摘要： In order to achieve an improved chip and shaving ejection in a portable per, a small portion of the motor cooling air stream is diverted and directed through an air passage into a chip ejection channel. The volume flow of this chip ejection air stream may be controlled by a control slider gate to suit various operating conditions. The chip ejection air stream also serves to cool the drive belt and planing head. The diverted air flow keeps the chips in a sufficiently loose state to assure an effective, clog-free ejection of chips. Furthermore, a deflection flap is used in the chip ejection channel to eject the chips to either side of the tool as desired.

摘要： In a non-commutating-pole commutator motor, in particular as the drive of a power hand tool, a device for reversing the direction of rotation includes a switch (8) for reversing the direction of current in the rotor winding, and a brush apparatus (4) mounted immovably in the motor casing. The rotation of the plane defined by the commutating coils is chosen in such a manner that good commutation is assured in one of the two directions of rotation at full motor output. Furthermore, the switch (8) for reversing the direction of rotation yields the preferred direction of rotation in a first switch position and the opposite direction in a second switch position. In the switch position for the preferred direction, a smaller number of turns of the field winding (1, 2) in the electric circuit of the motor is effectively provided while, in the opposite direction of rotation of the motor, a larger number of turns is effectively provided.
