Four control modes of servo drive

1.Feedback compensation open loop control. The accuracy of open-loop system is low, because the step error , start stop error and mechanical system error of servo driver will directly affect the positioning accuracy. This system has the advantages of both open-loop and closed-loop, that is, it has the stability of open-loop and the accuracy of closed-loop.

Classification of air-conditioning compressors

The air-conditioning compressor plays the role of compressing and driving the refrigerant in the air-conditioning refrigerant circuit. The working circuit is divided into an evaporation area (low pressure area) and a condensation area (high pressure area). The indoor unit and outdoor unit belong to the high-pressure or low-pressure area (depending on the working state), and the compressor is generally installed in the outdoor unit.

What is the refrigerator compressor used for

　Refrigerators use evaporative cooling or vaporization to absorb heat to achieve the purpose of refrigeration. The throat of the refrigerator is filled with a refrigerant known commercially as Freon, commonly known as refrigerant. A commonly used one is difluorodichloromethane, which is a colorless, odorless and non-toxic gas with a boiling point of 29°C. Freon is pressurized by the compressor when it is in a gas state.
