Generator with built-in voltage controller

A generator with a built-in voltage controller comprises a motor, which includes a housing, a stator and a rotor accommodated inside the housing, wherein the generator further comprises:

• a built-in voltage controller which is disposed inside the motor housing and is in electrical connection with the stator;
• the built-in voltage controller has a voltage up-down adjustment control function and includes a current output unit;
• a first loop changeover switch which is a three-pole knife switch type and includes three groups of first loop polar phase contact points;
• one side of the first loop polar phase contact points is corresponding to the current output unit of the built-in voltage controller through the three phase lines for electrical connection;
• the other side of the three groups of first loop polar phase contact points is electrically connected to the current output unit of the built-in voltage controller through the three extended first loop lines;
• a second loop changeover switch which is a three-pole knife switch type and is in a spaced arrangement relationship with the first loop changeover switch;
• the second loop changeover switch includes three groups of second loop polar phase contact points;
• one side of the three groups of second loop polar phase contact points is electrically connected with the three phase lines;
• the other side is corresponding to the three loop lines through the three extended second loop lines for electrical connection;
• a three-phase short-circuit changeover switch which is a three-pole knife switch type and is in a spaced arrangement relationship with the second loop changeover switch;
• the three-phase short-circuit changeover switch includes three groups of short-circuit polar phase contact points;
• one side of the three groups of short-circuit polar phase contact points is electrically connected to each other through a short-circuit wire;
• the other side is correspondingly to the ends of the three phase lines for electrical connection;
• and
• three converted-voltage output lines, with one end electrically connected to the second loop polar phase contact points of the second loop changeover switch, is connected to one side of the second loop lines;
• the other end of the three converted-voltage output lines is used to connect to a power device.
