  • Patent number: 11938611
    Abstract: A portable power tool includes an electromotive drive with an output shaft defining a first axis and having a first end portion and a second opposite end portion. The first end portion is between a mounted machining tool and the second end portion. The electromotive drive is received in a first power tool housing portion and includes a stator having a first stator end defining a first plane and a second stator end defining a second plane, the first plane is located between the first end portion and the second plane. A second power tool housing portion defines a handle gripping portion with a first surface defining a third plane which intersects the output shaft at a location whereat the first plane is between the third plane and the second plane. A second surface portion opposite the first surface portion defines a fourth plane parallel to the third plane.

  • Patent number: 10730175
    Abstract: A portable power tool, in particular an angle grinder, includes at least one electromotive drive, a first housing, and a rechargeable battery. The electromotive drive, in particular an electronically commutated motor, acts on a drive shaft, and is configured to drive a tool spindle. The first housing has at least one first housing half shell, at least one first housing part configured to receive the electromotive drive, and a second housing part that forms a handle. The battery is configured as a power source for the portable power tool. A ratio of a diameter of the electromotive drive to a diameter of the second housing part is between 0.6 and 1.1, preferably between 0.7 and 0.8.
