摘要：
A motor system includes four brushes electrically connected to a rotor. A stator includes two magnetic poles. A circuit selectively rotates the rotor at a first speed by applying a first voltage to a first of the brushes and a second voltage to a second of the brushes. The circuit selectively rotates the rotor at a second speed by applying the first voltage to the first brush or the second brush, and applying the second voltage to a third of the brushes and/or a fourth of the brushes.
