high voltage electric motor with self diagnostic function and lcd display the semiconductor vacuum phase control motor device

摘要

this invention is a device for the high voltage silicon rectifier (SCR) using a high pressure in the high pressure state, the current of the motor soft starting and driving of the semiconductor can be controlled to provide a vacuum status, purpose.;the invention, in order to achieve this, the form and the pressure of the silicon rectifier (SCR) as a cooling plate between the serial port equipment, full insulation state, and is set to two, three phase component, is caused in the rectifier (SCR) come from let in the process (80C 196 KC) to the control unit, the system take the destroyer as the vacuum motor through the current state of the soft, can get the effect.;the above micro process (80C 196 KC) of the decompression phase control system is another implementation such as 6600 bolt, the bolt 3300 large capacity motor installed on the level, the same effect can be obtained.
