ABSTRACT:
In a power-driven, hand-held tool provided with a pneumatic motor, the stator of the motor is comprised of a central tube of steel and two end flanges of plastics applied onto the central tube by injection molding. The impeller rotor of the motor is supported within the stator and assembled with the stator to form a complete motor assembly which is supported within the cylindrical housing of the tool by means of elastic rings which protect the tool against oscillations. The motor assembly can be assembled and tested outside the tool housing.
