Hand-Held Power Tool having an Electronically Commutated Electric Motor and an Integrated Electronics System

摘要

A hand-held power tool, in particular an angle grinder, having a drive unit, has an electronically commutated electric motor and has an electronics system which is integrated in an appliance housing. The ratio of a weight of the hand-held power tool MHWZM to a nominal power PN is selected in such a way that, in a power range of from 0 to 1200 W, the ratio of the weight of the hand-held power tool MHWXM to the nominal power PN is at most 0.75 g/W*PN+1200 g, and, at a value of the nominal power of greater than 1200 W, the ratio of the weight of the hand-held power tool to the nominal power is at most 2.2*PN−540 g.

1. A hand-held power tool having a drive unit, comprising:
an electronically commutated electric motor; and an electronics system integrated in an appliance housing, wherein: a ratio of a weight of the hand-held power tool to a nominal power PN is selected such that:
when the nominal power has a value in a range of 0 to 1200 W, the ratio of the weight of the hand-held power tool to the nominal power PN is maximally 0.75 g/W*PN+1200 g, andwhen the nominal power has a value greater than 1200 W, the ratio of the weight of the hand-held power tool to the nominal power PN is maximally 2.2*PN−540 g.
