operating temperature to achieve the rated effect.
