Abstract
The invention relates to a winding body for an electric motor and, in particular a brushless direct current electric motor (200) with an air gap winding. At least two bobbins (12, 14; 22, 24; 32, 34) per stand (10, 20, 30) are provided. The invention also relates to a method for the production of said winding body. According to the invention, the bobbins (12, 14; 22, 24; 32, 34) of a strand (10; 20; 30) of the winding body (100) are wound immediately behind each other.
Claims13
A winding body for an electric motor, in particular for a brushless direct current electric motor (200) comprising an air-gap winding, in the case of which at least two coils (12, 14;
- 22, 24;
- 32, 34) per phase (10, 20, 30) are provided, wherein
- the coils (12, 14;
- 22, 24;
- 32, 34) of a winding phase (10;
- 20;
- 30) of the winding body (100) are wound directly one after the other.
The use of an electric motor (200), in particular an electronically commutating electric motor (200) that comprises an air-gap winding, in the case of which a winding body (100) is located in an air gap (140) between a stator iron core (132) and a rotor (120), for a power tool (210), in particular a power tool (210) that includes an insertion tool (212) that is drivable in a percussive and/or rotary manner, in particular a power tool (210) that is operated using a rechargeable battery.
A power tool, in particular a power tool that includes an insertion tool (212) that is driveable in a percussive and/or rotary manner, wherein
- it includes an electric motor (200), in particular an electronically commutating electric motor (200) that comprises an air-gap winding, in the case of which a winding body (100) is located in an air gap (140) between a stator iron core (132) and a rotor (120).
