The engine has reliable heat insulation performance and excellent quality, and can control the quality of basic insulating materials such as electromagnetic wire and pollution coating, Using advanced media analysis, dynamic media measurement is used in the processing of insulation, In order to control the violators in the process of dining, it ensures the stability and reliability of the insulation quality of the engine, and has a high adaptability to over-voltage, The inverter driven by the carrier can also determine the computer control interface according to the user's needs. This helps to automatically Control speed control system. The brake can be installed on the incompressible end of the shaft for quick braking.
