Servo planetary reducer is easily affected by temperature. When the temperature of the servo reducer exceeds the maximum operating temperature, or the temperature rise exceeds the specified value, or although the temperature rise does not exceed the specified value, the temperature suddenly increases when the load is low, indicating that the servo reducer has malfunction.
1. The limit working temperature of the insulating material refers to the temperature of the hottest spot in the winding insulation during operation of the servo reducer during the design life expectancy. If the operating temperature exceeds the limit operating temperature of the material for a long time, the aging of the insulation will increase and the life span will be greatly shortened. Therefore, the temperature is one of the main factors of the service life of the servo planetary reducer in operation.
2. The temperature rise is the temperature difference between the servo planetary reducer and the environment, which is caused by the heating of the servo reducer. Temperature rise is an important indicator in the design and operation of the servo planetary reducer. It marks the degree of heat generation of the reducer. If the temperature rise suddenly increases during the operation of the reducer, it indicates that the planetary reducer is faulty, or the air duct is blocked or the load is too heavy.
3. The core of the servo planetary reducer in operation will produce iron loss in the alternating magnetic field, copper loss will occur after the winding is energized, and there are other stray losses too. These will increase the temperature of the servo reducer. On the other hand, the servo planetary reducer will also dissipate heat. When the heat generation and heat dissipation are equal, the equilibrium state will be achieved, and the temperature will no longer rise and stabilize at a level. When the heat generation increases or the heat dissipation decreases, the balance will be broken, and the temperature will continue to rise, and the expansion of the temperature difference will increase the heat dissipation, and reach a new balance at another higher temperature.
