Why does the use of cold and air conditioning in a car increase fuel consumption because the car cannot carry a compressor

Automotive air conditioning system _ compressor power is not high Knowledge point: The principle of the "refrigeration system" of automobile air conditioners is the same as that of domestic air conditioners. Both use compressors to drive refrigerants to achieve cooling by the principle of "evaporation and heat absorption".

Performance comparison between servo motor and stepping motor

As an open-loop control system, stepping motor has essential connection with modern digital control technology. In the current domestic digital control system, stepping motor is widely used. With the emergence of all digital AC servo system, AC servo motor is more and more used in digital control system. In order to adapt to the development trend of digital control, stepping motor or full digital AC servo motor is mostly used as the executive motor in motion control system. Although they are similar in control mode (pulse train and direction signal), they are quite different in performance and application. This paper compares the performance of the two.
