Hand-Held Power Tool with an Electromotive Drive and at least a First Housing Part

Abstract

A hand-held power tool comprises an electromotive drive that is configured to drive an output shaft and that is positioned in a first housing part, wherein the electromotive drive and the output shaft define a common first axis. The hand-held power tool further comprises an electronic system that is configured to energize the electromotive drive and that is positioned in a second housing part. The second housing part is elongated and includes a grip that is distal from the electromotive drive. The second housing part defines a second axis that is at an angle to the first axis between 60° and 120°.

What is claimed is: 
     
         1 . A hand-held power tool, comprising:
 a first housing part;   a second housing part;   an electromotive drive configured to drive an output shaft and positioned in the first housing part, the electromotive drive and the output shaft defining a common first axis; and   an electronic system configured to energize the electromotive drive and positioned in the second housing part,   wherein the second housing part is elongated and includes a grip that is distal in relation to the electromotive drive, and defines a second axis that is positioned at an angle in relation to the first axis; and   wherein the angle is between 60° and 120°.   
     
     
         2 . The hand-held power tool according to  claim 1 , wherein the angle is between 80° and 110°. 
     
     
         3 . The hand-held power tool according to  claim 1 , wherein the first housing part has a height along the first axis between 60 mm and 150 mm. 
     
     
         4 . The hand-held power tool  claim 1 , wherein the second housing part is formed by one or a plurality of housing shells, and is fastened to the first housing part. 
     
     
         5 . The hand-held power tool according to  claim 1 , wherein the second housing part is rotatably mounted to the first housing part. 
     
     
         6 . The hand-held power tool according to  claim 1 , wherein:
 the electromotive drive is a modular electromotive drive;   the first housing part includes an inner flange; and   the modular electromotive drive is fastened to the inner flange.   
     
     
         7 . The hand-held power tool according to  claim 1 , further comprising an outer flange that outwardly closes off the first housing part. 
     
     
         8 . The hand-held power tool according to  claim 7 , further comprising:
 a protective cover,   wherein the outer flange includes a collar; and   wherein the protective cover is attached to the collar.   
     
     
         9 . The hand-held power tool according to  claim 1 , wherein the electromotive drive is an electronically commutated electric motor. 
     
     
         10 . The hand-held power tool according to  claim 1 , wherein the electromotive drive is a multi-pole electromotive drive having six or more pairs of poles. 
     
     
         11 . The hand-held power tool according to  claim 9 , further comprising a tool spindle, wherein the electronically commutated electric motor is configured to drive the tool spindle. 
     
     
         12 . The hand-held power tool according to  claim 1 , wherein the second housing part includes a fan configured to cool the electronic system. 
     
     
         13 . The hand-held power tool according to  claim 1 , wherein the first housing part includes at least one sensor configured to detect a rotational position of the electromotive drive. 
     
     
         14 . The hand-held power tool according to  claim 1 , wherein the hand-held power tool is an angle grinder.
