Embodiment Construction

[0030] figure 1 A schematic illustration of a hand power tool 10 with an electric motor 15 is shown. In this embodiment, hand-held power tool 10 is designed as a drill. The electric motor 15 includes a stator 21 and a rotor 22 with a plurality of coils 20 . It goes without saying that the coil 20 can additionally or alternatively also be arranged in the stator 21 . In this case, the rotor 22 is arranged rotatably about an axis of rotation 23 . The coil 20 is connected to a battery pack 30 through an operation switch 25 . In this case, a control device (not shown) can additionally be provided in order to convert or adjust the signal of the operating switch 25 in order to control the electric motor 15 depending on the configuration of the electric motor 15 . The electric motor 15 is used in the hand power tool 10 to drive and rotate a chuck 35 . For this purpose, the electric motor 15 is coupled to the drill chuck 35 .

Abstract

The invention relates to a method for activating the winding wire (50) of a motor (15) and a coil (20) with the winding wire (50). The winding wire (50) is provided with an electrical conductor (55) wrapped by an insulator (60). The electrical conductor (55) is electrically insulated through the insulator (60). The insulator (60) is activated. During activation, the composition of the insulator (60) in the edge layer (86) of the insulator (60) is changed, and/or the surface property, especially the surface tension, of the outer circumferential surface (65) of the insulator (60) is changed.

Description

technical field [0001] The invention relates to a method for activating a coil wire of an electric motor coil, in which case a coil wire having an electrical conductor wrapped by an insulating element is provided, wherein the electrical conductor is electrically insulated by the insulating element. Background technique [0002] A method for impregnating windings with resin is disclosed in DE 60036904 T2, which method has two separate steps for adding particles and for impregnating. In this case, BN or Al2O3 particles are introduced into the liquid impregnating resin in order to improve the thermal conductivity of the impregnating resin. [0003] In said method, it is difficult to ensure that the impregnating resin adheres reliably to the insulation of the coil wire. Frequently, air is embedded in the transition from the insulation to the impregnating resin. The bonding force of the impregnating resin on the coil wire or its insulation is also low, so that in the event of t...
