Methods and systems for electric motor voltage change

An electric motor assembly comprising:

• a three-phase electric motor comprising a housing;
• a stator mounted in said housing and comprising a bore therethrough, said stator having a plurality of windings, each winding representing a respective phase of said three-phase electric motor;
• a rotor core rotatably mounted in said housing and extending through said stator bore;
• a terminal board assembly comprising a terminal board comprising a terminal block, said terminal block electrically coupled with said windings and configured to electrically couple with an electrical power source, said terminal board assembly further comprising a plug configured for insertion within said terminal block, said terminal block configured to receive said plug in at least one of a first inserted position and a second inserted position, the orientation of said plug relative to said terminal block the same in said first inserted position as in said second inserted position, said terminal block configured to transfer a first voltage to said windings when said plug attached to said terminal block in said first inserted position, said terminal block configured to transfer a second voltage to said windings when said plug attached to said terminal block in said second inserted position, wherein said second voltage higher than said first voltage;
• and
• a mounting structure coupled to said terminal board and said motor such that said terminal board fixedly attached to said motor housing.

A method for changing the operating voltage of a multi-voltage device including a terminal board, a terminal block coupled with the terminal board, and a plug inserted within and received by the terminal block, the terminal block configured to receive the plug in at least one of a first inserted position and a second inserted position, the terminal block including a central axis extending along the length thereof, said method comprising:

• removing the plug from the first inserted position;
• moving the plug linearly along the central axis of the terminal block;
• and
• inserting the plug within the terminal block such that the plug is attached to the terminal board in the second inserted position.
