Abstract: An electric motor includes a rotor assembly and a stator assembly. The stator assembly includes a plurality of teeth, a plurality of coils supported about the plurality of teeth, and a conductive terminal electrically connected to at least one coil of the plurality of coils. The conductive terminal includes a lead portion. The electric motor also includes a printed circuit board coupled to the stator assembly and electrically connected to the lead portion. The electric motor further includes a solder cup supported on the lead portion between the printed circuit board and the stator assembly. The solder cup includes a wide end facing toward the printed circuit board, and a narrow end opposite the wide end.

Abstract: An electric motor includes a rotor assembly, a stator assembly, a printed circuit board, and a solder cup. The stator assembly includes a lamination stack defining teeth, coils supported about the teeth, and a conductive terminal electrically connected to at least one coil. The conductive terminal includes a lead portion. The printed circuit board is coupled to the stator assembly and includes opposed first and second sides, and a through hole extending through the printed circuit board and receiving the lead portion. The printed circuit board further includes a solder pad surrounding the through hole on at least one of the first side or the second side. The solder cup is supported on the lead portion between the printed circuit board and the stator assembly, and includes a wide end facing toward the printed circuit board, and a narrow end opposite the wide end.

Abstract: A handheld punch tool includes a housing, a die holder coupled to the housing, a die supported by the die holder, the die and the die holder defining a feed slot therebetween for receiving a workpiece to be cut, and a punch configured to reciprocate within the die holder, with a main body defining a first longitudinal axis extending centrally through the main body and a punch element extending from the main body along a second longitudinal axis parallel to the first longitudinal axis. The punch element is configured to cut a first distance into the workpiece per stroke of the punch when the feed slot faces a first side of the punch and to cut a second distance into the workpiece per stroke when the feed slot faces a second side of the punch opposite the first side. The first distance is greater than the second distance.

Abstract: Power tools described herein include a housing, a brushless direct current (DC) motor, a non-conductive terminal mount, and a plurality of terminals. The housing has a motor housing portion, a handle portion, and a battery pack interface. The brushless DC motor is located within the motor housing portion and has a rotor and a stator. The non-conductive terminal mount is located on an outer peripheral surface of the stator and includes an angled surface. The angled surface is not substantially parallel to a longitudinal axis of the motor. The plurality of terminals is mounted on the angled surface of the terminal mount. Each of the terminals is angled in a first direction such that the terminals are not substantially parallel to the longitudinal axis of the motor.
