Abstract
A drive motor for driving a tool holder of a power tool includes a rotor arranged on a motor shaft, an inner stator and an outer stator. The rotor is arranged in the radial direction of the motor shaft between the inner stator and the outer stator. A first winding is associated with the outer stator for operating at a first voltage level and a second winding is associated with the inner stator for operating at a second voltage level. The first and second voltage levels are different from each other.
