Abstract
The invention relates to a multipole direct current motor in which the rotor or stator has permanent magnets with several poles. In order to avoid transmission of mechanical shocks which are transmitted to the rotor because of pole changes, either the magnet or the coils are supported flexibly. <IMAGE>
