Abstract

See full text

An electric-motor arrangement for a medical, in particular dental, handpiece that has a motor housing and a rotor which is arranged in the motor housing so that it can be rotated about an axis via a first bearing and a second bearing. A stator is arranged around the rotor in relation to the axis. 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.
