PROBLEM TO BE SOLVED: To provide a DC motor, an apparatus and a method for driving DC motor which control unbalance in generation of heat of brush to realize a small size and high output DC motor. SOLUTION: For a DC motor having four or more brushes 11 to 14 and four or more poles, the power lines 61 to 64 are led from the brushes exceeding the number of poles, these power lines are respectively connected to the power elements 21a, 22a, 23a, 24a, 21b, 22b, 23b, 24, different voltages are applied to the brushes exceeding the number of poles and brush currents exceeding the number of poles are respectively controlled. |
