The loss of the geared motor itself causes the temperature to rise, and the temperature is one of the important factors determining the rating and life of the machine. Generally, a geared motor has different temperature upper limits depending on the type of insulating material used, and the power that can be used for the semiconductor component depends on the temperature (referred to as the joint temperature). For the technical staff, it is very important to have knowledge about the heat, but it is difficult to have the opportunity to absorb practical knowledge.
When discussing heat flow and its traits, the first thing to do is to understand the meaning and unit of the term (term) about heat. Here are several terms, such as temperature, energy, and specific heat. , heat capacity, etc.
1. Temperature, indicating that there are three types of temperature, one is used daily (°C: Celsius, Celsius), the other is used in the English-speaking countries (°F: Fahrenheit, Fahrenheit), and the other is in the field of physical chemistry. The absolute temperature used (K: Kelvin). The unit of °C is a unit for expressing temperature at a temperature of 1 at a pressure of 100 ° C of water and a freezing point of 0 ° C at which water and water coexist. The unit of °F is a unit for expressing temperature based on two temperatures of a boiling point of 212 °F and a freezing point of 32 °F in a state of 1 atm.
2. Heat, the unit of heat value (Energy) is the same as (J:Joule, Joule), which can be related to electric energy by the relationship of 1J=1W.s. In addition, it has been The unit of heat used (cal: card) is still in use today in some occasions.
3. Specific heat, the so-called specific heat, is the heat required to increase the temperature of a substance weighing 1g by 1 ° C. The more specific the heat, the less likely it is to raise the temperature, and the less likely it is to cool down.
4. Heat capacity, assuming that the mass of a substance is M (g) and the specific heat is c (J / ° ° C), the heat capacity is Mc (J / ° C), the so-called heat capacity, is to increase the temperature of the south of the object by 1 ° C The amount of heat needed.
