Rotatable inverter

A rotatable inverter comprising:

• a motor which is driven by a DC power source and generates a rotational force;
• a commutator which has a cylindrical body made of an insulating material, and conductive parts which are divided into two parts by non-conductive parts, respectively, having a desired width;
• a plurality of brushes which are respectively contacted with the outer surface of the commutator, one pair of brushes, which are opposite each other, receiving the DC power source, and another pair of brushes, which are opposite each other, outputting the AC power source;
• and
• a transformer which receives the AC power source from the brushes and outputs a predetermined voltage.

A rotatable inverter comprising:

• a motor which is driven by a DC power source and generates a rotational force;
• a commutator which has a cylindrical body made of an insulating material, and conductive parts which are divided into an even-number of parts by non-conductive parts, respectively, having a desired width, and plates which are, respectively, fixed to the side ends of the cylindrical body, each of the conductive parts having an extended portion which is extended to the side ends of the cylindrical body, and the extended portion having a predetermined length;
• a plurality of brushes which are respectively contacted with the outer surface of the commutator, one pair of brushes, which are opposite each other, receiving the DC power source, and another pair of the brushes, which are opposite each other, outputting the AC power source;
• and
• a transformer which receives the AC power source from the brushes and outputs a predetermined voltage.
