PROBLEM TO BE SOLVED: To provide a drive method for a battery-driven product which can make applied currents uniform and can extend the operation life time of a battery. SOLUTION: This drive method for a battery-driven product employs a 1-2 phase drive method. If an applied current value in a one-phase drive state is defined as '1', respective current values applied to the respective phases in a two-phase drive state are set to '1/2'. |
