Abstract: An electrical multiphase machine is proposed with a stator (3) including a winding (5;6) having at least two strands (51, 52, 53; 61, 62) for generating an electromagnetic field, each strand (51, 52, 53; 61, 62) belonging to a different electrical phase; furthermore with a setting device (4) which supplies each strand (51, 52, 53; 61, 62) with a phase current (Ia, Ib, Ic) or phase voltage (Ua, Ub, Uc) in each case as a setting parameter, said setting device (4) including) a separate power amplifier (41a, 41b, 41c, 41d) for each strand (51, 52, 53; 61, 62), so that the setting parameter can be regulated for each strand (51, 52, 53; 61, 62) independently of the setting parameters for the other strands (51, 52, 53; 61, 62) and at least one common connection point (VP) being provided to which at least two of said strands (51, 52, 53; 61, 62) are connected, and wherein an additional active control element (44) is provided for shifting the potential of said connection point (VP).

Abstract: The present invention provides a power tool with a hand proximity detector to detect the hand of an operator and a trigger circuit operable with the detector to control the operation of a light in the housing or to provide a safety lockout function.
