Abstract
A battery-operated hand power tool, in particular an eccentric sander, includes at least one electronically commutated electric motor that acts upon an output shaft and that is configured to drive a working tool. The hand power tool further includes at least one motor housing part that accommodates the electronically commutated electric motor. The electronically commutated electric motor and the output shaft define a common first axis that is coaxial with the output shaft. At least one handle region of the hand power tool accommodates at least one set of electronics configured to energize the electronically commutated electric motor. The motor housing part and the handle region are disposed at an angle to each other. The working tool has a diameter that is between 75 and 150 mm, but preferably is between 115 and 125 mm.
