Abstract
The invention relates to an electric-motor arrangement for a medical, in particular dental, hand piece which has a motor housing () and a rotor () which is arranged in the motor housing () so that it can be rotated about an axis (L) via a first bearing () and a second bearing (). A stator () is arranged around the rotor () in relation to the axis (L). The first bearing () is received in a first bearing flange (), and the second bearing () is received in a second bearing flange (). Both bearing flanges () are composed of metal and adjoin the motor housing () directly by way of their circumferential faces (). As a result, running noise and vibrations can be reduced. Moreover, premature wear and/or failure can be prevented.
