摘要： A power tool includes a brushless DC motor having a stator and a rotor pivotably arranged inside the stator, the stator including a first winding, a second winding, and a third winding. Each winding is arranged at at least two opposite poles connected together. The stator windings may be connected in a delta configuration by electrically coupling adjacent terminals of the first and second windings, second and third windings, and third and first windings at three connection points. A baffle may be provided in parallel and adjacent to the stator, the baffle including at least one conductive routing or stamping to facilitate electrically coupling the first, second, and third windings in at least one of a delta or a wye configuration.

摘要： A power tool (1; 90) includes a motor (17) having a stator (18) and a rotor (19). The stator (18) includes front and rear insulators (21, 22) respectively disposed forward and rearward of a stator core (20) in an axial direction thereof. At least six coils (23) are respectively wound on the stator (18) such that the coils (23) are wound through the front and rear insulators (21, 22). Winding wires (23a) respectively electrically connect circumferentially-adjacent pairs of the coils (23).

摘要： A BLDC includes an outer casing, and a first sub-motor and a second sub-motor mounted within the outer casing. The BLDC further includes a terminal hub, and a first conductive terminal set and a second conductive terminal set. The first and second sub-motor include their respective stators that are energized independently and a common rotor. The first conductive terminal set is configured as a power supply branch circuit for the stator of the first sub-motor, the second conductive terminal set is configured as a power supply branch circuit for the stator of the second sub-motor. The first and second sub-motors can be configured to selectively commonly operate as a single motor to output normal power or operate independently. When one sub-motor fails, the other sub-motor can independently operate to ensure reliability and safety of the motor.
