Claim 15:
16. The method according to claim 15, wherein the motor has first, second, third, and fourth terminals, and wherein the motor is configured to be coupled to a power source having a positive terminal and a negative terminal, further comprising:
electrically coupling the first relay such that the first relay when activated electrically couples the first terminal of the motor to the positive terminal of the power source;
electrically coupling the second relay such that the second relay when activated electrically couples the third terminal and the fourth terminal of the motor;
electrically coupling the third relay such that the third relay when activated electrically couples the third terminal of the motor to the positive terminal of the power source;
electrically coupling the fourth relay such that the fourth relay when activated electrically couples the first terminal and the fourth terminal of the motor; and
electrically coupling the second terminal of the motor to the negative terminal of the power source.
